Re: [Doepfer_a100] Modules for acoustic instrument processing

Have alook at http://www.doepfer.de/a100_man/A161_man.pdf
Page 8 contains an example for the usage of A161 with A131 as a sequencer.

The A-151 would work similar, but to achieve the same effect you have to 
feed a constant voltage into the common i/o of the module. You will get 
more variations if this is not a constant voltage but a LFO or some 
quasi random stuff (like LFOs in the audio range or VCOs).

Then the A-196 is the right choice: terrible pitch tracking at its best.

That is right. Especially if you use the VCO-out as modulation source 
for a high resonating VCF (can create some "talking" sounds).

ok, AS does not have a S&H + Slewlimiter as combimodule. But others that 
are interesting:

The A171 slewlimiter is definitely recommended over the A170, because of 
its usability in connection with the PLL A-196 (too complicated to 
explain now).
