2 filters in parallel
« on: August 08, 2017, 11:18:05 PM »
hi xavier,

would it be possible (codesizewise) to have two filters in parallel (not serial) at the output stage? the second one could just be fixed to bandpass mode. if you set first filter to lowpass and second to bandpass you can get formant vowel sounds, which work well with fm sounds.

Hi,

That would require some changes, but why not..
The FX are implemented here :
https://github.com/Ixox/preenfm2/blob/master/src/synth/Timbre.cpp#L491

A solution that should work without modification, is to have all instruments with same preset and listening to the same midi channel.
Set a different filter for each instrument.
You'll get 4 filters in parallel, but with limited polyphony.
