I only use a samplers my to trigger sound FX. For example... I sequenced the song in Jesus Christ Superstar with the 39 lashes. I didn't have a whip sound. So I sampled the pullback of the whip and assigned it to 5 notes.... In order to get different pitches. Then I sampled the crack of the whip the same way. Then I recorded the whip into the sequence.

Oh, I also ueed a baby cry in "Into The Woods."

Otherwise, I never use it. Plus, it can be done more efficiently in a computer DAW nowadays!!
