Many hardware keyboards lacks a decent pitch wheel. Weeel saves the day!

Weeel is a MIDI utility app that transmits pitch bend and any control change (like modulation, breath control etc) to any MIDI port available on the device.

Use it with hardware MIDI interfaces, Network MIDI or other solutions like MusicIO or midimux (via Virtual MIDI).

• Touch and drag to transmit pitch (x-axis) and modulation (y-axis)
• Acceleration sensitivity setting
• Lock/Unlock modulation (whether it should go back to zero or not)
• Transmit pitch bend on/off switch
• Select which MIDI ports to transmit to (on/off switch for each port)
• Select MIDI out channel
• Select control change number (0-127)

Please note: This app does not alter or create any sound at all. It only transmits MIDI data. If you’re not exactly sure what it is for: do not buy it.

Awesome Company

This is a great, yet simple MIDI utility that does what it says. I had a question and the Dev responded lightning fast and they were very helpful. Thank you! I highly recommend.

not great

only allows you to change the cc message transmuted by the Y axis. X axis is always pitch bend... i wouldn’t have bought it if i knew that and i’ll change this review if the developer addresses this issue.

Didn’t work

This app did not send MIDI pitch bend and modulation out to my Casio piano over lightning-to-USB-B. The Casio shows up in the app settings but the piano does not get the signal.
