If we were to permit the user to select multiple MIDI tracks and record on all of them at once, how should they select which track records which MIDI data?
Some options: -- The existing "channel" property of the instrument (used for playback channel now) is also used to select events to record. No new GUI element is added. A track records all events on a given channel, but from _all_ selected input MIDI devices at once. There is no way to record multiple channels on a single track. The "default" activity for many keyboard users, of always recording from channel 0 (or 1 depending on how you count 'em) regardless of output channel, becomes hard. -- An additional "channel" property for each instrument appears on the instrument parameter box, specifying the recording channel. A track records all events on that channel, but from _all_ selected input MIDI devices at once. There is no way to record multiple channels on a single track. This seems a bit bogus to me, as we're defining an apparently instrument-level property that has nothing to do with a single instrument (because we still record from all devices). However, it does neatly parallel the way we handle audio input selection. -- As previous, but with some advanced means for selecting more than one channel at once. -- The track has an additional "record instrument" property which contains all of the device/channel stuff to identify a single MIDI instrument, and which defines what channel is recorded. A track therefore only records from a single input device. There is no way to record multiple channels or devices on a single track. We currently have no way to present track-level (as opposed to instrument-level) properties, and it would seem odd to relegate this particular selection to yet another parameter box (or elsewhere). -- The track has an additional "record MIDI device" property, and we finally get around to implementing the "MIDI device covering only a subset of MIDI channels" functionality I intended to do years ago. -- Something else. Ideas welcome. Note that I'm not particularly interested in requirements for pure capability (I want to be able to do this, this and this, and I don't care how), and I'm not particularly interested in implementation details at this point. I really want to know how this should best work in the user interface. I should go and review some other applications, because I can't actually remember how this is handled elsewhere.
