Hi,
Would it be possible to add an option to activate an instance with an on/off button instead of the A/B drag-up gesture? In a rich arrangement it's very annoying to have to slide the finger all the time to find the instrument you're working on; single-tapping would be much faster IMHO. BTW the gesture doesn't seem to work at all when using the app in a desktop browser (Safari) with a mouse (although resizing does).
Even better, make the "instance activation" customiseable with a CC so that you could assign e.g. CC3 to a pad or button on your (physical) MIDI controller and just tap it to instantly find the instrument you need (without needing to play a note). This CC wouldn't need to be recorded in the arrangement and therefore would allow playback of multiple tracks without VIP getting confused.
On a side note, on my iPad, when I tap a cell in a row other than the first one, the cell on the first row gets selected instead. Only then can I tap (again) the proper cell below in order to select it. In order words, if the top-left cell is (X0, Y0), when tap e.g. (X3, Y3) I get (X3, Y0). Then I need to tap the same cell again to enable it. Whether the cell is enabled or not doesn't make a difference (although if it's disabled, the first tap *does* enable it, just before selecting the first-row cell).
Thanks.
