Flexible multi tool for a great price

UglyKidJoe, 25.05.2014
The A-171-2 is based on the CGS75 from Ken Stone which is itself a licensed adaptation of the Serge DTG/DUSG and is licensed from both therefore the higher price in comparison to other Doepfer modules. As a multitool it can be used for various tasks apart from the obvious slew generation: LFO, Envelope Generator, Low-Pass-Gate, Envelope Follower, VC Pulse Delay, Sub-Harmonic Generator or Oscillator (not recommended for playing notes though as the tracking is not exactly 1V/Oct).
Apart from the exp/lin switch the curve can also be set with the CV pots when nothing is patched in their input jackets. It then works similar to the log/lin/exp pot of the Maths from Make Noise which is very handy for setting subtle responce characteristics.
Beware that in the standard configuration it outputs only +5V which you can set with a trimmer. So modules needing more juice might sound different or filters might not completely open. E.g. this is important when combining the module with Make Noise or Malekko modules. In this case set the trimmer appropriately or use an external amplifier (a real amplifier as most VCAs are just attenuators).
I also own a Maths but prefer the A-171-2 as an Envelope Generator because in my opinion it sounds better with more snap. Might be because I'm using Doepfer VCAs (A-131-3 with the CEM3360). It's also easier to use attenuated CV on the A-171-2 because you have to patch another channel (2 or 3) of the Maths (or Function) to get CV attenuation and as the cycle swith is a mechanical switch it's state doesn't reset when powering down the modular.
