B-400 is a simple synthesizer that provides a myriad of minor tonal variations to a core sound that falls somewhere in between an electronic piano and a basic poly-synth.

B-400 utilizes three oscillators (with 32 waveforms each) as well as a leslie / vibrato style flutter output plus two other main output channels - one being a simple clean out and the other a tube simulator with a 3-Band EQ. Each oscillator is able to be coarse tuned.
