nice and concise mixer.

Henri aus B., 12.02.2014
this mixer works as you expect, but some minor addition would make much more useful.
for instance some leds to monitor the in and out, and having knobs with a center "click" so that you know you are at the zero position.

also after playing with some make noise module i tend to miss their cleverness. for instance when you unplug one input of such mixer on a make noise, it becomes an offset source, which comes really handy in many cases.

that said, the module follows the doepfer philosophy : make one thing at a time, with a clear and simple approach. in that regard this module is a prefect match !
but i would recommend also looking at other makers of modules that might have complete/complex product.

Good for CV, bit less for audio

30.03.2015
This module handels cv signals very well, but mixing audio signals is pretty hard.
At the moment I need to, but the problem is that the zero-point is very hard to find, so quickly muting channels is a bit hard.

But the module handels CV very well. It could even actually be seen as an improvement on the offset generator as the first knob can be used as a voltage offset, while the other 4 inputs can still be used to generate offsets and be combined to complex patterns for note-sequences or modulations.

After 1.5 years still no crackles or noises..
