[sdiy] Re: reset circuit for LFO

unfortunately there is no reset on it. This was a major design flaw...
the lfo is great except for this important factor (and has caused many
people to sell theirs as a result). Also there are jumper switches on
the back of the pcb for selecting the 2 x 4 sets of mod source/dest
for the sum/diff/max/min outputs. As a result I am making a 4HP
expansion module that has two resets, selector switches and I may add
jacks for external signal ins (so you can route other things through
the max/min/sum/diff circuits)
