Motion Synth version 1.1 and above supports MIDI over USB (lightning) cable via the MusicIO app.
As an alternative to using the lightning cable, the Motion Synth SHOULD work with most MIDI adaptor cables designed for iPhone / iPod touch / iPad.
The relevant connector types are shown in these images, and two different connection setups are described below.
Always ensure you are getting a cable that includes the right connector type (lightning or 30 pin) for your iPhone or iPod touch.
We have tested the iRig MIDI (version 1) and it works very well with the Motion Synth. It has an Apple 30 pin connector or one end and 5-pin DIN connectors (male, see picture for 5-pin DIN female connectors) on the other.
If using version 1 of the iRig MIDI, iOS devices with a lightning connector will require a lightning adapter for the 30 pin connector.
The second version of this product, the iRig MIDI 2, uses the lightning connector. However, we have not tested this product and its lightning connector cable looks quite short.
Another option for this connection type is the iConnectMIDI1. We have not tested this product, but it looks like a convenient weight and the cables appear to have sufficient length.
If you do purchase the iConnectMIDI1, ensure that it is the version that includes the lightening connector (unless you are using an iPhone 4s).
Other iOS MIDI adaptors (e.g. the iConnectMIDI2plus) may work for this purpose, but we have not tested them yet.
When using a cable during performance you may find it convenient to use a velcro strap or equivalent to lightly strap the cable to your upper forearm (just below the elbow).
The cable would run from the Motion Synth, to your elbow, and then on to the recipient device for the cable.
This setup will greatly reduce any interference the cable might have on your movements.
