supercollider server command reference

Reads sound file data from the given starting frame in the file. cmd_notify = 1, These are the currently defined fill routines for use with the /b_gen command. Plug-ins can define commands that operate on buffers. Posts a representation of this group's node subtree, i.e. 1 - add the new group to the the tail of the group specified by the add target ID. An interface-agnostic implementation of specs for SuperCollider server types and commands. cmd_n_mapan = 61, Resident definitions with the same names are overwritten. Clear all scheduled bundles. These are short notes on installing SuperCollider from source on a debian-based Linux distro … in 2019. They can be addressed and controlled by commands to the synthesis engine. SuperCollider is an object-oriented programming language. a series of Commands each preceded by a 32-bit integer byte length. (See Server Guide, as well as Client vs Server for more details on the distinction.) cmd_b_gen = 38, cmd_d_recv = 5, Audio buses are indexed by integers beginning with zero. Set contiguous ranges of control indices to single values. A list of groups may be specified. Replies to sender with the corresponding /n_set command. cmd_c_get = 40, cmd_b_zero = 34, Map a node's controls to read from an audio bus. Command Line Arguments. cmd_n_map = 14, Synths can have their own local controls that are set via commands to the server. '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' Buses are indexed by integers beginning with zero. Set contiguous ranges of buses to sets of values. MacOS9 getting source code for SC Server cmd_n_cmd = 13, Set contiguous ranges of sample indices to single values. 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. Query the status. num is the index of the bus to set. It is used to control scsynth (or supernova) from the SuperCollider language. You. Unit Generator Definitions have names that match the names of SuperCollider language classes used in building Synth Definitions. Allocate buffer space and read channels from a sound file. Supercollider has been around since 1996, and provides a wide array of sound synthesis functions. Buffers are stored in a global array, indexed by integers starting at zero. Loads a directory of synth definitions files. b.sine1(1.0/[1,2,3,4,5,6], true, false, true); //fill the Buffer with wavetable data. When program execution ends, and control is returned to the SuperColliderinterpreter, the interpreter outputs the return value in the "SuperCollider output" pane. the high 32 bits of the original time stamp. 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). The following is a list of all server commands and their arguments. Immediately following the output buses are the input buses, read from the audio hardware inputs. Places node A in the same group as node B, to execute immediately after node B. 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. The tree defines the order of execution of all Synths. an OSC format string: 8 bit ASCII characters, zero padded to a multiple of 4 bytes. cmd_version = 64, This is only meant for getting a few samples, not whole buffers or large sections. cmd_d_free = 53, Fills a buffer with a series of chebyshev polynomials, which can be defined as:cheby(n) = amplitude * cos(n * acos(x)). For each range, the starting control index is given followed by the number of controls to change, followed by the values. 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. Causes a synth to print out the values of the inputs and outputs of its unit generators for one control period. turn off locally in the bundle -- error posting reverts to the "permanent" setting for the next message or bundle. Replies to sender with the following message: Turns on and off printing of the contents of incoming Open Sound Control messages. More may be added to the end of the list in the future.enum { If the node is a group, then it sets the controls of every node in the group. Using this method can cause a click if the node is not silent at the time it is freed. an OSC message to execute upon completion. cmd_b_query = 47, The name of the virtual server to be removed. Any n_set, n_setn and n_fill command will also unmap the control. Example¶ rm vserver lb_vip To remove multiple vservers, use the following command: rm vserver lb_vip[1-3] Buffers are stored in a single global array indexed by integers beginning with zero. For convenience of client-side methods, you can also suppress errors temporarily, for the scope of a single bundle. add the new node to the the tail of the group specified by the add target ID. The command was received too late to be executed on time. The class reference would then only contain descriptions of the class, the methods and their arguments. There are two types, Synths and Groups. Resident definitions with the same names are overwritten. default = 0), number of frames to write (optional. // 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 … cmd_b_set = 35, I get the impression SC developers intended to make this the preferred, or anyway easiest path. Note this is an in-progress (incomplete) implementation. The server will reassign this synth to a reserved negative number. }; copyright © 2002 James McCartney - converted to ScDoc format 2011 by Jonatan Liljedahl, SuperCollider Server Synth Engine Command Reference, converted to ScDoc format 2011 by Jonatan Liljedahl, /usr/local/share/SuperCollider/HelpSource/Reference/Server-Command-Reference.schelp. The SuperCollider synthesis server (scsynth) SuperCollider's sound generation is bundled into an optimised command-line executable (named scsynth). The reply will contain the sent unique ID. Synth Definitions are referred to by name. There could be links to separate guides, tutorials, examples, etc.. Your laptop. See the Command Reference below. 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 Command numbers are listed at the end of this document. 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). This was an experimental version and is really a different program than version 2. A Synth is a collection of unit generators that run together. If number of frames is less than zero, all samples from the starting frame to the end of the buffer are written. This message should be sent in a bundle in non real time mode. Synth definitions are stored in files generated by the SuperCollider language application. If the channels argument is absent or empty all channels are read in the order they appear in the file. The number of bus channels defined as inputs and outputs do not have to match that of the hardware. It uses the reflection and beans mechanism to dynamically create instances of java classes and control t If number of frames is less than zero, the entire file is read. Replies with a /synced message when all asynchronous commands received before this one have completed. A node was turned off. long. cmd_s_getn = 45, 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. default = 1 channel), starting frame in file (optional. All commands are received via TCP or UDP using a simplified version of Open Sound Control (OSC). cmd_g_tail = 23, The trigger ID and value are determined by inputs to the SendTrig unit generator which is the originator of this message. print the parsed contents of the message. The following is a list of all server commands and their arguments. The arguments after the command name are defined by the command. cmd_n_fill = 17, Communicate to the SuperCollider language from IanniX. Register to receive notifications from server. 