USB connection, a pitch bend wheel, a modulation wheel, volume, input for a sustain pedal, the basic.
a real MIDI connection had been significant ..

UTILIZATION

nothing more simple, it's plug n play.

OVERALL OPINION

tried several models, I have chosen for its price and size for my home studio. Octave for quite a small price so perfect. good on the other hand I would not recommend to those who want to play Mozart in midi, it was not a crazy speed, but it is handy to have it below the elbow.
value for money very very honest.
I do not do it again this election becaufe finally too great for use as I have. but other than that nickel.
