Hi again, I saw this and make me doubt... https://www.youtube.com/watch?v=bMBp0wntOSc So, DataLow and DataHigh are not 2 different "registers", we select the register before. These are the ports to send the data to the registers. The only 16 bit OUT sent to the GUS in my code is to send a 16bit …

I'm not sure that code is "valid" -- when you write a 16-bit word to a port, the low byte goes to the port and the high byte goes to the port+1. You are right, as the Address+1 is another register, it will fail. The only way is to build hardware for this.

Just think, you could be world first.... I did think about it and if the new project I am working on is a success, I will be able to support it with 100% accuracy on a "Special" Hardware. :-) I'll test the new version on both 8086@8 as well as 8088@4.77 but I probably won't be able to test until …

When I check GUS Code, I see that there are some 16 bit registers addressed with 16 bit IN/OUT -8Bit IN/OUT Work on a 8 bit ISA Bus, it depends only if the board itself support it. there is 99% of chance it is not the case. We can also upload the samples without using DMA. I was thinking about doing …

For the debug mode, Press F6 while playing the module. What the mixing does: If the mixing is one buffer late : Does nothing 2 Buffers late : increase the minimum volume to play a sample 3 Buffers late : Drop the next channels mixing. (Stop the mixing) 4 Buffers late : Impossible, otherwise the SB …

Hi, I am really glad that you tested MM like this :) Are you able to test it on a slower machine ? Where can I find the module used in 8088 domination ? It can be great to test it on a 8088 :-) (Faster than 8088 Domination ? ;-) ) Regarding the mixing speed, check the improvement I did below. Now MM …

Hi, I was in a retro computing convention this week end. I was the only one with a PC surrounded by Amiga :) This was fun to play 8 channels MOD when an amiga 500 Can't. They were really surprised by this PC playing MOD. I added one more Buffer: The result is nice. I changed the sound card in the …

add [di+0],ax 4 The code is set up so that the offset from di is always in the -128 to 127 range, so this instruction uses the 3 byte encoding. Ok, nice to know :) Thanks for all your infos. I realized that I did not read correctly the cycles count doc. I started to code 2 month ago, after a break …

It would be slower. The original inner loop is 12 bytes but your changes make it 14 bytes. Are you sure ? I count the same size and my code use faster instructions: mov ax,ES:[DI] 3 mov bl,[si+0000] 4 add al,ES:[bx] 3 mov bl,[si+0000] 4 add ah,ES:[bx] 3 stosw 1 18 es: mov bl,[si+0000] 5 mov al,[bx] …

Hi, it is me again. So, finally, to simplify the test, I added the Frequency change with the Left/Right Keys under the Output device menu :) (For MobyGamer) If you want to test the speed limit, use the Debug Mode. The 2 Counters after the "SlowCnt" are incremented each time the Mixing Code is 1/50s …

Hi, I tried to get MODM22XT working on my IBM PC 5160 but couldn't get it to work; playing a module switches to the pattern/row display but nothing sounds. I don't have a PAS (Quite expensive now :) ) so I don't know what is happening. It is probably because the MODM.CFG File has a problem inside, …

Hi Scali, What do you mean by unrolls the resample loop with fixed indice ? I extend the loop so that I can check if we are too far each 64 samples and not all the time. When I listen at Mod Master and GLX playing at the same frequency rate, GLX has like a small pitch difference, It is difficult to …

Hi, I mix into a single buffer, but there are 4 x 1/50 of second buffers. When the Sound blaster is playing the 1st Buffer, Mod Master is mixing the 4th buffer. For example, If we have this during 4 x 1/50 of Second: 1 : 4 Channels 2 : 3 Channels 3 : 2 Channels 4 : 2 Channels -> This is like mixing …

I use 4 buffers of 1/50 of seconds. It is a simple trick used a lot.... This is enaugh to be faster than glx in some cases. Then if it is still too slow, It do not mix the last channels and channels with a small volume during the next buffer. At the end slow volume Channels are in pause during 1/50 …

The current version is not so bad, but support only Covox on 0388h and Sound Blaster in DMA Auto Init mode. Is there a place where I can …
