The one withing I wish the BSP had was a programable step sequencer like a 303 (Press a note it moves a step, press a rest it moves a step etc etc), so you literally program the steps rather than having to stab things in while its playing.
Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
