Is it possible to create autopanning from full left to full right? I have an MSEG or LFO modulating the pan in the output mixer (under the "patchbay"). If I set this to 100% and the source is panned center, it goes from center to full right. If I start full left, it pans from left to center. If I start 1/2 way, it pans half left to half right. How do I pan from all the way left to all the way right? Thank you.

Hmmm, this works just fine over here when the modulation amount is 100%. Try it with the square LFO - it alternates left-right just as it should.

I just made an init patch, white noise generator. Voice 1 is panned hard left, LFO1 is controlling pan with a square wave. LFO Amp is 100% and mod is 100%. Here's the result. Seems like I need "200%" modulation depth.

ere2learn, that link just takes me back to this thread. I understand that the modulator is unipolar, that's why I'm starting with panning to the left and modulating it right. But it's not pushing hard enough.

Fixed it

Yeah, that's what I'm doing. Pan is full left and modulation is full right.

I prefer to do it with an MSEG for better control. Also the tempo sync seems to work better for longer duty cycles.

BTW I am doing this in ZebraHZ, if that makes any difference.

Can't think what's going wrong there, synthetic88. I get complete i.e. 100% L-R separation in Z2 or ZHZ, oscillator / noise / mixer or whatever. Double and treble-check the track's panning and audio routing?

I see (and can confirm) that problem now, synthetic88

.
After realizing that I was using the modulation matrix instead of pan modulation directly in the mixer... duh!

But it does work with a square LFO in the pan modulation in the mixer... I got perfect separation as well.

As Chapelle said, the problem is that you pan Voice1 to the left. The LFO is bipolar, i.e. it goes from -50% to +50%; so in order to get full range the modulated parameter needs to be at center. I've just tested it: pan at 0, modulated at 100% by a square lfo, results in full left/right separation.

Sure, but synthetic88 preferred to use an MSEG i.e. a unipolar source (which doesn't work as expected there). Here's a workaround that uses a modulation mixer to convert the MSEG signal to bipolar:

In that mod mixer, Select MSEG1 and MMap4 for inputs 1 and 2, and set Constant to 50.00.
Switch MMap4 to "Map Quantise" with only 2 values. Set them both to minimum i.e. -100.00.

Could have mapped the MSEG with a 127-value ramp instead, and ditched the mod mixer - but I find the above more esthetically pleasing as it creates a simple, constant offset
