An easy-to-use, highly effective, guitar-to-MIDI converter.

The G2M Guitar to MIDI Converter from Sonuus is universal because it doesn't need a special pickup mounted on your guitar. Instead, the G2M simply connects to your guitar like any other effects pedal or tuner.

Designed to give accurate triggering, with low-latency, the Sonuus GM2 is a true plug-and-play solution for monophonic MIDI guitar. It can be used to sequence bass lines and guitar solos add an edge to your live performances—it opens up many creative possibilities. No modifications are required to your guitar, there are no special pickups to install, and nothing needs to be "stuck" onto your instrument. It works with all electric guitars.

Robust Performance
Research has shown us that the most important aspect for pitch-to-MIDI conversion is reliable and reproducible triggering of notes. While low-latency is important, robust triggering is the key to usability—you can easily adapt to some latency, but you cannot adapt to random, spurious notes.

By virtue of the unique, inherently robust technology used in the G2M™ you will be able to reliably generate accurate MIDI quickly and easily. Notes are generated exactly as played, and the nuances of your performance are captured with fast, accurate pitch-bend data.

Improves Playing Technique
For optimal MIDI conversion, your guitar playing needs to be clean and accurate. Accidental notes, resonating open strings and other sounds can often be converted into undesired MIDI notes. Often you don't hear these when playing guitar yourself, but can detect them easily when listening live to the generated MIDI. Striving to improve MIDI note accuracy encourages clean picking and accurate fingering, with good control over non-sounding strings by damping them. Not only will your MIDI output be more accurate, your normal guitar playing will sound clearer and more professional. It's like having a tutor sitting beside you giving you advice. It's also great fun!

Usage Ideas

Sequencing bass lines
The G2M™ is great for sequencing natural-sounding bass lines. It is often more convenient to play the bass line using the higher octaves on the guitar where tracking is most accurate and latency is lowest. The resulting recorded performance can then be transposed in your sequencer to use as a bass line. Many sequencers will allow transposition of any number of semitones. Then, for example, you can play on the 3rd string and transpose back to the 6th string or lower.

Enhancing live performances
Mixing your live guitar sound and a synthesizer sound generated via the G2M™ and your sound module or software synth provides a new dimension to your playing. Add to searing lead lines with a detuned synth lead, add rich harmonies using a transposed patch, get a huge wall of sound using bass sounds an octave down to follow your lead playing or rhythm picking. Once your guitar signal is translated into the MIDI domain, there's no limit to the layering of sounds you can achieve.

Guitar Solos
Tricky-to-play fast guitar parts such as solos can be recorded into your sequencer at a slow speed so accuracy can be achieved in the performance. Any mistakes in the recorded MIDI can be edited out in the sequencer and the result can then be played back at the required speed by changing the sequencer tempo. And because it's MIDI you don't get any of the transposition artifacts you would get if you tried to do the same with the original audio!

Notating your music
The G2M™ is a great input device when used togther with music notation software such as GuitarPro and Sibelius and most Digital Audio Workstation (DAW) software such as SONAR, Logic and Cubase. No longer do you have to think about how you will score your guitar part, you can simply connect via your G2M and play.

This thing works just fine!!!!!!!!!!!


from New Jersey

Comments about Sonuus G2M Universal Guitar To MIDI Converter:

This little box is great! So what it's monophonic? I hear all the other complaints about that, but it's not a problem. To achieve polyphonic, simply add the necessary midi notes to create the chords you want on a finished track. If you don't know how to edit midi then you shouldn't be using ANY midi tool or recording midi at all. With that said, this device tracks nicely. If you want to really get a great feel, do what others have suggested, and that is to slow the track down to a manageable level, record your parts, then speed the thing back up. Then just do all your edits and you will have an amazingly realistic feel on any VST instrument since you are playing the notes on your primary instrument - you guitar!!! Get this thing; it's well worth the price and it performs well.

Great Idea, Poor Execution


from Arlington, TX

Comments about Sonuus G2M Universal Guitar To MIDI Converter:

Im not on Sonuus's payroll, so here's the truth about this product. It would have been awesome IF it really worked. It sorta tracks, but is so skiddish that it makes more noise than notes. I watched plenty of Youtube videos before my purchase, it is now obvious there were trained musicians (Sonuus hired guns) using this. IF you are really precise at only playing a single note, no vibrato-steady finger, silence all other strings, move very slowly, then you might get a tone, key words slowly and might. Great novelty toy, but too expensive to be classified as a toy. I can see it being developed in the future and actually becoming the replacement for Rolands' expensive guitar synth can hope!!

good little converter

Comments about Sonuus G2M Universal Guitar To MIDI Converter:

I'm using it in a different way than originally intended, but still getting decent results. I'm using it with my melodica that has a piezo mic built into it and a 1/4" output connected to the G2M. Even at the "boost" setting, however, the output isn't quite strong enough to trigger the accurate pitch, but it's pretty close, considering! I will look into ways of boosting the output more, maybe with a preamp.
