Sent in response to all asynchronous commands. Each command has a command number which can be sent to the server as a 32 bit integer instead of an OSC style string. audio music programming-language c-plus-plus sound supercollider synthesis C++ GPL-3.0 573 3,463 630 (46 issues need help) 37 Updated Nov 24, 2020. qpm construct the node order at the tail of the group specified by the add target ID. (optional) some commands provide other information, for example a buffer index. Needed. Sent only to the sender of the original message. Takes a list of pairs of control indices and values and sets the controls to those values. One of -u or -t must be supplied. Resident definitions with the same names are overwritten. supercollider An audio server, programming language, and IDE for sound synthesis and algorithmic composition. SuperCollider. cmd_p_new = 63, If the node is a group, then it maps the controls of every node in the group. an OSC format string: 8 bit ASCII characters, zero padded to a multiple of 4 bytes. It forwards OSC messages and has a number of allocators that keep track of IDs for nodes, buses and buffers. If the audio bus index is -1 then any current mapping is undone. Download sources. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. Takes a list of triplets of control names or indices, bus indices, and number of controls to map and causes those controls to be mapped sequentially to buses. Many asynchronous commands can contain an OSC message or bundle to be executed upon completion. If input-filename is the underscore character _, then no input file will be read. Stops a node abruptly, removes it from its group, and frees its memory. cmd_n_mapa = 60, All running modules are ordered in a tree of nodes that define an order of execution. If the node is a group, then it maps the controls of every node in the group. Synths can have their own local controls that are set via commands to the server. Parallel groups are relaxed groups, their child nodes are evaluated in unspecified order. As b_read, but reads individual channels in the order specified. Major version number. cmd_b_close = 33, - Server Command Reference - Synth Definition File Format. cmd_sync = 52, Recommended introductory tutorials: Scott Wilson’s SC tutorial - comes bundled with the SC download, as do some more tutorials (…plus here’s a quick reference based on Scott’s tutorial by Andrew McWilliams); Nick Collins’ SuperCollider tutorial has a 12 week course of tutorial files as browseable HTML, and is also available in a downloadable zip cmd_b_get = 42, Non-integer partial frequencies are possible. cmd_n_mapn = 48, add the new node to the the tail of the group specified by the add target ID. If the number of samples to copy is negative, the maximum number of samples possible is copied. Allocate buffer space and read a sound file. The command was received too late to be executed on time. cmd_b_free = 32, cmd_c_getn = 41, ["/s_new", "void", 1001, 1, 0] // completion message cmd_b_query = 47, All asynchronous commands send a reply to the client when they are completed. These are the currently defined command numbers. There are four ways to add the node to the tree as determined by the add action argument which is defined as follows: Controls may be set when creating the synth. a unique number identifying this command. Tutorials. Unit generator definitions are Mach-O bundles (not to be confused with CFBundles). This message now supports array type tags ($[ and $]) in the control/value component of the OSC message. cmd_n_order = 62, When streamed via TCP, messages are each preceded by a 32 bit integer giving the length in bytes of the message. add the new group to the the head of the group specified by the add target ID. Takes a list of pairs of control names or indices and audio bus indices and causes those controls to be read continuously from a global audio bus. If you use a node ID of -1 for any other command, such as /n_map, then it refers to the most recently created node by /s_new (auto generated ID or not). Loads a directory of synth definitions files. Synth definitions are stored in files generated by the SuperCollider language application. Plug-ins can define commands that operate on buffers. When program execution ends, and control is returned to the SuperColliderinterpreter, the interpreter outputs the return value in the "SuperCollider output" pane. clear - if set then the buffer is cleared before new partials are written into it. One of -u or -t must be supplied. It uses the reflection and beans mechanism to dynamically create instances of java classes and control t The Unit generator API is a simple C interface. Takes a list of triplets of control names or indices, audio bus indices, and number of controls to map and causes those controls to be mapped sequentially to buses. cmd_b_setn = 36, If number of frames is less than zero, the entire file is read. Reads sound file data from the given starting frame in the file. cmd_c_setn = 26, The output file sample-format should be one of: int16, int24, int32, float, double. The arguments after the command name are defined by the command. If a command's description contains the word Asynchronous, then that command will be passed to a background thread to complete so as not to steal CPU time from the audio synthesis thread. Example¶ rm vserver lb_vip To remove multiple vservers, use the following command: rm vserver lb_vip[1-3] cmd_s_getn = 45, Replies to sender with the following message: Turns on and off printing of the contents of incoming Open Sound Control messages. Any n_set, n_setn and n_fill command will also unmap the control. default = -1, see below), starting frame in buffer (optional. NUMBER_OF_COMMANDS = 65 'c1'), number of channels (optional. default = 1 channel), starting frame in file (optional. This is only meant for setting a few samples, not whole buffers or large sections. Temporary error suppression may not affect asynchronous