Algorithm-specific playlist filename: midi-playlist-free.txt
This algorithm plays MIDI files, converting the MIDI into CV outputs on A & B (as detailed
above).
The current MIDI file is selected via the parameter i.e. by turning the S knob.
The playback speed is set by a combination of the Z knob/CV and the X CV. With both at zero, the
MIDI file plays at 120bpm. Z offers a linear speed control - 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. X offers an exponential (1V/octave) speed control - the speed doubles for every
1V above zero, and halves for every 1V below zero.
Y is a retrigger input. A trigger pulse in excess of 1V will reset the file to the beginning.
MIDI Output: the MIDI file being played is transmitted unaltered on the disting's MIDI output.

X is retrigger or end position CV
Y is start position CV
Z is end position or retrigger CV
A is left audio output
B is right audio output
Parameter Min Max Default Description
0 0 99 0 Folder.
1 0 99 0 Selects the sample.
2 0 99 0 Envelope time.
This algorithm is much the same as the base I-1 Audio Playback algorithm, except that it forgoes
voltage control of the current sample and instead offers control over the sample end point.
X and Z are the retrigger and end position controls.
• If Z is negative, X is the retrigger input, and Z controls the sample end point. So, if you
require manual control over the end point, turn the Z knob counterclockwise to shorten the
sample.
• If Z is positive, Z is the retrigger input, and X controls the sample end point. In this case X
is scaled in the same way as input Y, so varying Y and feeding X the same CV plus a small
offset will give you a short segment of the sample that moves around with the input. The
trigger fed into Z should be a positive pulse over about 1V.
When Z is adjusted through the switching point between these two modes, the display will show
"Xt" or "Zt" (for X trigger or Z trigger) for a short while.
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.
