Guitar to MIDI?

[VampiricYouth]

Is there any software out there in which I can plug my guitar in through my Line-In and play, and each note hit will be transcribed into a MIDI note? I would then be able to save a riff in MIDI and import it into something like Fruity Loop's sequencer and assign it to a Synth?

It's very possible, but it's not as easy(read: inexpensive) as you'd like it to be

Guitar Synth http://www.lateralsol.com/features.html

I tried the demo out, and it's not bad (Probably the best thing you'll get short of buying a MIDI pick-up and converters). There are obvious limitations to the system, as to how you can play to get good results (As is the case for a hardware set-up too, but more so without dedicated hardware). It sells for $39.

Freebies:
Super Eel http://www.kvraudio.com/get/1538.html
Synodeia 2 http://www.kvraudio.com/get/1606.html
(Super Eel is the more flexible of the 2, and has it's own synth engine, and can control other synths).

To get the most of software systems, try this:
Record your guitar as normal. Now duplicate the track (If you plan to mix the synth with the original guitar track, or you could just work with the original file, but I don't recommend it unless you use non-destructive editing). Just before every note change, highlight a small portion of audio (usually just a few milliseconds will do, trial and error for best results), and delete the audio leaving just a bit of silence before each new note.

This will help the software better recognize the new pitch as it changes, as it will allow the software buffer to be free of stray overtones and harmonics caused by such things as fret buzz, open strings resonating, or simply moving fingers over the strings which hit random harmonics that we don't nessacarily hear, but the software attempts to read.

that sounds like a good trick. i'll have to try that one out.

I tried the Laterasol GSYNTH demo. Seems to work OK.
1) my PC wasn't suppose to be fast enough at 350 mhz, but it was fine
2) I was able to connect out to my Roland synth and play it in real time

because It is a demo version, you get blocked every 5 seconds for a few seconds. With demo, you can't save to MIDI, which might be why you might want the software. Big grey area.

My overall thoughts are :
1) I found real time playing was possible.
2) Some GM patches don't translate well from a guitar input
3) terminology ??? does a guitar player know what LFO is ?
The parameter names could be described better, but maybe I'm ranting

Another trick I've learned (especially for frettless instruments, vocals or slurred guitar parts), is to make a copy of the track (processed as above optionally) and run it through Autotune (I don't believe in Autotune as a crutch for sloppy playing, but it is still a valuable tool). Using real aggresive settings will remove most of the ghost notes that confuse Audio-to-MIDI software. Use the Autotuned signal to feed the input of the Audio-to-MIDI, and blend in the original guitar track and...Voila, more predictable (especially if graphically edited) results.

You need to add a GK2 pickup to your guitar and buy a GK2 synth to convert your signal to midi. It is pretty accurate, but expensive. We are talking about 500 to 1000 dollar here. Good Luck.

The new GK3 is supposed to be much faster (and now supports archtops).

Hope this helps!
