Re: Program to read EMAX disk images almost ready

2005-10-11 by esynthesist

You're right about dedicating samples to keys in the same preset. I 
will do it like you describe.

The sample rates supported by EMAX 2 are:
10000(*), 15625(*), 20000, 22050(**), 27778, 31250, 41667(*), 44100(*)
(**) and 39000 (**) Hz.

(*): 
EMAX 2: Only available for sample rate conversion, but that's OK 
for .WAV files too. 
EMAX 1: Also available as sample frequency.
(**): Not available on EMAX1 (as far as I understand - I don't have 
an EMAX 1 to check this; I thought EMAX1 could also sample at 39 
kHz ?).

These frequencies are stored in the EMAX disk image by using 
a "sample rate identifier" between 0 and 8 (which corresponds to the 
9 possible values shown above).

I certainly appreciate the fact that you want to be a Beta tester. 
Especially for the "writer" program a lot of testing will be 
necessary.

By the way: the program will only support mono and stereo .WAV files, 
no 5.1 or whatever surround stuff.
But I guess this is OK for us :-)

Bye,

I think it would be more awkward to have to copy voices from other 
presets to make up say a multisample instrument than to have all the 
samples in one preset.  Something like a drum program would be the 
most labor intensive copying and key zoning from multiple presets, 
yet setting a multisample from a 'drum' mapping of however many 
samples would be quite quick.

sampling from the computer.  I do have a question tho, the sample 
rate compatibility with the emax, does that include any of the sample 
rates that on can sample on the emax in?  like 10k, 16k, 22k, 28k, 
etc?  I know those numbers are rounded, so we will have to convert 
them to the actual exact sample rate in the audio software correct?
