Load your loops into Dr. Octo Rex - Reason’s loop player. Each player loads eight REX loops and lets you switch between them on the fly. Set the player to retrigger the loops on your call. Or export the slice trigger notes to the sequencer, with the original timing and feel intact so you can create fills and variations from your loops. When you want to get creative with the loops, Dr. Octo Rex has a comprehensive sound sculpting section too, with filters, envelopes and modulation settings to help you craft the sound you are looking for.
