Good quality sound. Stubborn little fellow with it's own character. They interface is a lot like Micro Q and easy enough once you get the hang of it. Effects are usable, but I prefer my outboard, the pattern seq is a nice touch but I use logic. It still is nice becouse you can use the module as a drummachine when not hooked up to a sequencer. The current OS is 1.03 and still can get a stuck note here and there but only when scrolling through sounds. Flash Rom OS upgradable, and compatible with software version of attack. (It would be a nice touch if they would offer the software for a discount fot rack attack owners as it can be used as an editor for the hardwere module.
Comments About the Sounds:
great sound, very electro. tastefull kits supplied as well as some lesser nice ones. Just create your own anyway, the supplied banks are a good starting point. Sounds also a bit digital (you can hear those bits if you know what I mean. At the same time it can be warm as well as fuzzy. Allways distinctive though it has it's own character. I don't think it replaces 909 808 etc but as I said it stands on it's own.
