select a 'round robin' allocation scheme, which often works better with samples with a decay tail.

This is done by sending MIDI CC #21 with a value of the number of polyphonic voices available.

Sending this CC also resets the round robin to voice 1 (you may like to do this at the start of a song

playback, for example, to ensure consistent results on each play). Sending CC #21 with value 0

reverts to lowest voice allocation.

I-4 Audio Playback with Z Speed

Video

X is retrigger CV

Y is start position CV

Z sets the playback speed

A is left audio output

B is right audio output

Z press retriggers sample

Parameter Min Max Default Description

0 0 99 0 Folder.

1 0 99 0 Selects the sample.

2 0 99 0 Envelope time.

3 0 127 0 Start offset.

This algorithm is much the same as the 'I-1 Audio Playback' algorithm, except that it forgoes

voltage control of the current sample and instead offers a speed control.

Z is the linear speed control. The central position corresponds to the sample playing at its natural

pitch. Positive voltages speed up playback; negative voltages slow it down. Because the scale is

linear it is possible to slow it down all the way to being stopped.

The current sample is selected via parameter 1.

Parameters 0 & 2 are the standard sample folder and envelope time parameters, described above.

MIDI Input: MIDI note on & off messages are handled equivalently to a trigger or gate on the X

input – that is, a note on retriggers the sample, and if the envelope time is non-zero, a note off will

stop the playback.
