Oberheim Matrix-12 - Page 142

The 12 permanent modulations are simply ON/OFF functions and their amounts
are pre-set in the MATRIX-12's permanent memory. The 20 Matrix Mods,
however, are completely variable - all having VALUE X ranges from -63 to +63 to
acheive positive (normal) and negative (inverted) effects. The numbers along
these ranges are not absolute values and may differ from source to source in their
ultimate effect on the sound. They are intended to be regarded simply as an
index that you can use as a reference when programming Patches.
For purposes of reference, and for the discussion to follow, the table below lists
the 47 possible Destinations that can be modulated in the MATRIX-12:
5 Envelopes X5 Destinations per Envelope = 25 total
LFO X SPEED
AMP
5 LFOs X 2 Destinations per LFO = 10 total
RAMP X None
