Sample bit depth?

2004-01-13 by erik_magrini@Baxter.com

how do you know that given there is no means to access the samples 
directly, without being gain-staged by
the engine itself?

>>>It's all speculation of course.  I recorded the digital outs of the 
XL-7 using a drum ROM preset, one layer, with all of the synth gain 
parameters set to their nominal levels.  Note trigger velocity was set to 
max, as was the sequencer volume control for that track, and the master 
volume was set to full as well. <<

my guess is the samples are at full scale (or close to it), and that 
-14dbFS you are experiencing is a function
of the scaled back digital headroom.

>>>Not disagreeing with you (since we really don't know), but here's my 
thoughts.  We all know that the output of the XX-7's has to be attenuated 
in order to account for summing of multiple parts, not to mention 
resonance peaks.  By normalizing the samples to -14dBFS, you're only 
losing 2 bits of resolution, which is a far easier trade off than coding 
for attenuation in teh sound engine itself.  Just my guess though.  Maybe 
Aaron knows?  I asked Sean about this specifically a few weeks ago, and he 
forwarded my email on to the Emu sound department.  Haven't heard back yet 
though. <<<
