Voltage controlled output mixing
Four of the single outputs of the A-188-2 are patched to the
audio inputs of a voltage controlled mixer A-135-1. The four
control voltages of the A-135-1 are used to define the levels
of the BBD taps.
Even the Karplus/Strong patches described in the A-188-1
user's manual can be realized with the A-188-2. The mixed
outputs of the A-188-2 lead to more complex sounds
compared to the A-188-1.
