Main use: 1. Notation ala Final Grade / 2. Use of educational software ala Synthesia
I can attest to that here at last everything goes as it should run.
Before that I had known this "cheap" USB MIDI "Dings" bought for couple of EUR here. Although it has in the notation work (99% - see note E) but with Synthesia then hardly there because the pedal is outputted as an E tone and have other features did not work either.
Here everything works! Shipping was quick I'm Happy.
PS: The interface looks very robust / qualitative impression. Are certainly also better - but it is also more expensive.
