Downloaded the demo of Serato Sample to see whether it adds to workflow over Ableton's simpler.

Used Mixed In Key to find tracks in the same key (g minor).

Then started loaded tracks into Serato Sample and used the options to auto-find cue points.

Having found 20 or so samples that could play together in a 16 bar loop, i expanded this to 4 minutes using a number of edits.

Whilst the end result is fairly cheesy, it was extremely easy and quick to throw together, so will probably end up buying.

Comments welcome.
