Well... I finally found where that bright sound was going. Seems I had my emulator mixing at 32000hz (the rate the real MT-32 mixes at) and DosBox's mixer set at 22050hz. As such, all the high frequencies I was generating were been downsampled out by the mixer. In the latest binary release then, I've included a dosbox.conf file that makes sure the mixer sampling rate matches the MT-32's sampling rate. I've made a whole bunch of other big changes to this update. Eventually I'll start toying with the reverb settings and whatnot to make that more accurate in its sound compared to the MT-32. As for everything else, I'm still trying to nail down the exact parameters of the lowpass filter (you can hear the effects of this at its worst in the whistle in the SQ3 sample). After that I think I've just about got it. The drums haven't sounded better and a lot of the horned instruments match what I hear on the MT-32. Enjoy. As always, grab it at:
P.S. Snover... how come there's no mention of my emulator on the main MT-32 Emulation page you set up? The last thing mentioned is the decoding of the ROM.
