Load Multi-Sample Instrument, Load Another, Undo: Too Slow.

Steps to reproduce:

  1. From the Puremagnetik pack, load ‘UprightBass-Plucked.xrns’ in slot 1
  2. Same pack, load ‘Toy-Melodica.xrns’ in the same slot 1
  3. CTRL-Z

This is extremely slow.

This happens more often than I would like. I forget to change slots, so naturally I undo, then I always regret it and die a little inside.

Why so slow?

Its not really slower than loading the old patch again here. Both packs have a shitload of samples so it will take a while to load, but extremely slow is probably something else? How slow is extremely slow in seconds?
