Modulation Overview
The PRO-12 ASB has three modulation sources: LFO, filter enve-
lope and oscillator B. These can be individually or simultaneously
routed to five different destinations - oscillator A frequency, oscilla-
tor A pulse width, oscillator B frequency, oscillator B pulse width and
filter cutoff.
The LFO has its own dedicated modulation buss which is controlled
by the mod wheel - the LFO modulation destinations are selected in
the 'Wheel Mod' section. The 'Poly Mod' section has controls for
routing the filter envelope and oscillator B modulation sources to
any or all of the five destinations - the modulation intensity is adju-
sted manually for each source. When 'Poly Mod' is in use, pushing
up the modulation wheel adds to the overall modulation depth. The
filter envelope and oscillator B are polyphonic modulation sources,
which means that they act upon individual synthesizer voices; the
LFO is a monophonic source which modulates all voices globally.
Wheel Mod
The modulation wheel controls the intensity of the 'wheel buss' LFO
modulation. In the origi¬nal synthesizer, this was the only way to
control the wheel buss, but the PRO-12 ASB has more advanced
options, including additional controls for overall modulation intensi-
ty and modulation offset. (Pitch bend range can also be program-
med now - you will find these controls on the 'Add page' of the
Remote Software.)
LFO / Noise source mix
This control allows you to blend noise in with the LFO modulation -
higher settings introduce more noise!
