## tabrec

tabrec — Recording and playing-back control signals.

## Description

Record and playback control-rate signals on trigger-temporization basis.

## Syntax

    tabrec   ktrig_start, ktrig_stop, knumtics, kfn, kin1 [,kin2,...,kinN]

    tabplay  ktrig, knumtics, kfn, kout1 [,kout2,..., koutN]

## Initialization

## Performance

ktrig_start -- start recording when non-zero.

ktrig_stop -- stop recording when knumtics trigger impulses are received by this input argument.

knumtics -- stop recording or reset playing pointer to zero when the number of tics defined by this argument is reached.

kfn -- table where k-rate signals are recorded.

kin1,...,kinN -- input signals to record.

ktrig -- starts playing when non-zero.

kout1,...,koutN -- playback output signals.

tabrec and tabplay opcodes allow to record/playback control signals on trigger-temporization basis.

tabrec opcode records a group of k-rate signals by storing them into kfn table. Each time ktrig_start is triggered, tabrec resets the table pointer to zero and begins to record. Recording phase stops after knumtics trigger impluses have been received by ktrig_stop argument.

tabplay plays back a group of k-rate signals, previously recorded by tabrec into a table. Each time ktrig argument is triggered, an internal counter is increased of one unit. After knumtics trigger impluses are received by ktrig argument, the internal counter is zeroed and playback is restarted from the beginning, in looping style.

These opcodes can be used like a sort of ``middle-term'' memory that ``remembers'' generated signals. Such memory can be used to supply generative music with a coherent iterative compositional structure.
