You can assign any program to load ANY program. That's what the 'RCV MAP'
and the 'XMT MAP' are used for. These are your "Factor Presets to MIDI Program
Number Conversion Charts."
The way the Factor pedals use MIDI Program Change is like this:
Standard MIDI uses Presets numbered in order from 0 to 127. Factor pedals are
numbered differently because since they have three footswitches, two of those
footswitches are for selecting Presets from Banks of two (1:1 – 1:2, 2:1 – 2:2,
3:1 – 3:2, etc.) and the third footswitch changes Bank. But for MIDI Transmit
purposes each Factor Preset is also assigned to a MIDI Program Change number
from 0-127. The factory default settings are in numerical order, like this:
The numbers in this table can be changed in the System Mode's MIDI
XMT MAP menu to suit your needs.
For example, let's say you have a TimeFactor controlling a ModFactor. When
you select TimeFactor Preset 1:1 you might want it to change ModFactor's Preset
to 3:2 instead of 1:1. If you look at the table above you'll see that Factor
Preset 3:2 corresponds to MIDI Program Change #5 by default. So if you change
TimeFactor's 'XMT MAP' value for "1:1>0" to "1:1>5",
then selecting Preset 1:1 on TimeFactor will load Preset 3:2 on the ModFactor.
The table would then look like this:
Notice that with the above settings, TimeFactor Preset 1:1 and TimeFactor
Preset 3:2 will both select ModFactor's Preset 3:2 because they are both set
to transmit MIDI Program Change #5. This means you can set multiple different
presets on the master pedal to call up the same presets on the slave pedal.
This can come in handy!
You can also change the Receive Map, which is the System Mode's MIDI RCV
The Receive Map is the opposite as it tells the Factor pedal which Preset it
should load when it receives a certain MIDI Program Change number. Again, the
factory default values are in numerical order:
When the master pedal is controlling more than one slave you may want to change
the slave pedals' RCV MAPs and leave the master's XMT MAP on the default settings.
It depends what you want to do, and how complex your setup is. The combination
of an editable Transmit Map and an editable Recieve Map on every Factor Pedal
means a lot of flexibility!
