Oberheim Matrix-12 User Manual

As we have just seen in the SINGLE/MULTI PATCH PAGE SELECT section,
there are a number of pre-determined Modulation Routings designed into each of
the eight Patch Editing Sub-Pages -12 to be exact. These 12 "hardwired" (or
permanent) modulations were chosen because of their usefulness and also
because they are the most commonly required routings in performance
synthesizers like the MATRIX-12. For reference, we've listed them below:
There will be times, however, that these permanent routings do not offer the kind
of modulation that you really need to do the job. That's why we've created the
MATRIX MODULATION System. This system permits taking any one of the
MATRIX-12's 27 modulation Sources (some of them we already discovered in the
SINGLE/ MULTI PATCH PAGE SELECT Sub-Pages) and routing it to any of the
47 available destinations. That's 1,269 new discrete combinations, not even
counting multiple-modulation chains. You are permitted to create 20 Matrix
Modulation™ Pages that make the possibilities practically limrtlessf.
With the 12 permanent and 20 "custom" Modulation Routings available, you have
an unprecedented total of 32 modulations per patch - and they are all
programmable. You will soon find that the MATRIX-12 gives you incredible
flexibility when programming modulation in a patch.
Matrix Modulation Theory
What exactly is modulation? To modulate means to "change". Modulation is simply
chaging something by something else. In the strictest use of the term, even the
MATRIX-12's Keyboard is a source of modulation. We've already seen how it can
change the pitch of the VCOs and the VCF Frequency (KEYBD select in Page 2
of the VCOs and VCF/VCA). Using Matrix Modulation, the Keyboard can be used
to change 44 other parameters as well.
t For those of you interested in the mathematics behind this, the actual number of
possibilities is 4.1471 x 10^3 That's just over 40 million billion trillion quadrillion
combinations in which no two ever repeat and does not take into consideration
different VALUE X amounts. If we include all the possible VALUE X amounts in
our equation, the number comes to 5.7368 x 10®5 with no two combinations ever
repeating. Have fun.
