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.

Before buying this device, you should understand what it does and what it is capable of. It is a monophonic device, which picks up single note guitar lines and converts them to MIDI. Chords don't work.

I'm using it to control a Minimoog Voyager, which is a monophonic analog synth, to play simple, vocal-style leads. For this purpose, the results are pretty good.

This device enables me to play "synth leads" on my guitar, and even "theremin leads" using a slide, and IMO is good enough for home studio use. I would not recommend it for live performance though.

There is a little latency, as each note has to "settle in" to whatever pitch it's ringing at, and then oscillate a few times at pitch before the conversion can be made accurately. The latency is noticable at lower frequencies. This is a physical constant and there's no cure for it.

MIDI does not capture all of the nuances that are in a raw guitar signal. Basically, what it picks up are note on, pitch, and note off. It tracks bends and vibrato as the note is playing. It does not seem to capture velocity.

This device solves a difficult problem pretty well, but you do have to use it on its terms.

As recommended in the manual, you should use the neck pickup and turn down the volume and tone to the optimal levels. Finding the right settings will cut down on misfirings. Unfortunately, this is a bit fiddly and you'll have to find the right settings for each guitar you use.

Works great with slide guitar. When you play slide, you'll be damping the unused strings anyway, and this helps prevent misfiring.

I like to avoid strings 5 & 6 if possible. If I need to play in this range, the synth patch can always be transposed an octave down.

If you hear wrong notes coming out of the synth, you need to think carefully about what is happening. Sometimes it seems like the MIDI converter is misfiring, when in fact device is working correctly, but the synth patch is set up wrong. The pitch wheel must be set to +/- 2 semitones or there will be misfiring, and if you use a slide, you may need to adjust how notes are triggered. (This subject goes well beyond the scope of a product review.)

The only complaint I have is that it doesn't have a 9V jack, which is kind of a strange omission, so I gave it 4 stars.

If you want to play chords don't buy it. But once you practice a little bit with it it's not a bad piece of gear to fire off samples or midi notes when playing notes on the guitar. It's totally monophonic so if your looking for something better certainly buy it rather then this.

Pretty Decent

By hadji457

from Undisclosed

Comments about Sonuus G2M Universal Guitar To MIDI Converter:

I think it's pretty cool. The learning curve is in how you play and in adjusting your synth or sound module.
There really isn't much to this thing, which is good. It's really simple to use. You don't have to be a rocket scientist to use it. You don't even really need to know any thing about midi, either. Just hook it up and go.
There is some getting used to it as well as some tricks and techniques to get it to trigger notes properly. Hot pickups are not good. Use a guitar with lower output pickups or try reducing the volume and roll off the treble. Floating tremeloes will cause mistriggering (if there is such a word) unless you have a very light and precise touch.
Seems to be a solid little gizmo. Only had it a week so, I guess time will tell.
It's a lot cheaper than investing in a midi pickup and interface, especially when I'm just kinda getting my feet wet in this midi guitar thing.

G2M V2

By Kevin Waddell

from canada

Comments about Sonuus G2M Universal Guitar To MIDI Converter:

This is a great unit for what it's intended for. It's not a "guitar synth" and you'll be disapointed if that's what you thought you were getting (as some of the previous reviews indicate)

It's extremely easy to use, virtually no setup is required, and the tracking is suprisingly accurate for a unit of this cost...a little bit high-latency in the lower registers.....as to be expected. I was up and runnining in no time, and had it triggering Xpand 2 in protools easily. Great for guitarists wanting an easier way to write monophonic midi lines on something a little more familiar,

I would recomend this for anyone wanting this ability,,,,but not wanting to spend a pile in the process.

Just don't do it!

By paul-ggldm

from Undisclosed

Comments about Sonuus G2M Universal Guitar To MIDI Converter:

Don't buy this. Maybe I just got a faulty product, but certain notes I play will register as different notes. I made sure my guitar was perfectly in tune but still had the same problem. I tried a different guitar. Same problem. I did notice that it works better on the neck pickup than the bridge, but that really only helped the latency...It will completely glitch on me and play notes above or below the note I played. Not to mention that if you plan on doing ANY type of moderately fast to extremely fast playing, this thing is virtually useless. It will sound like a child trying to play guitar.I give sonuus credit for trying, since guitar midi controllers/converters seem to be still in baby development, and the ones that are decent are way overpriced. But honestly, $99 is A LOT of money for this thing. This is worth about $10. I hate the comments that say "This product isn't great, but for the price, it's worth it!" NO! For $100 this product is certainly NOT worth it. Take it or leave it, this is my advice. I am returning mine.

