the tone modulation is a no go, i still need to work with the gain modulation (sync to the lfo).
Yes the sequencer (5 steps sequencer with option to select 3/4/5 steps) is modulating the main LFO tap ratio (the one that sweeps the volume to create tremolo, ratios are x1, x2, x3, x4 or x8 of the original tap). The sequencer will run in 2 forms, manual you press a footswitch and it will advance to next step or it will be always running advancing through the steps (based on the same frequency of your tap x1)
Option to add another LFO that will modulate the mix (so its like a tremolo inside another tremolo), this lfo will be also running on the same frequency of your tap, but you could change the wave, but the amount will be full so it will go from no trem to a complex trem pattern (depending if you also have the sequencer going).
I added this image so you have a better idea: imagine the sinusoidal carrier is your trem sound (running x4 of the tap based on the sequencer step), the baseband signal is the extra lfo (running x1 by default of the tap and also as sinusoidal wave). The amplitude modulation will be the output soundwise, a trem that is running into another slower trem. But if you start playing with waveshapes and adding the sequencer you could go into a new
