Trying to get a piano-like sound out of Minibrute 2s. Not sure if it is like a piano but with a Desmodus Versio module it sounds sweet anyway.
A mono analog synth has no hammers or strings, so a piano-like tone needs a sharp attack, a fast decay that leaves a quieter sustain, and a filter that closes as the note fades. The Noise Engineering Desmodus Versio, a stereo Eurorack reverb, does the rest by adding space and a bit of body.
The same piano idea is in Almost Piano. More Desmodus Versio on its tag.
