Thanks for pointing this out, it’s something I hadn’t used before. It’s not quite what I am looking for though, because of how many clicks it takes to set all instrument values. I don’t need this level of fine control since I never use different instruments within any single track, so having to change both the Src and Dest instrument every time is too cumbersome (much like find & replace).
Yes. I’m making an “increase/decrease instrument number” shortcut, similar to how transpose shortcuts work (alt-f2 is + 1 for blocks, shift-f2 is +1 for tracks). A very simple and stupid shortcut, but fitting a fast workflow much better than any buttoned interface.
EDIT:
Here is a tool adding shortcuts for increasing/decreasing instrument number: https://forum.renoise.com/t/new-tool-3-1-instrument-value-shortcuts/46055
