Free MIDI over Bluetooth App for iPad, iPhone and Mac
MIDI connections between iOS devices have been a continual problem; hardware MIDI adapters are expensive and bulky, while MIDI over WiFi introduces too much latency. Apollo MIDI over Bluetooth provides low latency MIDI connections between two iOS devices, or an iOS device and a Mac. With Apollo, MIDI can be sent over Bluetooth LE wireless connections, eliminating hardware adapters, and providing much lower latency than is possible with WiFi. Apollo uses Bluetooth LE: this is supported by the iPad 3 and newer, the iPad Mini, the iPhone 4s and newer, and recent Mac desktop and laptop computers.
Install the app on two iOS devices, select an "A" endpoint for one, and a "B" endpoint for the other. Press the search button on both, and a Bluetooth connection will be established. After connecting, MIDI messages sent to Apollo running on one device will be forwarded to the other -- and these messages can then be redirected to synthesizer or sequencer apps.
In addition to MIDI connections between iOS devices, Apollo can also be used to connect to Mac desktop and laptop computers. Recent iMacs and MacBooks support Bluetooth LE; for older Macs, a USB Bluetooth adapter may be required. The OSX version of Apollo is free, and is available in the Mac app store.
This version is free, with connections limited to 5 minutes; this should be plenty of time to evaluate the speed, and determine if the app works on your equipment. If you like it, you can upgrade to the full version, which has no limit on connection times. Read device compatibility details.
