Re: Amplitude and Frequency Formulas for RAMP LFO
aha
then k is repeat RAMP in float 0..1
k = ramp/range;
and compc = 1.0 - k
XFADE also in area 0..1.0?

Re: Amplitude and Frequency Formulas for RAMP LFO
As I understand RAMP LFO in fv-1 : Every sample we increment LFO_ACC to some step value step = freq / 16384.0; mask = RANGE - 1; LFO_ACC = (LFO_ACC - step) & mask - this is just for simplicity from sign of step depends type of ramp : decreasing or increasing so we get difference rates for differ...

Re: Amplitude and Frequency Formulas for RAMP LFO
CHO RDAL for RMP looks like triangle (float 0..0.5)
If we look on phaser sources and listen - we hear that lfo work smooth like periodic function, RMP have clicks every period.
