I just discovered another problem with the drum map view... at least I think so... maybe someone can confirm this.....
If I'm playing through a drum map, I can click on one of the named kit pieces in the left pane, and that will select all the events in that row -- just like when you click on a piano key in the regular PRV and select all the notes. But under a drum map, you can't press Del to delete those events, you can only "cut" them using Ctrl-x. You can also lasso them all with the mouse, but that's not always convenient.
It's hard to be certain, but I think that using the mouse to scroll and zoom is also a little different under a drum map than in regular PRV. It seems to be more difficult to get it to do those things... the focus somehow gets lost, and can't be regained without exiting and reentering that view... or something like that.
Oh... I'm also finding that when I'm using a drum map, and I'm in Track View, and I've got inline PRV mode turned OFF so that I'm seeing regular clips, and I use the Fit to Content command, the content will adjust, but if I then turn IPRV ON, the content is completely not visible. If I then use Fit to Content in IPRV, and then switch back to regular clip mode with IPRV OFF, the clips no longer show any content and have to be re-fitted again. Can anyone confirm that?
Also... I find that sometimes, when using a drum map, the clips in track view show the events as right-pointing arrow heads, but sometimes they show them as full rectangles. Is there something I'm missing here? I have been unable to control this or determine what causes it to be one way sometimes and another way other times.
Plus, if I'm not mistaken, soloing works different when using a drum map. If you solo just the MIDI track, or just the synth output track, its "mate" doesn't also get soloed and so you don't hear anything; you have to manually solo both, unlike with a regular MIDI track where soloing either solos both. At least that's how it's working when they are all in a folder; if they're in a folder, and you *solo the folder*, then drum mapped tracks behave the way non-DM tracks do when individually soloed. (I can't conveniently check what happens when the tracks are not in a folder.) I suppose there must be some reason for this related to the the pathing through the map, but it's counter intuitive. It might be working correctly, but it's not working as expected.
The different variations of PRV, including the inline PRV and Drum Maps, are really not too well coordinated. They're all very similar to each other, especially visually, but they're just different enough to require the kind of attention that is better spent making music than of second guessing mouse clicks.
It's the little things....................
