2-11 MODULATION SECTION
This panel is the one most likely to confuse beginners. After a few hours practice,
however, it should become second nature – especially if you repeat this mantra!
“3 sources via 2 paths to 5 destinations”
MOD FIL ENV, MOD OSC B and MOD LFO knobs: The amount of modulation mixed
into the WHEEL or DIRECT paths. The depth of modulation routed into the WHEEL
path is controlled by the modulation wheel (MIDI CC#01).
WHEEL | DIRECT switches: These route each of the 3 sources into one of two busses:
the so-called WHEEL or DIRECT paths.
OSC A FREQ, OSC A PW, OSC B FREQ, OSC B PW, and FILTER switches: The vertical
row of switches select either the WHEEL or DIRECT path for each destination.
Note: In the original hardware the signal at each PW input gets inverted – when the
modulating signal goes up, the pulse width goes down. We decided to keep this quirk,
so if you want to compensate for deep modulation by adjusting PULSE WIDTH, you
need to compensate in what seems to be the wrong direction!
