The Volca units come in three flavours, Beats (an analogue/digital drum machine), Bass (a three-VCO bass line synth) and Keys (another three-VCO synth, but with alternate voicing options, including pseudo-polyphony). the first of which to grab our attention was the Bass. Essentially, this is a hybrid unit; an analogue sound engine with digital control so dial tweaks and note info can be recorded into the sequencer/accessed over MIDI. Volca Bass was designed in Japan and built in Vietnam and has a ‘full analogue signal path’.
According to several user reviews, they have praised Korg Volca Bass for the sounds as good as more expensive analogue synths; Super compact, well built, can be battery powered; Individual waveform selection and subtle detunes; Excellent three-part sequencer. Also, some users have complained it for no accent or motion control; No way to automate filter cutoff/resonance.
