Emax

I just made some comparisons based on your bass drum WAV files.

In a first test I have sent the 0DB and -4DB WAV file via MIDI DUMP to the Emax, using Alchemy on Mac.
--> Result: there is no distortion in the samples on Emax, but imho the result doesn't sound at all like the original WAVs. The samples on the Emax have quite a low volume (no real problem) but also some annoying high pitch in them and they sound dull.

In a second test I have created an Emax bank with EMXP.
--> Result: there is a clear distortion on the 0DB sample, but the -4DB sample sounds very good and is almost identical to the original WAV file (or to the EMAX-II version of this sample).

Of course the distortion of the first sample is not OK, so I will check EMXP's conversion algorithm. It's clearly a problem of  amplitude level because the distortion is caused by clipping. So I'll have to check the normalization level in my algorithm.

Maybe I will include an updated version of this algorithm in the next EMXP v2.07 (aka the "SoundFont2 release") which I hope to launch as a BETA version within the next 2 weeks.
