A very good buy in my opinion as it brings a dirtiness that is not found in any other apps (or in 95% of hardware drum machines either).
Plus that it is not sample based but synthesized which opens up a lot of more fun hands on tweaking.
It is easy to get into and have a lot of posssibilites for tweaky fun but it is not for everyone,
but anyone looking for a drum groovebox app to play dirty with should check this out!
Update:
Added amplitude controls to snare and bass drum
Added tone distance control to snare
Added noise control to bass drum
Added presets Dinon, crushed hornet, 806, 807, grid grime
Made font size relative to screen
Changed wav naming convention

P.s-
This video shows it at its dirtiest and want to mention that it is possibe to get a bit more cleaner tones and also the kick can get very punchy which is not so obvious here.
