More fun than all those boring Roland emulators. Limited in scope compared to plug-ins like Fxpansion Tremor, but sounds great so who cares? I'm hoping to be able to add my own samples though in the future. In Heartbeat, samples are mixed with the drum synths.
Unfortunately the well sounding on-board effects only work on the master and are only available internally. I use the separate outputs most of the time. Great to have these when not.
