Mate, this is an extremely simple problem.
If you're using the VDMSound Launchpad, under the "Compatibility" tab, set EMS to 16384kB.

If you're not using the Launchpad, uh, Get it. Now. Seriously.

I use a dos program under XP with VDMS and it works like a charm. The only problem I encounter is when the program is not run with VDMS it has 16 megs of EMS to use for its purposes. When run with VDMS I can only get a maximum of 3.9megs of EMS.

It is crucial that I am able to use the full 16 megs as the program deals entirely with sound sequencing.

What should I do?

Impulse Tracker, right? 😀

Yeah, if you use LaunchPad simply "Run with VDMS" then simply go to the IT's VDMSound shortcut's Advanced properties and increase EMS. If using "plain" "Run with VDMS" (no LaunchPad installed) then simply go to the VDMSound directory, right-click on the VDMSRun.pif "Shortcut to MS-DOS program" file and go to Memory then boost EMS.

You should be able to provide even more than 16MB of EMS (go up to 32 IIRC).

Hello,
I made a forum serch on (Impulse tracker ems) but I still have NO EMS on my new computer when in Impulse tracker..

Do you know other computer where it's impossible to get EMS?

Is there something I can do?

thanks if someone knows how to help me! 😀

Yes. It's becoming more common on the more recent motherboards. It's quite possible that your motherboard can't create EMS.

Create a file named GO.BAT and edit it to contain the single command MEM /C, then run it with VDMSound (right-click and choose Run with VDMS), it should report something like the following:

Cut and paste your results from your command prompt, here.

Also, try running MSD to see if you have a total UMB of 64k or more. This has been discussed frequently. 1st (IIRC) was here. Most recent discussed it here.

Thanks for your help!
Here is the result I have (translated from french):

I am going to read the topics you indicated me.. perhaps I will contact the persons if they had the same problems..
Do you think it is a solvable problem?

Right now, you have no EMS memory. Open up a command prompt and type in MEM /c (no VDMSound here) to find your largest upper memory block.
It should look like:
Largest available upper memory block : 95744 ( 93.5K)
If it comes back with less than 64k, you have problems. Like I said, MSD will give you more detailed info. About your only option is to look into your BIOS, and disable any motherboard hardware that may be eating up your memory space. Preferably, it should be hardware that your aren't actively using.
