Odo from Odosynths is well known on the DIY synth forums especially
the SynthEdit forum. A heavy synthedit user he has just released all
his softsynths for free. Odo was already very generous giving away a
lot of synths, drum machines and processors but he has decided to
release all his softsynths for free.

The one pictured above, the Double Six XXL, is an FM synth with 32 possible
6-op or DX7 style algorithms and 16 4-op algorithms. Even a cursory glance at
the interface lets you know that this is a well functioned synth. 11 different
waveforms for the operators, clipping/distortion/overdrive & and LoPassFilter
on each operator, 19 LFO shapes, 8 and 14 stage envelopes, multimode filters,
throw in a few sequencers and you get the gist…. FM on steroids.

Stoq is available as a freeware VST instrument for Windows PC. Download it here (1.35 MB).

xoxos Stoq
xoxos Stoq – suited for synthesis of maracas and other shaker instruments

xoxos explains the model:

impulse is driven by ‘pitch’ which is a % for event per sample at oscillator pitch. tracking is implemented but architecture is geared towards percussion synthesis.

the event % is shaped with a ‘rise’ envelope that lowers the chance for events to immediately follow other events (ie. hysteresis, good for emulating ‘larger beans’). when rise is locked to pitch it can be shifted by +/- 2 octaves. ‘tail’ multiplies the % after the rise period to reduce longer gaps.

impulses are decay-stage enveloped and consist of either the envelope contour or enveloped noise, low pass filtered for dynamics performance, then routed to a bank for 5 bandpasses (# of bands can be reduced to save cpu).
