Synth Only

Synthesizers and nothing else: no piano section to fall back on, no organ, no sample library pretending to be an orchestra. These are instruments whose job is to make a sound from oscillators, filters and envelopes, from single-purpose desktop modules to five-octave keyboards. Compare the engine and the voice count first, then the keybed, the multi-timbral parts and the connections. Boards that also do pianos and organs are in Multi-Function Keyboards, and plugins live in Software.
