the lfo rate changes w/ your tempo. i think maybe at like 12.5% lfo rate you get one cycle per 4 rows. i use it sometimes to make up for renoise’s low resolution tremolo implementation.
Yes you mean negative modulation, or reversed phase, or whatever…? Nowadays you can only make upsaw LFO while downsaw is also often needed. And LFO (re)triggering with wave offset would also add much much much to toy with . Like you could choose where on wave the LFO wave starts. Could be included to LFO reset command, like x600=beginning, x67f=half wave and x6ff=end of wave.
a quick research:
On speed 6:
~0.75%=~80 rows
~1.55%=~40 rows
~3.15%=~20 rows
~6.25%=~10 rows
On speed 3 the rows are doubled. Nor perfectly accurate, but closest you can get (easily, if anyone is interested to make mor accurate research, then be my guest)
You can guess the rest…
