I tested guitar to MIDI using Rakarrack and for some of my needs it does work very good, resp. it would do, if I could get a lower latency, but I can't get lower than 256 frames/period at 48 KHz, IOW 10.7 ms. This latency is ok to play virtual synth by a keyboard, but it's to much to "use" the "drawbacks" of the pitch to MIDI conversion, without causing a bad musical timing. If the latency would be shorter, it would be possible to control the drawbacks and to use them, while still playing in time. It's less useful to play guitar and to convert after the guitar is recorded, since then we can't control what the converter should do, this only is possible, if we can listen in real-time, while playing, so that we can directly interact with the converter. I got very good results, but with a bad timing, regarding to the latency. If latency wouldn't be an issue, I also would test gxtuner.lv2. Every guitarist interested in guitar to MIDI, who has no issues with his audio Linux, should test at least Rakarrack. I suspect that a latency half of the one I get, IOW <= 5.33 ms, will be good enough for interaction. I've got no chance to get that low with my RME card :(. I already get tons of xruns when using 256 frames/period at 48 KHz, IOW 10.7 ms and there's nothing I can tune on my machine, it's already tuned. Good software! but the old Linux issue, terrible bad hardware support! I don't think using another mobo with my card would improve it, since the driver for my RME card is a PITA and I guess it's not maintained for my card.
