This is awesome! Thanks for sharing! Long live the DX7!
I have the app and have a question. In regards to the Midi capabilities, do you do the USB to Camera dongle to the iPad? I haven't had a chance to play with this yet with the exception of hitting the keys on my iPad screen. Love the DX7 and for free this can't be beat!
Hi Ryan, it is possible to use a Lightning USB to MIDI cable with this app. It also has BlueTooth MIDI (the button to the right of the "MIDI" button). However, some Bluetooth MIDI devices introduce latency. So, we would recommend a regular connection. Good luck, and have fun!
Hi beautiful instrument but I have a problem with the sustIanpedal and the volume button when I apply sustainpedal the volume goes up and release the pedal no sound can somebody help me
Hi Adrian! Thanks for the kind words. We have one idea to fix: It sounds like the Sustain Pedal might have accidentally gotten MIDI mapped to the volume knob. You might try to clear the MIDI Learn Knobs. There is a "Clear MIDI Learn Knobs" button in the "MIDI" settings to the upper left of the keyboard. Good luck! - Your friends at AudioKit.
