A realtime software synthesizer with filters, effects, envelopes.

Do you need good lead lines in your production? A synthesizer, biting hard or teasing soft? A synthesizer, flexible to bend to any kind of synth sound? JellyFilter is the solution.

JellyFilter was copied from a red Swedish lead synth idol (which is available in 3 versions to my knowledge) and implies some more functionality, at some point less functionality.

Actually this is the first release, but it was build using technology and experience gained in a freeware DSP synthesizer, that was created by as well.

Technical details:

Polyphony / Timbrality:

4 voices per channel, 16 channels.

2 Oscillators with Controllable Unisono per Osc: Saw, Sine, Square, Pulse with PWM, Noise


24dB LowPass and Bandpass with resonance, Highpass, envelope amount and cutoff, possibility for self-resonance (protect your ears)


ADSR for the Amplifier section, ADSR for the Filter section.


Portamento, Distortion, FM OSC 2-> OSC 1, Sync Osc 1 to Osc 2


Attack Decay Envelope: Either to FM amount or to OSC 2

LFO: to OSC 1+2, to OSC 2, to Filter, to PW

07 July 2007: Alpha version of JellyFilter v2.0 available

I kept back the binaries of the polyphonic C++ version quite some time now, lying untouched on my Laptop if I don't have time and sometimes working on it as I have some leasure beside family and work.

Since within a reasonable time the product can not be brought to a "perfect" state I give out the binaries for the alpha version for the following reasons:
# The product works and it is mainly the UI that needs finishing
# Filters need some enhanement
# the remaining 30% need 70% of the effort (management rule)

So as of now I am working on making it beta.
