[gmpi] Re: 3.9 (draft) use cases and stuff

Can we close this and move on?

Sorry, Tim, but the following statement is just not correct: 
All sequencer plugins start at 0 and have data (or gaps between
data, which really is data) for some length, right?  Wav players have a
single hunk of PCM data or maybe they have multiple hunks spaced outwith
some alignment. But eventually they end.

I assert that if I have a plug-in, and it plays a stored MIDI sequence, which loops, so that the duration is infinite, then I can still call it a sequencer plug-in. For that case, your assertion fails at or near 'All'. Loops are not a pathological case, they're a common case.

Forget about the GUI position widget already.

 but this is by definition impossible: if there are N different
 possible lengths, there clearly can be no single answer to the
 question of what "halfway" means. there's no magic here, and its
 nothing to do with GMPI - you're describing a possibility that does
 not exist.


Not at all.  All sequencer plugins start at 0 and have data (or gaps between
data, which really is data) for some length, right?  Wav players have a
single hunk of PCM data or maybe they have multiple hunks spaced outwith
some alignment.  But eventually they end.

If you convert the total sequence time of each sequencer to a common format
(samples works well :) and line them all up at the left (since they all
start at zero) then your project absolutely DOES have a known length.  It's
the sequence length of the longest sequencer plugin.

 as i said above, if there are multiple lengths, there clearly can be
 no single such controller. by definition, not because we are not

There can be - if we provide some way to know how long a sequence is.

Or we can simplify the whole mess by saying this use case is not supported.

Or we can simplify it even more by not supporting sequencer plugins, and
assuming that the host is the sequencer.  This is maybe not such an
unreasonable position.
