one thing I always wanted for the MD was a LFO quantizer:
the first encoder of the MC increases the LFO time by a value of 2,4,8 or16 (custom)
second encoder increases by a value of 3/6/9/12 for example
third encoder increases by 4/8/16/32
and fourth encoder could either increase by 5/10 etc, or be used to double the times of the first three encoders, so that is encoder 1 is set to increase LFO time by 2 values, turning up ecoder 4 one notch means encoder 1 now increases LFO time by 4 values per notch.
This way you could create and play the lfo's rythmically and change easily from lfo time of 2 to 24 without messing up the flow of the LFO
Oh my, I'n not good at explaining things here
