Description

Read sampled sound (mono or stereo) from a table, with optional sustain and release looping, and high precision. lposcil3 uses cubic interpolation.

Initialization

ifn - function table number

Performance

kamp - amplitude

kfreqratio - multiply factor of table frequency (for example: 1 = original frequency, 1.5 = a fifth up , .5 = an octave down)

kloop - loop point (in samples)

kend - end loop point (in samples)

lposcil (looping precise oscillator) allows varying at k-rate, the starting and ending point of a sample contained in a table (GEN01). This can be useful when reading a sampled loop of a wavetable, where repeat speed can be varied during the performance.
