Master Mode
MIDI Receive (RECV)
When you're in Program mode, and playing a KB3 program, you may want to leave
LocalKbdCh set to None, which is its default value. In this case the MIDI Controller messages
for KB3 control listed in Table 6-2 on page 6-8 are certain to work (if you haven't edited the
Control Setup, see The Control Setup on page 7-68.) There are some possible disadvantages to
having LocalKbdCh set to None. First, the PC3LE doesn't relay incoming MIDI to its MIDI Out
port. Perhaps more importantly, if you change the channel on your MIDI source, the PC3LE
plays the program on the channel used by your MIDI source—regardless of the PC3LE's current
channel. For example, if your MIDI source transmits on Channel 1, and you set the PC3LE's
current channel to 2, you'll still play the program assigned to Channel 1. If that's the way you
like it, there's no problem.
You may find it more convenient to use the local keyboard channel. In this case, the PC3LE
remaps incoming MIDI to the PC3LE's current channel, so in Program mode, you'll always play
the program on the PC3LE's current channel. Incoming MIDI also gets sent to the PC3LE's MIDI
and USB Out port. On the other hand, in this case your MIDI source's transmitting channel must
match the PC3LE's local keyboard channel for anything to work. Furthermore, for KB3
programs, some of the MIDI Controller numbers listed in Table 6-2 on page 6-8 won't
necessarily work.
Things are a bit different for playing setups. In this case, you must use the local keyboard
channel to be able to play and control all of the setup's zones. Set LocalKbd to match the channel
your external MIDI source is using (if for example your MIDI source transmits on Channel 1, set
LocalKbd to 1). All MIDI information that the PC3LE receives on the local keyboard channel gets
remapped to the channels and control destinations used by the zones in the setup.
The PC3LE also remaps certain MIDI Controller messages that it receives on the local keyboard
channel, so that they correspond (in most cases) to the default assignments for the PC3LE's
physical controllers (Mod Wheel, knobs, etc.). While this ensures that the physical controllers
work in a consistent and relatively standard fashion for most setups and V.A.S.T. programs, it
necessitates a few adjustments to make incoming MIDI Controller messages control the KB3
features listed in Table 6-2 on page 6-8. Without these adjustments, some of the KB3 features
won't respond to MIDI Controller messages—this is true when you're playing programs as well
as when you're playing setups.
To make everything work properly, you need to make sure that all the appropriate physical
controllers are assigned for KB3 control. Physical controller assignments are handled by setups,
and are defined by parameters for each controller on the Controllers page in the Setup Editor.
Each zone of a setup has its own controller assignments. Programs don't have controller
assignments, so they "borrow" them from the Control Setup. You can read about the Control
Setup in detail on page 7-68.
When you're playing a setup on the local keyboard channel that uses a KB3 program, each zone
must have the appropriate physical controller assignments in order to control KB3 settings (see
Set Controls KB3 (KB3CTL) on page 7-65.)
