i poked around to get a stripped down synth in JSFX and
finally i got the ownsynth.jsfx
and the then ownsynth II that has a chorus
a version with sine, saw, tri and square waves, filters (hipass & lowpass,
each with resonance) and an sub for adding lower octaves
and a sup for adding upper octaves and a dialable pitchbend range and a clipper
and selectable channel count making it somehow a mono or poly instrument
as mono it has a un-nice release, as poly you get one osc per note and time
those effects (hi lo pass..) will also run without the waves,if anyone needs such stuff in mono
a demo using this last version is here (tilr made the drums and reaverbate the reverb)
or this with more filtering, drums are from a looped sample

and a demo using the ownsynth II


and then i made two fixed value choruses (think of the technical implementation in the Roland Juno's)
i bet mine are sonically far away from those
chorus_I
chorus_II

a demo using those



a reapack repo index containing this is here or here


more about the synth



this video shows twiggling the synth's parameters and the result as oscilloscope visualisation and audio

the synth was played with a single midi note. to get something more valuable you will
have to deal with midi note length, parameter modulate the filters , add rooms with delay
reverb and colour with chorus and others... bla...




a demo with the first version(very little pimped with reverb and delay)

and one with the filterwise better version, slightly pimped, drums from tilr
