Not so. The LFO is presumably voltage controlled and you can also 
generate a downward ramp signal that can be synchronized to the tap? 
Just S&H the ramp at each tap before you reset it and make a moving 
average of the last few taps. Synchronize the LFO too if you need it. 
The rest involves some scaling of the control voltages and figuring out 
how to keep the CV constant when there is no tapping.
