The Sonuus i2M musicport combines the features of their G2M guitar-to-MIDI converter and B2M bass-to-MIDI converter with an optimized USB interface for even faster performance. Designed particularly for guitar and bass, it works with most musical instruments including wind instruments and the human voice. Now you can record great-sounding synthesizers and samplers the way you always wanted to: by using your favorite instrument—no modifications or MIDI pickup needed.

Featuring extended MIDI features and configurability to satisfy the most demanding users, and a high-impedance audio interface that won’t suck the tone from your instrument; the i2M musicport is the new way to connect your musical instruments to your computer.

Plug and Play
Using class-compliant USB drivers built into your computer’s operating system, and with no special instrument set up required, the i2M musicport offers a true plug-and-play experience for all musicians.

Ultra-Fast Monophonic MIDI Conversion
Although latency is unavoidable when converting musical pitch into MIDI messages, the unique technology used in the i2M musicport™ reduces this to a minimum. Not only is the MIDI conversion extremely fast, but accurate and robust. In fact, the pitch-bend detection of the i2M musicport is more accurate than many popular guitar tuners!

Fine nuances of your playing are captured by the i2M musicport: note velocity is determined from how hard you play; and subtle vibrato and bends are converted to ultra-accurate pitch-bend messages with virtually no latency. Everything from the emotional subtlety of a ‘cello solo to the most extreme use of a guitar’s whammy bar are tracked flawlessly.

The optimized USB MIDI interface further minimizes latency by intelligently managing data packets and avoiding the inherent delays in the traditional MIDI hardware protocol.

Flexible MIDI Architecture
The MIDI converter architecture is very flexible and powerful comprising six zones (splits), each with configurable pitch bend, MIDI channel, transpose and other parameters.

Hi-Z USB Audio Interface
The i2M musicport features a very high-impedance (Hi-Z) audio input circuit. This means it won’t degrade the tone of your musical instruments, unlike typical line inputs—often a problem with electric guitars and dynamic microphones. The input pre-amp also has adjustable gain to accommodate a wide variety of musical instruments.

High quality 16-bit, 44·1 kHz (CD quality), and 48 kHz (DVD quality) digital audio can be recorded into your favorite audio application, or used live, for example through amp-simulators with great-sounding results.

An ASIO driver (only supported on Windows operating systems) is available to provide low latency audio and features the unique ability to use any other audio device (even other ASIO devices) as the output audio device so you can hear everything you do in real time.

Future-Proof (Upgradeable Firmware)
To support new features and to make it future-proof, the firmware (internal software) of the i2M can be upgraded. This means you can invest in the i2M musicport with confidence.

Pocket-Sized/Huge Possibilities
Fashioned as an in-line ¼" jack-to-USB adapter, and about the size of a car key-fob, the i2M musicport has an ultra-compact design that can easily fit into your pocket. But this tiny box will redefine your musical possibilities. An invaluable composition tool, it will let you access new sounds with ease, enable you to create tab and scores, provide you with new inspiration and let you have more fun than you thought possible. Go on: Unlock your music!

Desktop Editor Software
The i2M musicport features a very flexible and powerful MIDI converter architecture with 6 zones enabling MIDI to be sent on up to 6 MIDI channels simultaneously, with each zone being independently configurable. You can customise each of the operating modes for your particular requirements and exchange these settings with other I2M users. Four presets can be stored so you can switch between these without requiring the Desktop Editor Software. This software is available for Microsoft Windows, and OSX (10.5 and above)

Note: The i2M musicport doesn't include its own MIDI sounds, you must use suitable software (sampler, synthesizer, sound module etc) or your computer to record or to hear the MIDI output.

This thing is BETTER than sliced bread!

By Christopher Careaga

from Prescott Valley, AZ

When I first read about this item I was skeptical because, frankly, I thought it was too good to be true. I mean, a device that turns analog signal coming from a guitar into digital MIDI as well as acting as a strict audio interface where I can plug directly into my computer and use Amplitube or Guitar Rig...and for 150 bucks? Too good to be true, right? Wrong. This little gem does everything it claims and does it well. That being said, there IS a learning curve. For a fretboard person to understand how a pipe organ is manipulated takes some practice but it DOES work. On the other hand, playing the guitar into a sax synthesizer will be a no-brainer. All in all I am beyond glad that I bought this. Any guitarist with hopes of creating music in a studio style without paying a lot of money needs one of these.

Amazing tool!

By Renee Slade

from Eugene, OR

Just like the other reviewer... I was skeptical. All the midi guitar stuff I have tried, well, sucked. This allows me to play in REAL TIME! Great for arpegios. My favorite is using it in Reason with a good Cello sampler. Glides, bends, vibratos... it does them all. Amazing....

This little piece of equipment works great!

By Floyd Back

from Mars Hill, North Carolina

I haven't tried it with my guitar yet, but wow, hooked up to Ableton Live 8, using my voice only with effects galore, it was amazing. If you are into doing music in a completely different way, this is really an interesting way to do it. Unlimited potential.
