Lexicon PCM92 manual Channel Usage Description, Soft Row Parameter

Now the PCM92 unit is identified by the selected base channel, and virtual machines 1, 2, 3, and 4 within the PCM92 are identified by their respective channels.

Channel	Usage	Description
Base Channel	System Level	Use for loading System presets. This is the PCM92 unit’s base channel. The next
		four channels apply to this PCM92 unit’s virtual machines.
Channels	Virtual	Changes parameters in one virtual machine in a System preset on the PCM92 unit
for virtual	machines 1-4	with base channel 0. Use for loading machine presets and changing parameters for
machines 1-4		individual machines.

Bank Dump

The Bank Dump feature lets you copy all the presets in a User bank from one PCM92 to another (or to another MIDI device). Refer to the MIDI Control section on page 20 for information about Bank Dump.

Reverse Bank Dump (Bank “Load”)

You can perform a “reverse bank dump” by recording a bank dump to your MIDI sequencer, then playing that sysex back to the PCM92 to restore the bank.

Continuous Controllers

All PCM92 soft row parameters can be controlled with single, 7-bit control- lers. Each parameter is controlled with the full controller range, regardless of the parameter range. For example, if the controller is at the midpoint of its range (64), the parameter will also be at the midpoint of its range no matter what the actual number.

Continuous Controllers range from 0 to 127. If the parameter range is less than 127, then a small controller change might not result in a parameter update. But the entire range of the parameter can still be accurately con- trolled. In addition, if the actual range of the parameter is greater than 127, MIDI control might be somewhat coarse. This is most noticeable with large delays.

When MIDI is enabled, the PCM92 automatically sends MIDI messages through the MIDI Out port for soft row parameters and preset loads when- ever those actions are performed via the front panel controls.
