Hello Ken.....and all. Sorry Ken...You must HATE me always jumping in
like this BUT!!!! This is NOT a Sawtooth FREQUENCY shifter circuit.
It's a Sawtooth PHASE shifter circuit. I can already hear people
writing in "I built the thing but the frequency doesn't change when I
sweep the voltage. What am I doing wrong?"
This circuit idea; if my memory serves me, was published in
Polyphony magazine back in the 80's.
On a side note I'm working on the "Mother of all" Analog sequencers.
CPU's, MPU's and PICS need not apply yet it'll do swing like an 808,
tied notes ala 303 Glide, random, up/down, variable note legnth and
gate time PER STEP, and will be expandable from 2X16/4X8 up to almost
any size (two 4 rack space cabinets will house an 8X16/16X8
sequencer).
I'll keep everyone posted as it progresses.
