Sonuus G2M Universal Guitar to MIDI Converter

It's easy to use, just plug in and it'll work.

It take the sound quality as the "does it work?" question, since the thing doesn't produce any kind of sound on it's own.
There's the huge disappointment. Im not a reviewer in general but with this product I had to write one, since it doesn't work good at all.
The latency is the major problem. They say its something around 30ms, well, I didn't know what that means, so I bought it. Now I know, 30ms is far to much to be able to play any kind of rhytmic pattern. If you want to use this to trigger some mean old moog bass or anything, forget it! simply doesn't work, youll fall out of beat instantly.

no problems here. didn't use it for long though :-)

didn't use support

even if the box is pretty well built an all, the use of it is very very limited. Im happy if I could prevent anyone from buying this.

The Sonuus G2M is a monophonic guitar to MIDI converter imported from the UK to the US by Peterson Tuners. The G2M is a small (approximately 1 x 2 x 3 inches) plastic box with connectors on the ends for guitar input and through and MIDI output. The face of the box has four LEDs to indicate operational status.

The G2M has a boost switch to adjust its sensitivity for pickups having a very low output level.

One of the LEDs is a clipping indicator. I found the G2M to be insensitive to having the clipping indicator blink frequently. I noticed that I was most likely to hit the clipping indicator when playing near the middle of the guitar's range. I don't know whether this is caused by the guitar or the G2M.

The unit is powered by a 9V battery with no provision for an external power supply. Plugging a cable intro the instrument jack switches on power to the G2M. The specs claim a battery current drain of 10ma; I estimate that an alkaline battery should last at least 50 hours, depending upon the cutoff voltage. One of the LEDs is a low-battery indicator.

The MIDI output can supply phantom power. I don't know whether this power is included in the spec'd 10ma current drain.

The power LED doubles as an indicator for standard guitar tuning. You tune a string until the power LED blinks as slowly as possible. There's no high/low indication, so you have to start low and bring the string up to pitch. While this handy tuner won't replace a modern highly accurate tuner (e.g. a Peterson or Korg) it is sufficient for the intended purpose.

The G2M tracks velocity (i.e. picking intensity) and bends. The unit is preset to work with synthesizers that expect the pitch bend range to cover +/- two semitones.

The G2M converts a single note line played on any electric guitar to a stream of MIDI data that can be used to drive any synthesizer. The nature and quality of the sound is therefore determined by the synthesizer.

The most important thing about a pitch-to-MIDI converter is how well it tracks what you play. There is always some latency, more so on lower notes than on higher notes. Sonuus specs the G2M's latency at 15 to 30 ms. This is the same latency you'd experience due to the speed-of-sound delay when standing 15 to 30 feet from your amp. It is right on the edge of being noticeable for most players. WIth just a bit of practice you'll find yourself anticipating the note to compensate for the delay.

The G2M tracks well. You have to play cleanly and be careful to mute unplayed strings. The wound strings are a bit trickier than the unwound strings. The pitch detector will often track the changing pitch as you lift your finger from the fretboard. I find it necessary to mute with the picking hand.

The manual offers a number of suggestions for how to adjust your guitar for best tracking. I found the G2M to be remarkably insensitive to pickup choice, volume and tone settings. Picking and muting technique, however, has a profound effect on the G2M's tracking ability.

Too early to tell.

I haven't had a need to seek customer support for the G2M. Assuming that support is through Peterson Tuners (the importer) I can say that I have had a successful support incident for another Peterson product.

I play an amalgam of folk, rock, jazz, classical and pop styles. I first started playing in the 1960s and have become serious about music in the past decade.

The G2M is as plug-and-play as a pitch-to-MIDI converter can get. There are no adjustments whatsoever and no unnecessary features. With proper technique, the G2M tracks very well.

The only thing that's a bit puzzling is the fixture provided for attachment of a carrying strap (not included). I can't imagine why anyone would want to carry the G2M on a strap around their wrist or neck.

I had a Roland GR-30 about eight years ago. I had to modify a guitar to install the clunky and finicky divided pickup. Apart from comping Hammond organ parts, I never found much use for the GR-30's polyphony. Most of the GR-30 sounds are for monophonic instruments. The Hammond was the only decent polyphonic sound. The GR30's piano, for some reason, didn't track well; the guitar sounds were pathetic.

The G2M's monophonic converter is perfect for 99% of what I want from a guitar synthesizer. I use it to drive a Roland SH-32 for lead sounds and pads.
