Writes audio output to a disk file. STKShakers — STKShakers is an instrument that simulates environmental sounds or collisions of multiple independent sound producing objects. In this article, the csoune of utilizing Csound for the creation of expressive musical gestures has been shown, with emphasis on descriptions at the opcode level. GEN51 — This subroutine fills a table with a fully customized micro-tuning scale, in the manner of Csound opcodes cpstuncpstuni and cpstmid.

HOW TO USE THIS MANUAL

The more familiar you become with typing out Csound code, the more proficient you will become at implementing your own ideas from low level principles; your focus will shift from the code itself to the musical idea behind the code. MixerGetLevel – Gets the level of a send to a buss. The morph is performed by linearly interpolating the parameter envelopes frequency, amplitude, and bandwidth, or noisiness of the bandwidth-enhanced partials according to control-rate frequency, amplitude, and bandwidth morphing functions.

MixerSend — Mixes an arate signal into a channel of a buss. Csound Features and Opcodes In one sense, the ability of computers, through audio applications, to recreate the broad range capable of human musical expression is an aspired goal.

GEN19 — Generate composite waveforms made up of weighted sums of simple sinusoids. Has a sync input to sychronize its internal grain scheduler clock to an external clock source. The negative p3 field in the score may also be recognized by a conditional statement in the instrument to branch conditionally and apply envelopes.

Interestingly this is something most live performers are not able to do and they leave the overall sound to the sound engineer running the sound system. Codes a signal into the ambisonic B format. This opcode will send note events from a source machine to one destination. FLloadsnap – Loads all snapshots into the memory bank of the current orchestra. GEN11 – Generates an additive set of cosine partials. GEN03 – Generates a stored function table by evaluating a polynomial.

FLxyin – Senses the mouse cursor position in a user-defined area inside an FLpanel. GEN13 — Stores a polynomial whose coefficients derive from the Chebyshev polynomials of the first kind. FLslidBnkGetHandle — gets the handle of last slider bank created.

If an opcode accepts arguments at different rates, it is called polymorphic [4]. By implementing expressive features, the rendered audio can have qualities which evolve and change over time, in order to achieve a result which can help with the gestures of expression.

The phase amplitude or frequency are summed with a beginning amplitude or frequency, and those are multiplied times a target amplitude or frequency, then the whole phrase is multiplied times a default random amplitude or frequency.

Opcode development in Csound has provided tools which are flexible under a wide range of conditions, and make it possible to develop musical gestures over which one has extensive control. GEN52 – Creates an interleaved multichannel table from the specified source tables, in the format expected by the “ftconv” opcode.

FLlabel FLloadsnap – Loads all snapshots into the memory bank of the current orchestra. GEN31 – Mixes manua, waveform specified in an existing table.

JackoTransport — Control the Jack transport. The goal of this manual is to provide a readable introduction to Csound. This is without the sense of touch, pressure, vibration, sound location, and level of intensity that the live performer feels and reacts to immediately. Or converts an a-rate value to a k-rate value by down-sampling. GEN16 — Creates a table from a starting value to an ending value. GEN05 — Constructs functions from segments of exponential curves.

FLslidBnkGetHandle — gets the handle of last slider bank created.

Conclusion In this article, the usefulness of utilizing Csound for the creation of expressive musical gestures has been shown, with emphasis on descriptions at the opcode level. GEN16 – Creates a table from a starting value to an ending value. GEN20 — Generates functions of different windows. The call is perfomed in the global environment, and the result the returning value is copied into the Csound output variables specified.

Tempo and rhythmic analysis are often used to measure expressivity in performance and to differentiate between peformances.
