Are you guys using ak.sys 2.5.3 or 2.6.1? I'm using Mac OS9 mostly but tried downloading 2.6.1 in OSX and it doesnt work - it just shows me info about Ak.sys and doesn't acknowledge my MPC. The 2.5.3 is ok but you can't audition samples before you drag it in (which you can with the latest version). The MpcPgmMaker1.22 is really good, plus it can convert SDII & AIFF to WAV and when U click on the pads it plays the sample. 2 major things tho - it hasn't got zones and the MPC4k can't understand the program it creates since it's really for 2kXL & 3k.
