Destination
This parameter determines whether the currently selected zone transmits only to the PC3K
( Local ), transmits only to the MIDI port ( MIDI ), transmits only to the USB port ( USB_MIDI ),
transmits to a pair of destinations ( MIDI+Local , ULocal , or UMIDI ), or
transmits to all destinations ( UMIDI+Local ).
Channel
The Channel parameter defines the MIDI transmit channel for the currently selected zone. You
can set it to any of the 16 MIDI channels. Normally, you will want each zone on a separate MIDI
channel. This is necessary if you want to combine different programs in the setup.
If two zones have the same MIDI channel (and destination), but they have different program
settings, there will be conflicts: no MIDI device, including the PC3K, can respond correctly to
two different simultaneous Program Change commands on one channel. The result will be that
only one Program Change will be recognized, and every note played will sound double (if Note
Maps are on). This can create odd and unpredictable timing effects, and will reduce your
polyphony by 50%.
Nevertheless, there will be occasions when “stacking” zones on the same MIDI channel might
come in handy. Suppose you want a physical controller on the PC3K to send data for two
different numbered MIDI Controllers on the same channel . In this case, you must create two zones
assigned to the same channel, but with different controller assignments.
Here’s one example: if a receiving synth is using Controller 1 for modulation depth and
Controller #13 for modulation speed, you can increase both the depth and the speed with
Slider A. Start by assigning Slider A in Zone 1 to MWheel and in Zone 2 to MIDI 13 ; then assign
both zones to the same MIDI channel. (You may want to make sure you aren’t sending doubled
notes. Use the Note Map parameter on the KEY/VEL page to set one zone’s Note Map to Linear
and the other zone’s Note Map to Off .)
Another example: create two or more zones that are identical except for their transposition
settings. Now you can play parallel intervals (or chords) with single keystrikes.
MidiBank
Before reading this section on MIDI Banks, be sure to read the note in the section
Program on page 7 ‐ 6.
The PC3K’s programs are divided into 17 MIDI Banks, numbered 0–16. Program 46 in MIDI
Bank 3, (which is PC3K bank Orchestra ), for example, is 430 Lead Oboe . The MIDI Bank
parameter displays which bank the current program is assigned to, and automatically changes
to match the Program value you set.
You can send Bank Select messages to external MIDI devices as well, by setting the Destination
parameter to a destination including MIDI or USB_MIDI , then changing MidiBank. Some
instruments may have more banks than the PC3K. Bank switching via MIDI makes it easy for
the PC3K user to select sounds on external instruments, no matter how many banks they might
have.
When you change the value of the Program parameter, the value of MidiBank automatically
changes correspondingly. If you want to transmit a MIDI Bank number different from the one
corresponding to the local program, select the local program first, then change the MIDI bank.
If you select an empty bank (like Bank 53), the zone will still produce sound on the PC3K,
provided that Destination is set to a destination including Local . The Program parameter will
display whatever internal program you set, but the bank number transmitted over the MIDI Out
port will be different from the internal program’s bank number.
