I want to create kick-samples, snare-samples, etc... by layering recorded samples (e.g. 909-Bass-Drum + click + crunch). Also I want to cutoff frequencies to get suitable samples for the mix. I use the EQ-Eight in Ableton to do this, but this is not relevant for my question.
Do I need to layer and merge the raw samples into a single sample first before I cut the frequencies away?
Or do I need to cut off the frequencies of each sample before I merge them into a single sample?
