you probably know most producers don't use just one snare sound in a tune and layering samples with the loop capture can get hard if you are loading a lot of samples.

heres what i do:

1.open a new file in ableton

2.make 4-8 audio tracks

3.load a different sample of the same type (or not) into the first scene of each track

4.go the track delay and set each track off +/- 10-15 milliseconds (if you want that natural feel)

5.make sure your sampling setting on the sp-555 is set to auto

6.select your pad and arm the sampling

7.trigger the scene

you now have layered multiple samples in 15 seconds
