Beast is one fat sounding synth! It really can sound very much like true analog. Yeah, it's monophonic but it's obviously meant for rythmic basslines or leads and in this deparetment Beast shines. You can get really thick and dirty using the distortion or do clean pulsing warm basses. The built in reverb and delay are an added bonus but aren't the best in the world though they get the job done. Beast is very stable. I've only found one instability and that's a crash when you change sample rates while Beast is active. The included manual explains all the details of the synth. Overall I love this thing for it's great sounds. I've been using it a lot lately in a new song and for only $29 this synth is a steal!
