Does any one know of a way with current modules to create a way to divide a cv signal into 4 parts. Then to have those four parts output a gate signal on seperate outs when in that range. Basically an A150 but instead of two selectable I/O's to have four or some thing like the quad seq. switch but not sequential with the stage selected with a cv range. Thanks, Scott

I'm not sure I understand your goal precisely. My best guess would be to use the A-156 quantizer. Take your CV signal and scale it with an attenuator so that its entire travel covers only 4 semitones. The quantizer will output a gate signal every time the CV wave crosses a boundary. (I'd think something of that kind might be also possible using the A144 morphing controller. The A144 outputs would need to be very harshly clipped. I've never tried it, but it seems within the realm of possibility.) The quantizer method would definitely give you gates, but I'm not sure I understand how you intended to use them. ksoze604 wrote:

You can make a triple CV switch with an A150 and a pair of attenuators, so that the CV range is broken into three segments. The breakpoint for each segment would be selected by setting each of the attenuators so that the A150 switching threshold is reached at that voltage. If you need to divide the cv signal into 4 parts instead of three, you could use two A150s and three attenuators, one attenuator for each CV threshold.

Ohh, right you are. I assume you're feeding the A150 a high DC voltage to obtain the desired output gates. You end up with gates that ratchet high until the CV drops below their respective thresholds, right? Probably easy enough to work around. buechlerjoe wrote:

There's also the limitation that the preset threshold voltage of the A150 is 3.6V, so nothing south of 3.6V would throw the switch without a boost and anything over 3.6V would need attenuation. Getting the effect fine-tuned would be finicky. unknown freak wrote:

Hope you realize that was facetious. You don't really need a boost, just an offset voltage. For comparison logic, I usually bias the A150 so that it switches right at zero volts. (I'm experimenting with MAX, MIN, and ABS functions applied to random LFOs). Joe

The A-129/3 vocoder 5-channel attenuator/offset comes in handy for these kinds of uses.
