oscbnk :: Sig -> Sig -> Sig -> Sig -> D -> D -> Sig -> Sig -> Sig -> Sig -> D -> Sig -> Sig -> Sig -> Sig -> Sig -> Sig -> D -> Tab -> Sig

Mixes the output of any number of oscillators.

This unit generator mixes the output of any number of oscillators. The frequency, phase, and amplitude of each oscillator can be modulated by two LFOs (all oscillators have a separate set of LFOs, with different phase and frequency); additionally, the output of each oscillator can be filtered through an optional parametric equalizer (also controlled by the LFOs). This opcode is most useful for rendering ensemble (strings, choir, etc.) instruments.

csound doc: http://csound.com/docs/manual/oscili.html

oscilikt :: Sig -> Sig -> Tab -> Sig

A linearly interpolated oscillator that allows changing the table number at k-rate.

oscilikt is very similar to oscili, but allows changing the table number at k-rate. It is slightly slower than oscili (especially with high control rate), although also more accurate as it uses a 31-bit phase accumulator, as opposed to the 24-bit one used by oscili.

osciliktp :: Sig -> Tab -> Sig -> Sig

A linearly interpolated oscillator that allows allows phase modulation.

osciliktp allows phase modulation (which is actually implemented as k-rate frequency modulation, by differentiating phase input). The disadvantage is that there is no amplitude control, and frequency can be varied only at the control-rate. This opcode can be faster or slower than oscilikt, depending on the control-rate.

squinewave :: Tuple a => Sig -> Sig -> Sig -> a

A mostly bandlimited shape-shifting square-pulse-saw-sinewave oscillator with hardsync.

This oscillator generates a variable shape waveform that can morph freely between classical shapes sine, square, pulse and saw. The shape is controlled by two interacting values: clip (squareness) and "skew" (symmetry). All shapes use a minimum number of samples per transition (ie, the sharp end of a saw or a pulse uses minimum N samples), this makes output bandlimited. At higher frequency, the minimum sweep rate takes over, so over a certain pitch all shapes "degrade" to sinewave. The minimum sweep rate is i-time configurable. Hardsync (a very quick sweep to phase=0) is supported, and a sync signal is output once per cycle.

csound doc: http://csound.com/docs/manual/vco.html

vco2 :: Sig -> Sig -> Sig

Implementation of a band-limited oscillator using pre-calculated tables.

vco2 is similar to vco. But the implementation uses pre-calculated tables of band-limited waveforms (see also GEN30) rather than integrating impulses. This opcode can be faster than vco (especially if a low control-rate is used) and also allows better sound quality. Additionally, there are more waveforms and oscillator phase can be modulated at k-rate. The disadvantage is increased memory usage. For more details about vco2 tables, see also vco2init and vco2ft.

ares  vco2  kamp, kcps [, imode] [, kpw] [, kphs] [, inyx]

csound doc: http://csound.com/docs/manual/vco2.html

vco2ft :: Sig -> D -> Tab

Returns a table number at k-time for a given oscillator frequency and wavform.

vco2ft returns the function table number to be used for generating the specified waveform at a given frequency. This function table number can be used by any Csound opcode that generates a signal by reading function tables (like oscilikt). The tables must be calculated by vco2init before vco2ft is called and shared as Csound ftables (ibasfn).

kfn  vco2ft  kcps, iwave [, inyx]

csound doc: http://csound.com/docs/manual/vco2ft.html

vco2ift :: D -> D -> Tab

vco2ift is the same as vco2ft, but works at i-time. It is suitable for use with opcodes that expect an i-rate table number (for example, oscili).

vco2init :: D -> SE Tab

vco2init calculates tables for use by vco2 opcode. Optionally, it is also possible to access these tables as standard Csound function tables. In this case, vco2ft can be used to find the correct table number for a given oscillator frequency.

Granular synthesizer with "per grain" control over many of its parameters. Has a sync input to sychronize its internal grain scheduler clock to an external clock source.

partikkel was conceived after reading Curtis Roads' book Microsound, and the goal was to create an opcode that was capable of all time-domain varieties of granular synthesis described in this book. The idea being that most of the techniques only differ in parameter values, and by having a single opcode that can do all varieties of granular synthesis makes it possible to interpolate between techniques. Granular synthesis is sometimes dubbed particle synthesis, and it was thought apt to name the opcode partikkel to distinguish it from other granular opcodes.

syncgrain :: Sig -> Sig -> Sig -> Sig -> Sig -> D -> D -> D -> Sig

Synchronous granular synthesis.

syncgrain implements synchronous granular synthesis. The source sound for the grains is obtained by reading a function table containing the samples of the source waveform. For sampled-sound sources, GEN01 is used. syncgrain will accept deferred allocation tables.

syncloop :: Sig -> Sig -> Sig -> Sig -> Sig -> Sig -> Sig -> D -> D -> D -> Sig

Synchronous granular synthesis.

syncloop is a variation on syncgrain, which implements synchronous granular synthesis. syncloop adds loop start and end points and an optional start position. Loop start and end control grain start positions, so the actual grains can go beyond the loop points (if the loop points are not at the extremes of the table), enabling seamless crossfading. For more information on the granular synthesis process, check the syncgrain manual page.

Small differences in initial conditions rapidly lead to diverging values. This is sometimes expressed as the butterfly effect. If a butterfly flaps its wings in Australia, it will have an effect on the weather in Alaska. This system is one of the milestones in the development of chaos theory.

pluck :: Sig -> Sig -> D -> Tab -> D -> Sig

Produces a naturally decaying plucked string or drum sound.

Audio output is a naturally decaying plucked string or drum sound based on the Karplus-Strong algorithms.

repluck :: D -> Sig -> D -> Sig -> Sig -> Sig -> Sig

Physical model of the plucked string.

repluck is an implementation of the physical model of the plucked string. A user can control the pluck point, the pickup point, the filter, and an additional audio signal, axcite. axcite is used to excite the string. Based on the Karplus-Strong algorithm.
