sonuus i2M musicport

It's exelent, now I can record melodies with my voice in MIDI and choose the sound I want.
by Sweetwater Customer on

Impressive, not perfect

Great concept, and apparently very tough to get solid MIDI notes from an analog guitar. But thanks to firmware there’s room for improvement. Nevertheless, even with some of the overtones, especially with bass guitar, the Sonuus creates a sound of its own. Using Reason, MIDI bass sounds unique, a cross between bass strings and keyboard bass, but closer to bass strings, at least to my ears. In fact, some of the anomalies (even after deleting stray MIDI notes), sound really neat, including the transients that Sonuus suggest be avoided. In comparison, I think keyboard bass is too clean, and I’ve spent years using a keyboard as an input device because there wasn’t much choice.

Sonuus opens up a whole new community and the i2M is stellar because it works with guitar and bass, unlike its predeccessors which had two either/or products. Sonuus says the i2M is “future proof” via firmware, and I hope that’s correct instead of being superceded by another device involving expenditure.

Being able to edit MIDI, change tempo, and select different voicings is a big plus over editing audio, which is pretty much WYH(hear)IWYG. Overall, I think Sonuus, analog, and keyboards all have their places in music, at least in my project studio. I’ll use

It works, it's fun, it's (mostly) easy

I've had it for a few days now, and have used it with an iPad/Garageband, and a Macbook Air/Logic X. It works as advertised, but you need to keep in mind that it requires a little practice and experimentation to get good results. Do everything that the manual says, and in addition I recommend using a good conpressor. My setup is a 4 string electric bass w/passive electronics, fed to a Seymour Duncan studio bass compression pedal (purchased here). Using the compressor lets me fine tune I'm an intermediate bass player and an advanced piano player, but anyone with a basic understanding of guitar playing can use this effectively. I give four stars for 2 reasons:
1) there is noticeable latency (this is not a defect, but a consequence of the physics of sound propagation + digital processing limits) that would hinder the I2M in a live performance. If you are playing slow mellow strings from your bass, no problem. If you want to "play" piano, then you better get a keyboard.
2) I don't give 5 star reviews.

Awesome little gadget

Awesome gadget, I've been jamming with it and reason 5 synths all morning. Tracking is really good, not perfect, but definitely the best of its kind, also for the price it's a great investment for any guitar player. Tracking will be perfect if you can cut off all guitar nuances, because sometimes it will read picking and fret noises as notes, but all I had to do was run the guitar through an eq prior to the i2m and then it was perfect. I'm using a pod x3 live prior to it, all I did was set a shelving eq cutting everything from 2.5khz and up (like a low pass filter but less drastic) and that's it. Keep in mind the tracking was very good before the process, so it only got better. Piece of advice, when using with synths be sure to set the pitchbend of the instrument you're controlling to 2, 3 semi-tones tops, depending on your bending strenght and usage.

You probably won't notice its size, but it's about a lipstick big, will fit in any pocket and it's also USB powered, so no battery replacements to keep in mind or anything.

A great tool.

The i2m is very easy to use, and sonuus provides good software to support it such as the musicport editor and the asio driver which allows you to chain another interface as your output.

I was intending to use the i2m with a bass but I have found that a guitar is better suited due to string physics which dictate latency.

The i2m is most handy for me when writing midi parts in a sequencer as I am more acquainted with guitars and basses than keyboards.

I have found that when using a guitar with the i2m to control a synth it can easily be used as a live instrument; however with a bass the response can be glitchy and delayed so be aware.

I must also commend Sweetwater for having the fastest shipping online.
