Annoying poly~ issue

June 15, 2012 | 11:37 am

I have an audio signal (my guitar) routed through a poly~ where it is recorded and stuttered/glitched etc. I have a polyphony of 4 set for now (to layer 4 guitar loops), so inside the poly~ I have 4 stereo pairs of out puts. The signal is routed through the correct out put i.e. the output number corresponding to the target message sent to the poly~ buy using a loadbang triggering a thispoly~ opening the correct outputs on a gate~

So you select target 1, instance one of poly~ patch is loaded, bangs thispoly~ object which opens the gate~ for the first output. BUT…for some reason all the other out puts are still on. I’ve tried setting the target to zero and sending the gate~ a 0 message to make sure they’re all closed, but then after that when I go back to target 1 the gate doesn’t open. I have no idea why because I have used this exact system before and it worked perfectly! Any ideas?

Hard to say without a patch to look at. I’m using the same method without problems.

Not sure what you’re saying here. All voices are already loaded in the poly. Target 1 just tells poly to send messages to voice/instance 1.

Here is the patch, there’s an external which you may not have but it should affect the issue.

I guess loaded isn’t the correct word then, but like I said I used this exact system before and it worked. It’s quite frustrating really.

I’ve played around with it but didn’t find anything unusual. When you load your patch and thus the poly with it’s 4 voices, each voice gets gated to it’s 2 stereo outputs. If you mute voice 1 then the 3 other voices are still sounding through their 3 outputs, as expected.

Not sure if I’m understanding what your problem is.

What my problem is, or what I don’t really understand is that when I press ’1′ on the keyboard, selecting target 1 thus sending information to poly 1 the audio from my guitar is coming out of all 4 stereo pairs. By all rights should it not only be coming out of the first? Also once I have recorded some guitar into the buffer and audio starts looping, then it’s only playing form the first stereo output, which is exactly my desired effect.

I just don’t understand why the direct audio signal from the adc~ would be playing out of all 4 stereo outs, but the recorded audio just the targeted outs. It’s not really a problem as such, it’s just very confusing.

That’s because the audio inlet isn’t affected by the target x message. It always routes to all voices.
