Korg iMS-20 Controlled By Guitar + Audio To MIDI Adapter

This is a demo of the Sonuus i2M Musicport – a USB audio interface that converts audio into MIDI signals.

This example shows how to control Korg iMS-20 on an iPad using a standard guitar. The Sonuus i2M Musicport converts guitars and other musical instruments to MIDI with very low latency. Being a standard USB MIDI device, it can work with the iPad using the iPad camera connection kit.

While the Sonuus i2M Musicport was designed with guitar and bass in mind, it works with most musical instruments, including wind instruments and the human voice.


  • 16-bit, 44·1 kHz/48 kHz digital audio with Hi-Z input preamp.

  1. This awesome! Price is a little steep, but prob won’t stop me from getting it. This will help solve Logic’s problem of not outputting MIDI via AU.

  2. Price is very reasonable if it works like the video shows. Consider the alternatives… Z-tars are thousands of dollars. YRG’s are seriously flawed. Hex pickups are problematic and hardware mods are necessary. And SentientFX has failed us all.

    WIll definitely pick one up. Can’t wait!

  3. The original bass version did NOT work at all. I spent a long time trying to get it to trigger accurately with appropriate technique, strings, touch, etc. I hope this one works better.

  4. I bought one to use with guitar. It was extremely inconsistent, so much so that it got returned for a refund. There’s no way you could use one on stage.
