Can this tool go through a selection of notes and sort these over time, from lowest note to highest note or the other way around?
Yes, with some limitations. For example, I hacked into ledger’s ‘Reorder Notes’ tool to restrict drum notes to specific columns.
The trouble with that sorting algorithm (in an xStream context) is that it requires two passes - one to collect data about the notes and another pass to do the actual re-ordering. Sorting by two dimensions (pitch/time) can quickly become complex.
But - sometimes, simple is good too. I could, for example, easily see a model which would pick out specific notes and place them in specific columns.
It would certainly meet my own requirements for the modification I made to Ledgers tool (which was to clean up drum tracks).
I have to completely disable and re-enable xstream, before I can see any external made changes.
Yes, we need a ‘reload’ button for these sort of situations. Good that you worked it out anyway.
I wanna do some note splitting, I the way that for each num_notes on one col, it will be splitted to num_tracks/cols. E.g. having a mono 16th note track, settings 1,2, it should split the notes alternating. I want to do this for multiple vsti instancing, individual note panning.
Ahh, I see 
Couldn’t really figure it out by just looking.
I thought all the Redux stuff will be in Renoise 3.1?
It’s pretty much the headline of that release: all of Redux will certainly belong to Renoise.
But maybe in a different way than you imagined.
