There’s a remarkably thorough comparison of three drum-machine plug-ins here. The guy compares key features of Tattoo, AudioRealism’s ADM, and Sonic Charge’s MicroTonic. As Chris said on his blog, one ends up concluding that one needs all of them, although personally I was never completely taken with MicroTonic’s sound.
Another Tattoo Review
(Like Carl) I really like Microtonic for percussion.
I’ve been holding off on getting Tattoo because I don’t “need” it and IL’s Drumaxx will be a cheap way to keep me busy for a while, but I do like the looks of the mod seq part and the randomize options of Tattoo.
Microtonic is certainly a nice piece of work; I almost bought it but it just doesn’t completely do it for me. But then I have an Elektron MachineDrum which is what I mostly use for drum/percussion programming.
That review reminds me that I should take a listen to ADM; I meant to when it came out but never got ’round to it.
