Renoise’s modulation is awesome for sound design, it is so versatile, unfortunately the LFO stops at 20Hz and is always triggered. Here’s some suggestions:
Tuned VCO modulation
Extend LFOfrequency range to audible range
Free running LFO option (not triggered by note on)
Noise Modulation (With color dial)
PROTIP: You can already fake these features by adding an operand to the modulation, link the operand to the macro and then hand drawing the modulation in the automation editor. The engine handles it smoothly with low CPU usage. It’s just an unfathomable awkward process.