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 The server sends an /n_info message for each node to registered clients. normalize - Normalize peak amplitude of wave to 1.0. wavetable - If set, then the buffer is written in wavetable format so that it can be read by interpolating oscillators. cmd_n_free = 11, Parallel groups are relaxed groups, their child nodes are evaluated in unspecified order. Replies to sender with the corresponding /b_setn command. 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. If the number of samples to copy is negative, the maximum number of samples possible is copied. any combination of arguments of types: int, float, string or bytes. It is expected that the client will send all control commands. ... install = no--nodoc-y--replaces = supercollider, supercollider-common, supercollider-ide, supercollider-language, supercollider-server, supercollider-supernova < br > The synth server and its client(s) may be on the same machine or across a network. These are the currently defined command numbers. If the first argument is 1, server will remember your return address and send you notifications; if 0, server will stop sending notifications. If input-filename is the underscore character _, then no input file will be read. construct the node order just after the node specified by the add target ID. If the run flag is set back to one, then it will be executed. A Node means a Synth or a Group. int32 - the length in bytes of the following message. Currently only the server commands needed for the "vivid" package are supported. All nodes have an integer ID. Since version information is easily accessible to sclang users via the methods described above, this command is mostly useful for alternate clients. 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. 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. default = -1, see below), number of sequential samples to change (M). A made a very serious "hmmmmmm" sound when I got to the bit about ports. ["/s_new", "void", 1001, 1, 0] // completion message Any n_set, n_setn and n_fill command will also unmap the control. ... above it can be especially helpful to go through the Server Tutorial while referencing the Server Architecture and Server Command Reference. a symbol argument consisting of the letter 'c' or 'a' (for control or audio) followed by the bus's index. A node was moved. 'c1'), number of channels (optional. cmd_p_new = 63, Traverses all groups below this group and frees all the synths. cmd_n_query = 46, Unit Generator Definitions are plug-ins loaded automatically when the program starts. One suggestion is to make a clear distinction of a consistent class reference and other documentation. If the run flag set to zero then the node will not be executed. cmd_g_queryTree = 57, You can see Synths and Groups being created just by looking at the Server graphics. Map a node's controls to read from buses. 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 32 bit single precision floating point number. cmd_n_run = 12, All asynchronous commands send a reply to the client when they are completed. -- 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. These flags can be added together to create a unique single integer flag that describes the true/false combinations for these three options: Fills a buffer with a series of sine wave partials. Effects processes can be created and patched into a signal flow dynamically at scheduled times. This command is sent to all registered clients when a node is created. An interface-agnostic implementation of specs for SuperCollider server types and commands. cmd_b_fill = 37, Allocates zero filled buffer to number of channels and samples. Frees all nodes in the group. If the node is a group, then it maps the controls of every node in the group. Loads a file of synth definitions. Arrayed control values are applied in the manner of n_setn (i.e., sequentially starting at the indexed or named control). the low 32 bits of the original time stamp. The number of channels requested must match the number of channels in the buffer. 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. Auto-reassign synth's ID to a reserved value. Currently only the server commands needed for the "vivid" package are supported. Any n_set, n_setn and n_fill command will also unmap the control. cmd_c_fill = 27, If "leave file open" is set to one then the file is created, but no frames are written until the DiskOut ugen does so. add the new node just before the node specified by the add target ID. A node was turned on. This is the Mac OS 9 version. This command is the mechanism that synths can use to trigger events in clients. cmd_cmd = 4, This is useful when debugging your command stream. Patching between modules is done through global audio and control buses. Buffers are used for wave tables, sample buffers, delay lines, envelopes, or for any other need which can use an array of floating point values. Messages are similar in format to Open Sound Control messages, except that pattern matching of the command name is not performed. and Server Command Reference. a string with tags defined by the types of the arguments to follow. Used for time stamps only. average percent CPU usage for signal processing, peak percent CPU usage for signal processing. The order of nodes corresponds to their execution order on the server. This command is synchronous and only works with the internal server. Adds the node to the tail (last to be executed) of the group. The lowest numbered buses get written to the audio hardware outputs. clear - if set then the buffer is cleared before new partials are written into it. In a multi-client situation, the only way you can be sure what node -1 refers to is to put the messages in a bundle. add the new group just after the node specified by the add target ID. A node ended. Download SuperCollider 2.2.16. Here is the code that came with the example: Update: Processing is comminucating on port 57150 while Super Collider is expecting communication on 57110.I am not sure how to change it, but I am going to research now and will update this comment with my findings.
