QEX

The QD's expander, in 4 HP, joined to it behind the panel. It adds two outputs, 3 and 4: the four voices can each be sent to their own output, mixed like a car radio's four speakers (pan left and right, fade front and back), or fed a second stereo mix before or after the main levels, with its own EQ and compressor. Four more CV inputs and four more LFOs, assignable like the QD's; CV 1 and CV 2 can also take a clock for fills and ratchets, fire decay envelopes or trigger all four voices at once. Four more LED buttons fire the voices and select them.
