This is an explanation on how I achieve the “cello hack” using a Moog Mavis and an Electro-Harmonix Oceans 12 Dual Stereo Reverb pedal. The Mavis is mounted in a NiftyKEYZ Eurorack keyboard / enclosure and I’m using the NiftyKEYZ “aftertouch” output to control the Mavis’ LFO rate. This allows me to get a more realistic vibrato by varying pressure on the keys. Harder presses = faster vibrato.

Another “classical music” composition. Using the Moog Mavis analog synth module mounted in a NiftyKEYZ Eurorack keyboard / enclosure. The NiftyKEYZ aftertouch is controlling the vibrato which is why you see me pressing the keys so hard, LOL.
