hello pierre,

1. rectification of a waveform is possible with an
a110 and an a133, but that depends on the waveforms used.
when the signal is negative, the cv has to be negative too
to get a positive wave at the output. that can be very
complicated when you use different waves for signal input
and cv input. from my experience rectification works better
with an a172 max/min and an a175 inverter.

2. sometimes i play polyphonic sounds on the a100 and
i recommend the mcv24 interface for that. it has very cool
polyphonic modes which make it a snap to set up a
four-voice patch for instance. you should download the
mcv24 user manual for reference, everything is explained
in there.

best wishes
