The Sonuus G2M Converter is, at $99 almost cheap enough for me to impulse-buy. But I’ve played around with guitar-to-midi converters from time to time and I’ve always been disappointed, and besides, after paying bills I’m already broke for July.
This thing is, of course, monophonic, and who knows what it does if you play a chord. That is usually pretty comical, and not musically useful with this sort of device. What I liked is the way the sales copy seeks to turn the drawbacks with audio to MIDI conversion into a virtue:
“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!
In other words this thing is no better than any other attempt to extract note & pitch information from audio, and you’ll have to practice to build enough technique for it to be even marginally useful…
