|3~4.8 MG
I________________________________________________
The Modulation Generator (MG) is a low frequency control
oscillator used for regular, cyclic modulation of DCO pitch and
VCF cutoff frequency. The MG can be used for vibrato, growl,
automatic wah-wah and other “ repetitive” effects. MG effects
can be programmed into a given sound, added during per
formance with the Joystick, (or by external devices via MIDI),
or both.

8 ■' FREQ
Frequency determines the speed of the cyclic varia
tion in pitch or tone quality (vibrato, wah-wah, etc.).
Frequency has a range of 8 - ; the higher the
value, the faster the speed.

S c' DELAY
Delay determines the delay (if any) between the time
when you play the key and the time when vibrato, wah-
wah, etc. begins. Delay has a range of 8 - IS .
With a value of 8 , the effect begins as soon as you
play the key. The greater the value, the longer the de
lay before the effect begins. (Depressing additional
keys while holding one or more down does NOT retrig
ger the delay function.)

| 3.4.9 MIDI
MIDI is a data and protocol format for control and communi
cations between synthesizers, sequencers, rhythm machines,
and personal computers. (See page 31 for more details.)
Although you are free to set all parameter values as you like,
MIDI 85-88 parameters can not be given particular values for
particular programs. MIDI parameters will remain the same
regardless of which program you select. If you change a MIDI
value, that new value will then apply to all programs in memory.
Note that parameter 85 (RCV CH) and 87 (BEND) values can
be saved along with program data and loaded from tape to
internal memory. However, parameter 8S (PROG CHANGE)
and 88 (SEQ CLK) cannot be saved to or loaded from tape.
