portaMid: A portable MIDI interface for iOS devices.
Updated: May 18, 2021
The portaMid keyboard is a MIDI keyboard that works over the Bluetooth Low Energy (BLE) protocol which allows one to control music apps on any Apple iOS device. The device contains a 500 mAh lithium polymer rechargeable battery which lasts for many hours of use.
The one octave of piano style keys are soft to the touch but contain tactile feedback so that the user knows when the key has been pressed. Utilizing the octave keys, the user may lower or raise the octave in which the piano-style keys play. The LED represents the octave selection via different color output.
