Bug? or incorrect patching?

heres an fxp... ... leTake.fxp

if i put the note controller on poly2 mode, it only plays every second note...on poly3, only every third....

whats the story?

also u will see why i want the adsrs to have an option for "pad mode" becasue i have heaps of adsrs, and true i want to play it in mono mode, but the cutoffs/res adsrs need to fade in every time i trigger a note, and fade out also.... a pad option in the note controller that creates temporary voices to allow the attack and release of all those parameters would be nice :D im never gonna shut up about this u kno :P

:lol: :lol: :lol:

btw if you want to use that patch for karmas preset library go for it....

Hi Matthew !

have looked at the patch. At first sight it does look like a glitch, but actually it makes sense !

The first thing you have to be aware of is that modules before the controller are polyphonic, while modules after are monophonic.
You know this already of course, but it is important to stress, since
using modulation signals from either side of the controller on the other side usually will cause unpredictable results.

In this case you have the polyphonic Modulator2 wired into the monophonic Filter3. Simply disabling Filter3 or cutting the wire will make you patch work the way you wanted.

So to solve it you have to either make a new monophonic ADSR modulator after the controller and wire that into Filter3 or alternatively move Filter3 in front of the controller in the signal chain.

hope this makes sense to you ?!

Interesting read Kasper, didn't realised Karma differentiated between mono and poly modules like that.

Yep, actually it is an advantage. With this scheme you can place all you effects (delay, reverb, etc) after the controllers in the signal chain, to save CPU, since signal is one voice monophonic at that point.
Unless of course you want them per voice :-)

so i wanted 2 voices panned and effected differently - should i use 2 note controllers? or what?

thanks :D

So, should you? Have you figured it out :?: Please let us know :!:

By voices, do you mean oscillators or instances of a note?

i mean i want to have 2 amps with different panning being fed by different osc/filter combinataions....


Osc1 -> SVF1 -> Amp1 (panned leftish)
Osc2 -> SVF1 -> Amp1 (panned leftish)

Osc3 -> SVF2 -> Amp2 (panned rightish)
Osc4 -> SVF2 -> Amp2 (panned rightish)

It's a tough question then.

You could use two note controllers, probably using more CPU by way of a greater amount of polyphonic modules and saving CPU by having any subsequent effects monophonic. Also, if you just want to pan each osc differently, you'll only need to place an amp module before the output in each signal path - saving some CPU by not having many stereo modules.

Another approach would be to use one note controller with the effects/filters you want placed in the signal path between the oscs and the note controller. I think this might save CPU by only having one note controller, but then again you will end up with more polyphonic modules and you'll need a stereo signal path right the way through.

I reckon the first scenario of having one note controller for each OSC would probably be better on CPU and having each signal path separate right until the end will make adjusting levels etc. of each path easier too. Note that the CPU usage stuff is only me guessing based on what Kasper's said though - he's the authority on what works best, so maybe we'll get some input from him.

I just installed the synth modular today and I was having trouble panning an osc. I have an amp in between it and my controller, but still no luck. I searched and found this, but that sounds like what I was trying originally.

for panning to work make sure you set the amp module, and all subsequent modules, to stereo. theres a little icon top-right of each module, a little it....on circle = mono, two = stereo :D

that's right....or you can simply modulate the pan knob on the output module... that is if you dont care about stereo in your effects.
