In one way or another we would like to add sequencing support to MidiPatch. My opinion:
Use an external sequencer (e.g. Rosegarden or qtractor)
Pro: Can be used with MidiPatch as it is. No changes required.
Con: We need to find/code a way to interface with those sequencers.
Use an internal sequencer (e.g http://tse3.sourceforge.net)
Pro: Tight control over the sequencer.
Con: Significantly more work than an external sequencer
Come up with our own solution
Pro: ?
Con: there are mature and very feature-rich solutions out there - no need to reinvent the wheel.
