<DIV><SPAN class=330023822-08102018><FONT color=#0000ff size=2 face=Arial>Today
I made a PCB for a Polymoog resonator with voltage-controlled corner
frequencies. I put four resonators on the board. Three of them I am
going to stuff so that the manual range of frequencies are the same as the
original Polymoog (60 to 300 Hz, 300 to 1500 Hz, and 1500 to 7500 Hz).
However, the fourth I'm thinking about setting up so that it can scan over that
entire range, so that it can cross over and reinforce each of the three peaks
from the other resonators. Does anyone have an opinion on this idea?
If so, I'd love to hear it. Maybe it would be better to break the audio
range up into four ranges. I can't decide.</FONT></SPAN></DIV>

<DIV><SPAN class=330023822-08102018><FONT color=#0000ff size=2 face=Arial>Also,
the 300 to 1500 Hz resonator and the fourth resonator will have their BP outputs
inverted, and these inverted outputs can be selected with SPDT switches.
Finally, the HP/BP/LP outputs for each resonator will be routed to DPDT On-On-On
switches, so that the modes can be summed in any
combination.</FONT></SPAN></DIV>

<DIV><SPAN class=330023822-08102018><FONT color=#0000ff size=2 face=Arial>I fit
the whole circuit on a 4" x 4" PCB. I think I'm going to make a panel PCB
that's the same size so I can just bolt them together at the corners, although
there will be a bunch of wires connecting the two. I should have this
thing up and running by the time I go to bed tonight. I'll probably try to
make a video.</FONT></SPAN></DIV></BODY></HTML>
