I only build your software until now, since I don't had/have time to test it at the moment. But I'll test latest pull from git ASAP. At the moment I only can confirm, that I was able to launch this versions and they showed up in jackd :): [rocketmouse@archlinux ~]$ ls -hanG /usr/src/GuitarSynth/build/ total 344K drwxr-xr-x 2 1000 4.0K Apr 25 19:10 . drwxr-xr-x 4 1000 4.0K Apr 25 10:29 .. -rwxr-xr-x 1 1000 77K Apr 18 14:39 GuitarSynth2.0a683c4 -rwxr-xr-x 1 1000 77K Apr 19 19:24 GuitarSynth2.9ee232d -rwxr-xr-x 1 1000 77K Apr 18 21:06 GuitarSynth2.dcd272d -rwxr-xr-x 1 1000 77K Apr 25 10:32 GuitarSynth2-ge7356fc Did you already release a git version that is able to handle polyphony? My apologies for not testing it. I promise I'll do ASAP. Your project is cool, very interesting. I don't like to pay for a hex pickup that needs to be installed to my vintage guitar and that in addition needs a stand alone synth to convert to MIDI. I would like some kind of converter that is able to e.g. use my Oberheim Matrix-1000, without damaging my guitar. The Matrix-1000 has got a guitar mode! It's one of my best synth, but I try to use it as less as possible, since if ever a Curtis/CEM chip should get broken, there's no chance for me to pay for a spare part. https://en.wikipedia.org/wiki/Doug_Curtis _______________________________________________ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev
