DavoSynth is inspired by Davolisint (a rare Italian keyboard created in 1972). It shares the same architecture as original, which lacks most of the features we'd expect from even a basic synth. There are two oscillators called VCO1 and VCO2 - but there are no waveform selection, syncing options or envelopes. So, what do we have? One Portamento and fine tune per oscillator and the heart of the synth - four sliders with vibrato effect and 7 different footings available at the same time (32', 16', 8', 4', 2', 1', and 1/2'). There's also a lever called "extend" which is an up-only pitch bend, not unlike the Yamaha CS-01 for example, as well as chorus and delay effect.
