[Ardour-Dev] let's talk about MIDI regions

[Eddy StEsprit]

One idea would be that every "empty" midi track gets a default, undeletable background region that is infinite in length (or at least, spans the whole session, time-wise,and resizes itself when the start/end markers are moved).


That would:

1) make midi editing less disturbing for new users (no need to create a region first)

2) keep all the good aspects of region editing (linked regions, etc...) as new regions could still be overlaid over the "background" region


Recording while on "edit" mode could rewrite the content of the active region, and create a new region outside edit mode. Or, the MIDI tracks could have (like audio ones) their record mode set to Normal/Tape/Non layered. Or simply (but disruptively) create a switch in the track header "destroy/overlay". Or create a secondary rec-arm that is a "rec destructively".


It may solve the cons you mentionned, but not the illegal overlapping notes... But we keep the consistency between audio and midi AND full compatibility with previous Ardour versions.


Regards,

Headwar

Making this even more destructive strikes me as backwards. Now it's not
only regions that are edited destructively but whole tracks.

It would really be nice if midi editing would be non-destructive.  One
possible way: write a new .mid for every change-set (or on every
session-save).

and
   - quantization

select 2 linked regions. one starting at 1|0|0, one at 3|2|123. quantize
to grid.  It's ambiguous what should happen and it gets worse if there's
a tempo/meter change in between.