Must Play Slow

By Steve McArthur

from Jonesboro, AR

Comments about Sonuus G2M Universal Guitar To MIDI Converter:

I hooked the GM2 up to my Yamaha PSR 550 and it wouldn't work. After about 4 hours of messing around with the keyboard program I finally figured it out. The tone coming out of the keyboard is exactly what you hear when you play the keyboard. So, it sounds great. However, I found that the latency problem is dependent on which sound that you select. Strings sound great if you play slow. If you try to play triplets... forget it. The best sounds, as far as having the least amount of latency, were flutes and horns. If you are going to play slow it may work for it.

Cool for the price.

By alividlife

Comments about Sonuus G2M Universal Guitar To MIDI Converter:

I personally don't mind the monophonic because this is perfect for what I need it to do. (Post production on the MIDI roll is fine by me)Some things I wish they would have included?power supply? MIDI tracking threshold/Volume on the device? Ability to turn off pitch bend? Regardless, I use this with Ableton Suite 8 and with the instruments and Native Instruments VSTs this thing is a BLAST. Lotsa smiles and wide eyed looks from people that wouldn't understand the little plastic box.I have no latency issues, but definitely some tracking issues.For example, with drum racks, most of the kicks go to C2, but a guitar tuned to C can be kinda floppy on the string side, so you get some ghost notes. That being said, I would not consider this a live tool. But for quickly recording MIDI tracks, then audio tracks, and back and forth-- this is perfect. Cheap!

DONT BUY THIS PRODUCT

By Alex-2q79L

from New York

Comments about Sonuus G2M Universal Guitar To MIDI Converter:

I thought this would be a great inexpensive alternative to midi pickups. Boy was I wrong. This thing sucks. It's a monophonic converter for a POLYPHONIC INSTRUMENT!! You can only play one note at a time! What's the point?! And it's even bad at that! This thing barely picks up what you play. It has trouble if you go below a C on your Low E string (FORGET tuning to anything lower). Further more, Sonuus knows the product sucks! In the instructions for it, it says "If the G2M is having trouble reading what you're playing, try playing it at half speed and speeding it up in your software", which is to say, our product sucks, fix it with something that doesnt. overall, its a total waste. I returned mine. I'm saving up for a midi pickup for my guitar. You should consider the same, and save yourself the hassle

A Great Solution for the Money

By Jim Goodin

from Brooklyn, NY

Comments about Sonuus G2M Universal Guitar To MIDI Converter:

I bought the G2M as an affordable alternative to interfacing my guitar and some other instruments with midi. Though there are negative marks regarding 'ghost' notes, tracking and some latency when you consider what this device does do for a nominal investment it's for my needs excellent. I actually don't find tracking or latency problematic. With midi guitar or other instruments as I also use an oud on this you have to come at it differently. You really in my opinion have to think of using midi in more of a textural way. If you are desiring it to track your speed playing you need to be sensitive to the type of synth 'patch' you choose as using something dense and thick will not track well. This all said the G2M worked immediately out of the box. It does help to preamp your instrument going into it.

Comments about Sonuus G2M Universal Guitar To MIDI Converter:

This is an interesting little box. It does exactly what it says it does. It will 'read' the audio from your instrument and trigger any midi device with the data it gets out of that signal. The quality of how it does that is entirely in the ears of the beholder.Setup is a snap. Once the connections are made, it instantly starts sending appropriate midi messages. I've used it with Dimension Pro, Rapture and a few other soft synths, all with varying degrees of success.In general, it works well. There are a few ghost tones here and there, but they can be mostly eliminated with clean playing. I've not had the problems others have with poor tracking. I suspect that this is heavily dependent on the quality of the setup. Follow the directions.I've found that turning on 'boost' and lowering the volume on the guitar definitely helps as does using a neck pickup with the tone down. Proper intonation is also important. Notes out of tune even a little bit can confuse the device.The downside is definitely latency. I'm disappointed at the amount of time that passes between hitting a note and hearing a sound. I've tried just about everything to lower this to little avail. I assume this is due to the amount of time it takes for the device to determine the pitch of the note and unless the built in electronics can be sped up, you'll just have to live with it. A trick I've found that really cleans things up is to alter (In your synth) the amount of pitch bend available. If set to zero +- it seems to generate much more pleasant and less warbly sounds. I do like this thing. It's great fun and I really hope Sonuus continues development. I really don't mind the fact that it's monophonic. It would still allow me to play a sax solo or something like that. Right now the latency keeps it from being as useful as it could be. I can hardly wait for the G2M2!
