this is good stuff. i just tried 4 other wave players from this site . none of them worked properly in my setup. i have sonar 5 studio. i don't want to name the other products but if you use sonar do yourself a favor and get this one. other wave players got stuck notes, froze my computer, one shot at me a lot of white noise. i wanted something with adsr controls. and this one has it, with a nice touch; they show attack or release times in seconds, not in abstract numbers. stereo samples play back in stereo(some other vstis didn't). paax even has nice fx, reverb chorus and delay. integration into sonar seems to be excellent- when you save a sonar file paax window pops up asking you if you want to save paax's bank.excellent. you don't have to worry you made edits that you are going to lose. good stuff. it could be a liitle simpler to use. like you have to specify range to import a sound, even if it's just one sample you want spreaded across the whole keyboard. but if you used a sampler or some other vstis before you can figure it out. it's not as easy though as ,say, sfz simple player. well, it's a price to pay for all those functions in music technology. i don't know about documentation or support for it. so , ignore my marks on those two.
