Version 0.3 Changelog
New engine! FormantPerc is a drop-in replacement for PolyPerc based on a new UGen, FormantTriPTR, which is a formant oscillator inspired by Mangrove. The script will automatically install the new UGen the first time it is run after the update; using the UGen will require a SYSTEM > RESTART (for a total of two restarts; sorry)
Experiment with FormantPerc’s params in the Params menu!

This looks amazing! Unfortunately I can’t get any sounds out. All levels are up. Am I doing something stupid?

after the first run, Lamination now requires a restart of SuperCollider to make sound—this is an unfortunate side-effect of how it installs UGens. does the problem persist after you do a SYSTEM > RESTART?
Another thing to check is the outs params? it should be set to Audio by default but maybe somehow you’ve changed it?

Ok, a restart got it running. That’s embarrassing but thanks and having great fun with it now.

glad you got it running

lamination is a LOT of fun and sounds fab - thank you!!! I am just getting started here. I have a question about the formant oscillator: with some minor changes in the params, it gets very “squelchy” occasionally. Is that a part of how the FormantPerc engine works as you dial in or is it something else? Here’s an example of the “squelch” (resonance?) where it starts with squelch sound and I begin adjusting the slope to move away from the squelch sound. Thanks for any insight you can provide!

I believe the squelch is a “feature” of the design—if you’ve played with Mangrove you’ll know that at certain settings the oscillator will exhibit somewhat chaotic behavior as it struggles to decide which division of the incoming frequency to oscillate at. I believe the same thing is what’s happening when you hear the squelching here. As you noticed, moving Slope or Formant will avoid them.

Ah - got it - thanks! I’ve not played with Mangrove so this is new to me. Thanks so much for the insights here =)

Hi! I highly recommend updating the script. I significantly improved how Lamination manages FormantTriPTR, which will allow future scripts using this UGen to more easily coexist with Lamination.

I’m missing the bin directory from where FormantTriPTR is copied from after installing. Or something.
Looking forward to trying out the new version =) I’ve just updated lamination via maiden and it’s hanging out on the loading... message. Here’s the supercollider output in maiden:

hmm. will you try giving your norns a System > Restart and then loading Lamination again? I thought I avoided this weird semi-working failure state, but I may not have

The new update removes the bin directory in favor of an ignore directory. Are things not working?

I copied the engine manually over SSH from ignore into the ~/.local subdirectory, now everything is working fine. I think i might have had the target directory, but empty, so if-condition on line 72 was not reached and files not copied on lines 73 and 74.
@mmryspace 's error above looks like the one I had.

This didn’t resolve the loading... message
Here’s what things look like at the moment:
Hope this helps troubleshoot!
oh I see, this is my mistake; I had solved this chicken-egg problem and then not pushed the result. there are two solutions possible: one is to copy FormantTriPTR.sc from /ignore to the Extensions/FormantTriPTR folder manually, and the other is to update the script in Maiden and try again
1 Like
Ok, all set! Thank you! For some reason, the update from Maiden produced a jack fail message after restart from the Norns. I had to hard reset with the button on the bottom of the Norns. When I copied FormantTriPTR.sc from /ignore to the Extensions/FormantTriPTR folder manually, that did the trick.
1 Like
hmm, the jack fail is probably unrelated: I occasionally get that when I do SYSTEM > RESTART, particularly when I have a lot of peripherals plugged in. Glad to hear things are working
