It's a simple drum synth, it makes drum sounds out of noise without using a single fx chain. The macros should be somewhat self-explanatory, though the modulation wheel controls the speed of the pitch/filter bend which is very useful. The pressure switch is a stereo/chopping effect.
(Remember to save the mod wheel to a key command in the pattern editor or as an automation or else it will reset when you try to render the track)
Tip: Swap out the noise sounds with different samples and get your very own personal sounds and effects. ;)
