It kind of works, but it's not the same thing, and we loose an oscillator in the process.
No problem in software.
Just set the number of voices higher, or spawn a 2nd instance and stack.

pulse width modulation is possible with some trickery
-Set both osc's to square , and same tuning
-only osc 2 is enabled in mixer
-enable first sync mode
-set pitch envelope for second osc to 5
-set pitch envelope to invert mode
-PLay with pitch envelope attack/decay stage

Voila ..true pulse width
Not sure I understand why the pitch envelope is necessary for that. The envelope execution in such simple synths is a single iteration.
So, what exactly is happening based on the above instruction?
Second oscillator is synced to first oscillator. When the second oscillator changes tune (controlled by the pitch envelope), instead of tune drifting (will not happen because it is sync'd the first oscillator), that will cause a kind of phase modulation (which will sound similar to PWM because we have square waves here).

At least that's how I understand it. :shrug:

Well , if you have 2 square osc, same pitch , osc2 slaved to ossc 1
Both waveforms have the same duty cycle , both have the same +/- dc component >
If you raise the pitch of the slaved osc. it's duty cycle will beome shorter but the pitch is still determied by osc 1 ,iow :typical sync sound
But if you slightly lower the pitch of osc2 ( slaved one ) it will have a longer duty cycle , the dc component of the slaved square wave is longer , but still being reset buy osc 1
Result is a pulse wave
If the pitch of slaved osc 2 is too low , you will only hear that positive dc component while still being reset by osc 1 , result will be silence .

Free synth. Discontinued. LOL. :D
I get that free synths aren't exactly money-makers for the developers and that they're eventually discontinued. :wink: I just didn't see anything from Martin on this so far this year, so I didn't know if he'd really stopped developing it. Of course, I can understand if he has, and I wouldn't ask him to fix the problem if the synth really is discontinued.

I was also wondering if anyone else had noticed this issue. It's very easy to reproduce: just turn on the portamento in a patch, save the project, close and re-open it, and open the plug-in. It will still show that portamento is on (including wherever you set the time slider), even though it isn't now. And turning it back off and on doesn't solve the problem. Even re-loading the patch doesn't solve the problem. But if you mess with the portamento settings long enough and keep hitting keys, you can get it to alter the tuning even after you release the keys. It may then work for a few keystrokes, but then it's off again.

If the synth is discontinued, that's fine, and I get it. But has anyone else had this problem?

Ive never used portamento on pg8x so cant help you sorry. But I can try and see if I have the same problem. I'll get back to you.

Thanks. I never used it before, either. But after a friend told me about the issue, I tried to see if it would happen on my system. Sure enough, it did. And we were using different DAWs and different versions of Windows.

That's what I thought. Thanks for taking the time to try it.
