Emax

Hi!

Thanks for your input! I gave up on the 12 bit render thing as you mentioned there's no tool that converts to 12 bits. 

On the other hand I experimented with some dithering types and I actually managed to reach the quality of factory samples in terms of noise and aliasing (using the L1). So far I couldn't get that quality from the emax ADC inputs!

The Waves L1 plugin does 12 bit quantize with dither and noise shaping but it's useless, since I can only bounce the results in either 8 or 16 bits. The problem with this is that the 8 bit renders are way too lo-fi and the 16 bit ones will automatically reduce with no dithering in EMXP when I transfer them to EM1 floppys on my PC and the no-dither artifacts are audible again. This is very audible in percussive samples. Simply recording them through the Emax input won't help either..

Or if it's 12 bit, how can I render my samples to 12 bit and not let EMXP mess up my 16 bit samples? I've tried some of the Sound Designer installs available here, but couldn't get them to work on either the mac classic emulator for windows, or emulators for OSX. It seems like I must have been a programmer to be able to get them running so I gave up. Does anyone know of alternatives?