commands in every case. cmd_s_newargs = 59, This command is sent to all registered clients when a node is created. Loads a file of synth definitions. If reading a file to be used by DiskIn ugen then you will want to set "leave file open" to one, otherwise set it to zero. For each range, the starting sample index is given followed by the number of buses to change, followed by the value to fill. A node was turned off. b.sine1(1.0/[1,2,3,4,5,6], true, false, true); //fill the Buffer with wavetable data. SuperCollider is an environment and programming language originally released in 1996 by James McCartney for real-time audio synthesis and algorithmic composition. As on other OSses sclang.exe and scide.exe reside in the same application folder on Windows. Synths can send control signals to each other via a single global array of control buses. Turn on or off error messages sent to the SuperCollider post window. cmd_b_write = 31, Set contiguous ranges of sample indices to single values. Frees all nodes in the group. The currently defined buffer fill commands are listed below in a separate section. ++ minor_version ++ patch_version. If the control bus index is -1 then any current mapping is undone. Replies to sender with the corresponding /n_set command. Time stamps are in the same format as defined by Open Sound Control : The top 32 bits are seconds since 1900 and the lower 32 bits represent the 32 bit fraction of one second. cmd_n_map = 14, cmd_b_alloc = 28, Register to receive notifications from server. the low 32 bits of the original time stamp. If you send /s_new with a synth ID of -1, then the server will generate an ID for you. This is only meant for getting a few samples, not whole buffers or large sections. On other systems, such as a Mac, you can simply copy MIDIFile.sc into your SuperCollider Extensions directory (typically [$HOME]/Library/Application Support/SuperCollider/Extensions/ on Mac OS X). cmd_none = 0, See the Node Messaging helpfile. floating point and integer arguments are interpreted as control value. Download SuperCollider 3d5.1. UDP datagrams contain this length information already. See the Command Reference below. They can be addressed and controlled by commands to the synthesis engine. default = -1, see below), number of sequential samples to change (M). I get the impression SC developers intended to make this the preferred, or anyway easiest path. A Server object is a representation of a server application. Buses are indexed by integers beginning with zero. Sound files may be loaded into or written from buffers. If the node is a group, then it sets the controls of every node in the group. Map a node's controls to read from buses. cmd_version = 64, The bundle timestamp will establish the ending time of the file. Responds to the sender with a /b_info message. SuperCollider – Tutorial 04 (More Commands) Authored by Derek Shaw. The Nodes in a Group may be both Synths and other Groups. add the new group just after the node specified by the add target ID. The node ID is the node that is sending the trigger. May be "scsynth" or "supernova". The definition is removed immediately, and does not wait for synth nodes based on that definition to end. Used for time stamps only. 1 to receive notifications, 0 to stop receiving them. default = 0), number of frames to read (optional. All commands are received via TCP or UDP using a simplified version of Open Sound Control (OSC). You can see Synths and Groups being created just by looking at the Server graphics. In addition no notifications are sent when there are changes of state for this node, such as /go, /end, /on, /off. /b_gen does not accept a completion message as the final argument. It's all in that one file. Traverses all groups below this group and frees all the synths. cmd_clearSched = 51, How to add the new group according to following from SuperCollider Server Command Reference: 0 - add the new group to the the head of the group specified by the add target ID. cmd_g_new = 21, The Server has a graph of all the running Synths, which may be organised into Groups for convenience. cmd_quit = 3, If the node is a group, then it maps the controls of every node in the group. The synth server and its client(s) may be on the same machine or across a network. Any n_set, n_setn and n_fill command will also unmap the control. (optional), number of sequential controls to change (M), the ID of the node before which the above is placed (B), the ID of the node after which the above is placed (B). The number of bus channels defined as inputs and outputs do not have to match that of the hardware. SuperCollider is an environment and programming language for real time audio synthesis and algorithmic composition. Similar to sine1 except that each partial frequency is specified explicitly instead of being an integer series of partials. Arrayed control values are applied in the manner of n_setn (i.e., sequentially starting at the indexed or named control). The server will reassign this synth to a reserved negative number. Allocates zero filled buffer to number of channels and samples. Using this method can cause a click if the node is not silent at the time it is freed. cmd_c_set = 25, However, even if this is not done, the next bundle or message received will begin with the standard error posting status, as set by modes 0 or 1. Fill ranges of a node's control value(s). Resident definitions with the same names are overwritten. For the full audio rate signal, the argument must have its rate set to \ar. On Fedora Linux, use MIDIFile.sc(installed in /usr/share/SuperCollider/Extensions/MIDIFile/ by Planet CCRMA package supercollider-midifile). cmd_b_read = 30, -- Implementation of the "Server Command Reference" spec-- The spec changes very, very infrequently, but the reference is-- included in the source of this file-- -- Typically you want to import this qualified, e.g. The git branch name and commit hash could be anything if the user has forked SC, so they should only be used for display and user interface purposes. Create a new synth from a synth definition, give it an ID, and add it to the tree of nodes. Both may be supplied. The audio server has the following features: Open Sound Control access Both may be supplied.