This along with its sibling West Pest are very powerful desktop synths that go well in any modular setup. They have many modules/functions in one compact unit. The East Beast is a subtractive synth with a good sounding VCO, a very nice filter along with the usual VCA/LFO/Envelop setup. The only downside to this is the envelope which are quite bad. The are either very short and click or longer and sloppy. It is impossible to get a good snappy envelope out of it and I usually use the envelope from it's built in Multi Function or even an external envelope. Apart from that it does a lot for very cheap compared to how well made it is. The best feature of it, in my opinion, is it's filter which is very nice.
