VIDEO Reference Simple Synth Tutorial Glitches
Just went through the beginner synth tutorial to see if there was any useful info, most of the versions work and sound fine, but the very last version was silent in its default state, and I ended up verbatim copy pasting to see if I had gotten anything wrong, the attached video link shows copying the code from the packaged CabbageManual/docs/beginner_synth/index.html and the resulting initial silence, and then it seems that no matter what I adjust, the LFO applied to the cutoff of the filter in this way either bottoms out the cutoff frequency to 0, or if the LFO is bipolar it could even be causing a negative value multiplier to the kCutOff:
kLFO lfo 1, kLFOFreq aLP moogladder aOut, kLFO*kCutOff, kRes
I think one thing that could help is to scale and add the LFO value to the cutoff, and possibly even clip or tanh softclip the values if that is possible. This could require another knob or two, Ill try some things and see if I can fix it and post a fixed version here.
I think this is an important fix to consider, if I had gone through this tutorial in my initial evaluation, I may not have felt like Cabbage was a solid route for development, even though the solution is potentially rather simple.
Looks like this has been mentioned in a couple threads:
