Zoom B3 monosynth - what is this modelled on?

[la bam]

Pretty much as the title - does anyone know what the mono synth on the zoom b3 is modelled on?

If its just a generic synth - are there any individual pedals like this?

Zoom aren't particularly coy about what their various amps and effects in the B3 are modelled on so if the Monosyth doesn't say, then I doubt that it is based on anything specific.

Besides with only waveform, filter envelope decay and resonance available to adjust, any synth or pedal with these parameters should do a close enough job.
