Hi, I open a thread to master the dsynth engine which is a multi envelope dual oscillator synth.
Thanks for your remark/feedback.
1 - Understand the concept of multi envelope :
Envelope crossfader parameter work with decay parameter to define the final envelope for each oscillator.
Envelope crossfader parameter define for each oscillator the envelope type in decay section and the envelope amplitude (not envelope volume) → there is no envelope modulation if crossfader parameter is a line (the OSC sound is continuous)
Note : grey line is OSC 1 and blue line is OSC 2 (I thought the opposite)
2 - Understand the concept about dual oscillator (I’m not a specialist. I’m a simple OP-1 explorer)
Before talking about cross modulation, let’s talk about the “frequency” parameter of OSC 2.
The mix of 2 waves with d-synth makes it possible to obtain the analog synthesizer effects.
I don’t know why TE put an M and the values 0,1 because in fact this parameter determines the OSC 2 pitch from 0 to -4 octaves compared to OSC1 pitch.
Here are the values that I have chosen to make a playable sound (in notch starting from the octave 0) :
0 - OSC1 and OSC2 are in the same octave : sound clean
I think the filter itself is just a resonant band-pass with wide Q-value. The setting at 11 o’clock simply corresponds to frequencies oscillators normally generate around 0 octave. However, its knob value seems to be also tied to something else.
D-Synth is crazy. TE should post some definitive info about about it.
Totally missed this. This is a very good feature. Might not seem like it, but some values of the mod parameter (red) make the whole DSynth sound totally different and they weren’t accessible before except with LFOs.
