Anyone built the Commonsound/4MS Stereo Panneur?

[theundeadelvis]

I'm looking for a panner that will do a very hard pan from channel to channel. Something that will do almost a complete on/off of the channels. Basically I what I want is one channel to just completely mute and the other channels instantly comes on. No fading from one to the other (not sure if that makes sense, a squarewave maybe?). Will the Commonsounds panneur do this? Any other options out there? Thanks as always!

Yes, and it does what you want. Like all optical tremolos, it loses a certain amount of the hard chop at high speeds, but at low to medium speeds it's very choppy.

Awesome! Thank you very much Taylor.

I have one. I run my rig in stereo, and it's FANTASTIC. The split chop tremolo can get almost surreal. A great piece of kit.

Cheers,

Hi,
I'm breadboarding and experimenting with a Stereo Panneur, but having problems getting the inverted LFO signal right:
The synced OpAmp of LFO2 works fine in Stereo mode, but not in Pan mode.

STEREO MODE (SYNC=on, PAN=off) -> When using the non-inverting input, the LED is exactly identical to LFO1 LED; nice and bright at peak, dark at other end. Sounds great and clear.
PAN MODE (SYNC=on, PAN=on) -> When using the INverting input, it's doing the opposite of LFO1, but it's way less bright (and seems to take a bit longer to discharge and darken). No sound comes through.

So, I've tried several things:
1) Adjust the gain of the synced OpAmp (the 2x 1M resistors), which increases the brightness, but reduces the smoothess and makes it always go choppy/square.
2) Adjust the 2x 100K resistors of the voltage divider at the non-inverting input, which 'offsets' the middlepoint of the LED brightness.
Kinda works, but once 'brightest' is equal to STEREO mode, 'darkest' isn't dark enough anymore.
3) blending in some V+ directly to the LED. Obvisously doesn't work, as it increases the brightness AND the darkness the same level.


Anyone suggestions?
Anyone who built this (or other inverting stereo LFO thingys) successfully?

If I can't get it to work, I was thinking of adding a seperate inverting OpAmp to fully tweak the signal, then just switch to that for the synced panning function...


Thanks a lot in advance! Beers for the winning tip!
