Yes, that’s true. The pattern generation controls aren’t very conducive to acid bass lines. It’s a bit better at early Autechre or Nils Frahm.
The arpeggiator does have a few baseline patterns, but they are not a replacement for a 303 style sequencer.
If there’s enough demand, I could create a separate module that provides a more typical control system (cv/gate input), with no quantizer, effects, internal clock, or pattern generators? It would be just the waveforms, v/Oct, gate input, sub oscillator, vca and filter decay, filter, cutoff, accent, and glide controls? Kind of “bring your own sequencer”? But I think that already exists, here: The Acid Kit: new modules for the Rack x0x crowd!
Another option is to find the arp_patterns.json file in the voxglitch devices resource folder, under the “data” sub-folder. You could hack in your own library of 303 style patterns to replace the existing arpeggios.
One thing that I could do is update the documentation with a visual representation of all the “factory” arpeggios. In fact, let me see if I can get that done right now.
UPDATE: Well… the visualizations are pretty “modern art”, and not as useful as I would have wanted. but they’re neat in their own way. You can see them at the bottom of the documentation here: voxglitch/docs/modules/centralics/user_manual.md at master · clone45/voxglitch · GitHub
