Im on a dual processor G5 mac, I have the miniMgV and it works great,BUT I also bought Analog factory & installed the"RELOADED" update and this product just is NOT working right. I have found numerous problems with it so far, Heres a quick description: 1- Most of/if not ALL of the sounds are distorted(even at low volume) 2-pops & clicks happening while playing sounds, 3-Stuck keys & STUCK NOTES on the virtual keyboard, 4- Twice so far, I've found the EXACT SAME SOUND on 2 different presets by 2 completely different authors! (for Example: preset 1 by john doe will be the EXACT same sound as preset 2 by joe whatever, I've found this twice so far, but I just can't work with the program the way it is now,so IM not using it
