While it is not SB16-compatible, it is still possible to add 16-bit mixing in DOS for WSS-compatible and ESS AudioDrive sound cards. MPXPLAY, Impulse Tracker and some DOS games actually support this natively. I added the 16Bit mixing more for fun than really to use it. As my real target for Mod …

One thing to note is that Mod Master XT doesn't use DMA, so changing the DMA interval will have no affect on how it sounds. I've done very little testing of it, so I'm not sure what would be causing it to not be perfect – typically programs that use port-based IO only work the best. Mod Master XT …

I tried it on my (486) IBM with a Pentium 83 MHz overdrive. The speeds went from 108 W 109 R to 365 W 375 R (typically). Much appreciated. :) Isa-02.jpg I tried setting the % to 1 and 2 but it just locks up when I try to do anything on the card. I also tried %255 and it corrupted the USB stick and …

Hi FreddyV - really love Mod-Master. I can get Stereo sound on my XT (with a Breakthrough 286 installed) using 22050 on an ESS Audio Drive 1868 16 bit running in the 8 bit slot. This is the reason for my question. Does the player support 16 bit playback via the SB16 and if so, could we have 16 bit …

Hi, Nice 😀 I think you already asked for the enter key. I have low time for the moment, maybe a new version in 5/6 month. I would like to improve again the PC Speaker output 😀 I also succeeded to improve the mixing speed (Core mixing code) With instructions swap and alignment change (3% Faster)

Need a patch to support CGA, No Monochrome text support. Is there a patch available to add CGA support to GLX? I am so excited to have found this thread - can't wait to try Mod Master today! Yes there is a version of GLX with CGA. Mod Master is really ahead of GLX now, no more comparison possible. …

Hi again. MODML is the same software but supporting less file format to use less memory. There is definitely a problem in the way you use mod master or with your SB 2.0 board. If your SB is an SB1.0 or SB1.2, it will not work. You can also use any other SB compatible sound card (Even Plug and play …
