Revolve is a non-linear approach to MIDI sequencing, with a vintage synth style layout, with two bassline modules, and one drummer, like 2 303's and a 909. With Revolve, you can program your synths and or soundcards like ReBirth, only the sound pallate is limited only by your synths and samplers! Just import a ReBirth song, tweak, tweak, tweak, and away you go! Visit the website and download the demo for more
