I use the A156 quite a lot to create arpeggios, using LFOs through a
mixer for attenuation and the CV Source module to supply an offset
voltage. Its a very useful and fun module, I highly recommend it.

For keyboard-style arpeggios, where you play a chord and get a
resulting arpeggio, the only A100-based solution that comes to mind
would be to use an MCV24 to extract the individual note CVs from
the chord, and patch them to the A155 external inputs for
arpeggiation. The A156 wouldn't be needed in that patch, since the
midi notes would be already quantized.

I suppose you could do the same thing with a polyphonic CV keyboard,
if one exists.

I mostly use my Waldorf Pulse for keyboard arpeggiation, either
driving itself or the A100.