-u udp-port-number a port number 0-65535.-t tcp-port-number a port number 0-65535-v verbosity Controls the verbosity of server messages. ["/d_load", "synthdefs/void.scsyndef", This message should be sent in a bundle in non real time mode. A list of groups may be specified. If the run flag set to zero then the node will not be executed. any combination of arguments of types: int, float, string or bytes. Places node A in the same group as node B, to execute immediately after node B. End real time mode, close file. Auto-reassign synth's ID to a reserved value. Clear all scheduled bundles. For each range, the starting sample index is given followed by the number of samples to change, followed by the value to fill. If the run flag is set back to one, then it will be executed. SwingOSC is an OpenSoundControl (OSC) server intended for scripting Java(tm), such as to create graphical user interfaces with AWT/Swing classes. Replies to sender with the corresponding /n_setn command. On Windows though, if sclang is not started from the sclang folder (working directory), sclang will not find the server. cmd_g_dumpTree = 56, average percent CPU usage for signal processing, peak percent CPU usage for signal processing. Get a representation of this group's node subtree. - Server Command Reference - Synth Definition File Format . Removes a synth definition. cmd_b_zero = 34, cmd_n_trace = 10, cmd_u_cmd = 20, The line you refer to is spurious and documentation about running SC on an RPi tells one to ignore it ! A list of groups may be specified. If the node is a group, then it maps the controls of every node in the group. cmd_b_allocRead = 29, Class reference . num is the index of the bus to set. // Get the local server's options o = Server.local.options; // Post the number of output channels o.numOutputBusChannels.postln; // Set them to a new number o.numOutputBusChannels = 6; // The next time it boots, this will take effect // specify a device o.device ="MOTU Traveler"; // use a specific soundcard o.device = nil; // use the system default soundcard // Create a new instance of … Map a node's controls to read from a bus. all the groups and synths contained within it. cmd_g_deepFree = 50, The lowest numbered buses get written to the audio hardware outputs. Replies to the sender with a /g_queryTree.reply message listing all of the nodes contained within the group in the following format: N.B. This command will end non real time mode and close the sound file. The number of channels in the output file is specified with the -o argument. Overtone acts as a client to the Supercollider synthesis server. add the new node just after the node specified by the add target ID. cmd_status = 2, At startup there is a top level group with an ID of zero that defines the root of the tree. 'supercollider:recompile' 'supercollider:open-post-window' 'supercollider:clear-post-window' 'supercollider:cmd-period' 'supercollider:eval' 'supercollider:boot-server' 'supercollider:quit-server' 'supercollider:kill-all-servers' See the method Server:queryAllNodes for an example of how to process this reply. If "leave file open" is set to one then the file is created, but no frames are written until the DiskOut ugen does so. The target node is freed. Move the listed nodes to the location specified by the target and add action, and place them in the order specified. Otherwise the new partials are summed with the existing contents of the buffer. Resident definitions with the same names are overwritten. Since version information is easily accessible to sclang users via the methods described above, this command is mostly useful for alternate clients. The following is a list of all server commands and their arguments. This command is sent to all registered clients when a node is turned off. A made a very serious "hmmmmmm" sound when I got to the bit about ports. cmd_d_loadDir = 7, MacOS9 getting source code for SC Server default = 0), number of frames to write (optional. cmd_n_mapan = 61, As b_allocRead, but reads individual channels into the allocated buffer in the order specified. b = Buffer.alloc(s, 512, 1); //make a Buffer storage area. Sent only to the sender of the original message. Buffers are arrays of 32 bit floating point values with a small descriptive header. A Node means a Synth or a Group. turn off locally in the bundle -- error posting reverts to the "permanent" setting for the next message or bundle. cmd_g_queryTree = 57, Set contiguous ranges of control indices to sets of values. There could be links to separate guides, tutorials, examples, etc.. SuperCollider is an object-oriented programming language. Equivalent to sclang's, Minor version number. Arrayed control values are applied in the manner of n_setn (i.e., sequentially starting at the indexed or named control). Unit Generator Definitions have names that match the names of SuperCollider language classes used in building Synth Definitions. If the server was booted from within SCLang (as opposed to from the command line) there will also be a 'default group' with an ID of 1 which is the default target for all new Nodes. These are the currently defined fill routines for use with the /b_gen command. a buffer of data preceded by a 32 bit length field and padded to a multiple of 4 bytes. eg. These messages are sent by the server in response to some commands. Free all synths in this group and all its sub-groups. Command numbers are listed at the end of this document. The job of scsynth (the server) is to handle all the sound generators, filters, and waveforms it has been told about and to calculate values to send to the sound card. Create a new parallel group and add it to the tree