Buchla LPG like module

[DragonSF]

I'm looking for a LPG module. Has someone already implemented one yet? Or any idea. how to do that? AFAIK, it just a VCA and VCF controllled by the same env. gen., but I can't get it right. It sound different to my analog module.

Hi DragonSF, Were you able to make any progress on this?

I started looking into emulating an LPG and came across this: http://dafx13.nuim.ie/papers/44.dafx2013_submission_56.pdf

It's a pretty dense paper but might offer some clues.

Hi,
I've been busy creating/finishing real analog LPGs. But now I got some time to have a look. The paper looks promising, but realising the equations will need some deeper studies. Thanks for the link.

Another reference to add here. The Streams module from Mutable Instruments apparently (I don't have one) does LPG emulation. The code is here: https://github.com/pichenettes/eurorack/tree/master/streams
