guitar as a midi controller

kilowogster · Post by **kilowogster** » Sat Jan 23, 2010 12:05 am

Anyone know if there's any software out there that can analyze incoming audio signal, in this case from guitar, and convert it to midi notes on the fly, essentially allowing you to use your guitar as a midi controller? I know there's pickups that are designed to do this, but it should be at least theoretically possible to do this on the software side, depending on how good the audio analysis algorithms would be.

mostly just wondering out of curiosity, although it would be pretty rad if i were able to occasionally use a guitar to control some VSTs and ableton instruments live.

Yeah, this has been on my wishlist for a whiles now - I know there are hardware alternatives out there, but (like you say) it seems a software solution should be possible.

My fingers are crossed for some crafty M4L user to put something together....

Nope, that's a midi pickup.
After a purely software solution.

I think it sounds so crazy cause the guy is feeding it japanese vocal samples.....but it seems to work in real time - would be interested to hear the results if he fed it regular old a guitar sample.....

wow, yes that audio to midi transcriber would be amazing! Does this dude have that available for download? can't seem to find it on his blog...

It is neat seeing programs try to convert the harmonics of sound into some kind of rapid-fire midi sequence, but He never once played anything completely dry. I'm curious as to weather it works more like a midi-vocoder type deal (which would explain why the syllabance isn't there) or ..well, i don't know haha. It sounds very cool and exciting as an effect (i'd even want to use something like that, seen it on player-pianos also haha), but musically a bit static and novelty =p

Looking at "similar videos" this particular one seemed more accurate: http://www.youtube.com/watch?v=OTl3C26v ... re=related

Yeah they will. They're still finding a distributor to make the shipping cheaper.

After seeing that link, and researching those midi guitars, I'm quite sold on the idea. I wonder what kind of midi editing is possible?? (triggering the fretboard without having to use the strings????) Considering that you can hit multiple frets on the e-string, you would think it was a possibility through some sysex mojo.

Well, nobody is pushing you. I'm just sharing it. This is only for those whose open. And to me, this is more recording friendly than any other guitar or MIDI-guitar out there yet. ^_^

Today's cost for a MIDI implant are about 549 EUROS (Roland GR-20 + GK3 Pick Up) and you are not 100% sure of the result.
By using this 'gamelike' controller you will spend less than half and be sure it works, or so it seems...
