Master Volume
This slider is not programmable. It does exactly what you think it does: set the level for both the
main outputs and the headphone output. It does not generate MIDI Volume commands or any
other MIDI data.
Panic
Pressing the Panic button is the fastest way to get all sound, both within the PC88 and in any
MIDI devices that it is connected to, to stop. It immediately releases all notes in the PC88, plus it
sends the MIDI messages ÒAll Notes OffÓ and ÒReset All ControllersÓ on all 16 MIDI channels
to the MIDI Out jack. If you hold the button down for a few seconds, it additionally sends out
pitchbend resets (pitchbend value of 64), and note-off commands for every note on all 16
channels (thatÕs 2048 note-offs, in case youÕre counting). Panic is your friend. It can be used to
reset your entire MIDI setup to a known state, if you ever need to do that (which can happen
pretty often with a complex setup). If you Þnd yourself stuck in MIDI Purgatory, and notes that
you donÕt want are sounding from who knows where, the Panic button can even save your life
(and your audienceÕs ears).
Effects
The three buttons in the Effects section allow you to switch among several combinations of
effects. The Þrst button selects the type of reverb: pressing it repeatedly toggles through Room,
Stage and Hall reverbs, in order of increasing reverb time and level. The light indicates the
current setting. Press the button yet again, and no light shines, indicating that reverb has been
turned off. The second button controls the tone of the reverb: Bright emphasizes the high-
frequency components of the reverb, for simulating a room with hard surfaces; Normal plays
the reverb ÒßatÓ; and Warm emphasizes the low frequencies in the reverb, for simulating a
room with soft surfaces, such as furniture or curtains. When the Þrst button has shut the reverb
off, none of the tone lights will be lit.
The third button selects the chorus or delay effect. It has four choices: Chorus 1, which imparts
a two-voice chorus onto the sound; Chorus 2, a more complex four-voice chorus; Delay, which
produces an echo effect; and off. The settings of the reverb and chorus/delay controls are
independent of each other, and one can be used freely with or without the other. If you change
the settings on an Internal Voice, the change is remembered, and the new settings will appear
every time you call up that Internal Voice. Similarly, in Setup mode, the effects settings are
automatically stored along with a Setup when you perform a Store operation. Besides these
simple adjustments, there are many more ways to modify the effects in the PC88. See Chapter 7
for details.
