PC2 Version 2 Operating System Software
Bug Fixes Since Version 1.0
MIDI Controller 6
Some programs (like 090 Meteor Strings), use MIDI Controller 6 to control program features. In
Program 090, for example, it controls Lopass Filter resonance. When you select this program, it
sounds the way it does because the program contains an initial value for MIDI 6.
Prior to Version 2, putting this program (or any others that had initial values for MIDI 6) into a
setup sometimes affected the sound of that program. That's because the PC2 uses MIDI 6
internally to control other setup features. In the case of Program 090, the difference was extreme
because much of the program's sound depends on filter resonance, and putting the program
into a setup would change the filter resonance level.
With Version 2, putting a program into a setup no longer affects the initial value for MIDI 6 in
that program (regardless of what it's assigned to control), so any program that uses MIDI 6 to
control a program feature will sound the same whether you play it in a setup or as a single
program.
Portamento Time
MIDI Controller 5 (Portamento Time) now works properly—that is, higher values cause the
portamento to occur more slowly. Prior to Version 2, the PC2 had the opposite response.
Program 081 Vox Lead
This program, which is monophonic, had problems when Layer 4 was enabled. This has been
fixed. This fix was first introduced in Version 1.5.
SysEx Dumps
In Version 1.0, SysEx dumps would occasionally be disabled if the PC2's available memory was
low. Now SysEx dumps work regardless of how much memory is available. This fix was first
introduced in Version 1.5.
Treble EQ
In Version 1.0, the maximum boost levels for Treble EQ were inaccurate—that is, a setting of
+11 dB or +12 dB didn't actually boost the treble band by exactly that amount. With Version 2,
the levels have been adjusted to correspond to the display values. This fix was introduced in
Version 1.5.
