Re: [xl7] Here comes the science... (Well, some questions...)

- The manual says that MultiSets store initial preset selections for   the 
32 MIDI channels. I wasn't sure why (given that patterns select their own 
presets) - but of course a pattern has only 16 tracks. What seems to 
happen is that, when a pattern is made active, it initialises the presets 
for the channels addressed by its 16  tracks, leaving the remainder of the 
32 preset slots alone. Does this sound right? (I'm not going to think 
about what happens if multiple tracks address the same channel.)

>>>Not totally sure I understand you, so forgive me if I don't answer what 
you're asking.  Basically, when a new pattern begins to play, the first 
thing (well, almost) it does is to send a program change message on all 32 
channels loading up the correct presets you saved with the Pattern.  Even 
though a pattern only has 16 tracks, you can have multiple MIDI channels 
on each track, thus the 32 channels total. <<<

- A change of track channel assignment doesn't dirty the pattern -  why? 
And yet, the new assignments appear to be stored with the pattern anyway 
(I'll double-check this.) Similarly, a new selection of preset in a track 
doesn't dirty the pattern (although this makes more pragmatic sense).

>>>What do you mean by dirty? <<<

- How would I save a preset when the pattern is dirty and I don't want to 
save that? (Assuming the preset is on a track, rather than a trackless 
channel.) I can't revert the pattern because it'll revert the track's 
preset selection, losing the preset edit. I can't scroll to a trackless 
channel and leave the preset there, because the edit buffer is lost. (All 
the world is not a Waldorf Micro-Wave, alas.) I guess all I can do is 
store the pattern somewhere temporary, save the preset, and blow away the 
pattern later.

>>>Presets are saved seperately from Patterns, so if you've got a preset 
you like save it in a User Preset location.  All the Pattern remembers is 
the program change #'s assigned to each track. <<<

- Where is the initial setting of the GLIDE button (on/off) stored?   I've 
been assuming that it's part of the track initialisation, but it's 
remembered (temporarily at least) for non-track channels.

>>>It's based on the Preset settings, not Pattern settings. <<<
