I bought this pedal device only to simplify the control of my keyboard, organ and computer synth MIDI programming for live gigs! As it was advertised you should be able to "Send all types of MIDI messages via 5-Pin, USB, Bluetooth output". Sounds fantastic, but:
If you are serious in MIDI programming then you will need system exclusive messages (SysEx), for example to change "Send" or "Receive" MIDI channels or to activate a specific "voice" on a MIDI device.
To program the AIRSTEP controller board you will have to use the corresponding AIRSTEP app, on an Android or iOS device. To my total surprise the maximum length to program MIDI SysEx messages in the app is limited to 5 (five!) bytes.
Any SYSex command I needed during the years hat at least 10 bytes, meaning I cannot get SysEx MIDI programming running due to the limits in the app. So the advertised text is just misleading!
I got in direct contact with the supplier XSONIC and they promised that the needed functionality will be available in app version 2.0. Still waiting for it, for months!
Finally, this controller is build like a tank! If the rating was related just to build quality it would deserve 5 stars. It also comes with lots of more features, but unfortunately the one that I was in need for is not working.
I will be happy to update this text as soon as the product is usable in a sense it was advertised for.