of nodes. The name of the virtual server to be removed. construct the node order at the head of the group specified by the add target ID. For the full audio rate signal, the argument must have its rate set to \ar. cmd_n_setn = 16, A node was moved. Fills a buffer with a series of chebyshev polynomials, which can be defined as:cheby(n) = amplitude * cos(n * acos(x)). The number of channels requested must match the number of channels in the buffer. Audio buses are indexed by integers beginning with zero. cmd_c_get = 40, If opening a file to be used by DiskOut ugen then you will want to set "leave file open" to one, otherwise set it to zero. After using a buffer with DiskOut, close the soundfile and write header information. b.plot; //stored shape (not in special SuperCollider Wavetable format, for clarity) Allocate buffer space and read channels from a sound file. Since version 3.6 SuperCollider consists of three separate components: The sound synthesiser (audio server), the programming language (and language interpreter) and the code editor (integrated development environment, or shortly, IDE). A new Node may be added to the head or tail of the group. See Node Notifications below for the format of the /n_info message. The synth server does not send or receive MIDI. If MIDI is desired, it is up to the client to receive it and convert it to appropriate OSC commands for the synth engine. cmd_n_fill = 17, cmd_n_before = 18, A Node is an addressable node in a tree of nodes run by the synth engine. In a SuperColliderprogram, it is the last value stated in a program that automatically becomes the return value - no special command is required. 1 - add the new group to the the tail of the group specified by the add target ID. The job of sclang (the client) is to interpret the commands you give as written code, and to send instructions to scsynth on your behalf. allocSharedControls(numControls) - set the number of shared control buses. cmd_n_cmd = 13, Start Applications >> Audio & Video >> JACK Control If top left Start button is Green select it This needs to start with no errors Start Applications >> Accessories >> Text Editor (Gedit) Start Tools >> SuperCollider mode Start from SuperCollider menu >> Start Server There are three defined fill routines for sine waves. To eliminate a DC offset when used as a waveshaper, the wavetable is offset so that the center value is zero. If number of frames is less than zero, all samples from the starting frame to the end of the buffer are written. Takes a list of pairs of bus indices and values and sets the buses to those values. A node was turned on. a 64 bit integer. Not all combinations of header format and sample format are possible. Equivalent to the sclang code. If you use ['/error', -1] within a self-bundling method, you should always close it with ['/error', -2] so that subsequent bundled messages will take the correct error posting status. Must be done before the internal server is booted. The following two arguments are only sent if the node is a group: the ID of the head node, -1 if there is no head node. A node was started. - Server Command Reference - Synth Definition File Format. Get contiguous ranges of samples. The SuperCollider 3 Synth Server is a simple but powerful synthesis engine. add the new group to the the tail of the group specified by the add target ID. See /usr/share/SuperCollider/Help/MIDIFile/MIDIFile-samplepatches.rtf for example usage. If the channels argument is absent or empty all channels are read in the order they appear in the file. Set contiguous ranges of sample indices to sets of values. cmd_b_readChannel = 55, This command is sent to all registered clients when a node ends and is deallocated. Immediately following the output buses are the input buses, read from the audio hardware inputs. SC has library objects for this, in particular OSCresponderNode filters incoming OSC messages by command. Set contiguous ranges of control indices to single values. The class reference would then only contain descriptions of the class, the methods and their arguments. cmd_d_freeAll = 8, That is not the issue. It is descended from Smalltalk, considered by many to be the first completely object-oriented programming language. add the new node to the the head of the group specified by the add target ID. Removes all bundles from the scheduling queue. the low 32 bits of the time it was executed. default = 0, see below), number of frames to read (optional. There was a problem. The following is a list of all server commands and their arguments. This command is sent to all registered clients when a node is turned on. Messages are similar in format to Open Sound Control messages, except that pattern matching of the command name is not performed. For each range, the starting control index is given followed by the number of controls to change, followed by the values. cmd_dumpOSC = 39, Any n_set, n_setn and n_fill command will also unmap the control. Sub-groups are not freed. Similar to sine2 except that each partial may have a nonzero starting phase. Replies to sender with the corresponding /c_setn command. Get contiguous ranges of buses. Quit program. The trigger ID and value are determined by inputs to the SendTrig unit generator which is the originator of this message. So this is useful for nodes that are of finite duration and that get the control information they need from arguments and buses or messages directed to their group. a string with tags defined by the types of the arguments to follow. This command is the mechanism that synths can use to trigger events in clients. See RootNode and Default Group for more info. flag; if not 0 the current control (arg) values for synths will be posted, flag: if not 0 the current control (arg) values for synths will be included, flag: if synth control values are included 1, else 0, number of child nodes contained within the requested group, number of child nodes contained within this node.
