The Vogel CMI App on the iPad will accept MIDI input from a Core MIDI compatible device, connected via the Apple Camera Connection Kit. Note that many USB devices draw too much power for the Camera Connection Kit. A powered USB hub may fix this problem.
MIDI events are also accepted via WiFi from your Mac, and can be used to listen to voices in many pages and to insert notes in Page R. You can use the Audio MIDI Setup utility on your Mac to route MIDI events from a keyboard or a sequencer to your iOS device. Note, however, that latency in a busy WiFi network can make it unusable for real-time performance or recording. The best thing to do is to have a private WiFi network just for your Mac and iOS device(s).
The Vogel CMI App on all devices (iPad, iPhone and iPod Touch) will also accept MIDI input via the Line 6 Midi Mobilizer and the Akai SynthStation 25. For the SynthStation 25, you can use the Program Prev and Next buttons to change the MIDI channel. If the Midi Mobilizer does not have the latest firmware it may not work. You can upgrade your firmware by plugging in your Midi Mobilizer and running the Line 6 Midi Memo Recorder App, which will check your firmware version and upgrade it if necessary.
The on-screen music keyboard can have a MIDI satus panel at the left of the bezel. Whenever a note on event or a pitch wheel event is received, its details will be displayed here. When you adjust the channel in the SynthStation, the channel number will appear here.
With a compatible MIDI device connected, live MIDI note-on and note-off events, plus pitch-wheel messages, will be applied to the voices currently displayed on the screen. The following pages respond to these MIDI events.
The displayed voice will be played with polyphony up to 8. It will respond to any MIDI channel (omni mode).
The displayed instrument can be played in 8-voice monophony. Each instrument voice responds only to its MIDI channel as listed under the "MC" column.
Note that if you have specified the same MIDI channel number for more than one instrument voice, those instrument voices will combine to form a polyphonic set. Just make sure that you choose the same voice for each instrument voice that has the same MIDI channel number, or you will get very odd results.
The displayed instrument voice can be played with polyphony up to 8. It will respond to any MIDI channel (omni mode).
The instrument for the displayed song can be played in 8-voice monophony. Each track and its associated voice responds only to its MIDI channel as listed under the "MC" column.
Note that there are only 8 monophonic audio channels, and each channel can be used both by the MIDI input and by the Page R sequencer. If you play MIDI notes on a channel while Page R is playing, your MIDI notes will be cut off by the next sequencer note in that channel.
The on-screen keyboard and the Akai SynthStation will play the voice of the selected track. Other MIDI inputs will play notes for the track with the matching MIDI channel.
Once a track is selected in Page R, it is the target for inserted notes. Notes can be inserted from the on-screen keyboard (in which case the notes are inserted into the selected track). There are two possible modes, accessed via the MIDI settings page (not yet implemented):
The one difference with the MIDI keyboard is that the note's MIDI 0..127 velocity will be mapped to the closest CMI 1..8 velocity.
In the other pages, MIDI events are ignored.
