As you say, the AdLib Gold is the one that has 4 ports at 388h (but I don't think it has them at 220h). Just for some additional context, the Ad Lib Gold used 388 to 38F by default for audio features. If I remember correctly, most of these were passed through the main control chip, so that not …

I have some question about Midi Playback with ARGUS. How am I able to see if the ROM or some Soundfont (GSFULL4M.FFF/DAT) is used for playback? I know that I can select the Midi-Option? In IW.ini I can see that I can set ROM and RAM Soundfont, but how do I know which is used for playback? I tried …

I will agree with the claims that most IDE hard disks should work with this machine, without the need for additional drivers or initialisation/formatting software. This machine could use IDE drives up to about 128 GiB, I think. PCI controller cards (IDE or SATA) were available to get around that …

This idea should be quite feasible. I have suggested a multiple-parallel-port device some time ago, and member Scali here had a few more concrete design suggestions. However, dreamblaster gave no indication that he has any interest in adding that to his product catalogue at the time.

There is one other possibility. You mentioned using flux to re-flow the joints on some parts. Can you post a photo of your flux container, showing the label? One thing that can cause similar symptoms in such cases is conductivity of the flux. If you applied it a little generously, there may be some …

IWSBOS works MEGAEM now loads innstruments from ROM instead of Patches. When you decide to do some more testing, can you try the same MIDI files from a few days ago, configured for MPU-401 via the internal synthesizer? Recordings aren't necessary, just pay attention to missing notes and other …

Looking at keropi's picture of the completed board again, I am reminded of one thing, though it's probably not relevant to most here: the current pre-prototype ROM carrier board for the ARGUS definitely won't fit with that type of SIMM socket in place. So, if there's anyone planning on trying the …

Recordings. Thanks. Just to confirm, that was with the SC-88 connected to your ARGUS prototype, Mega-Em loaded to pass the data over the MIDI port, and Mega-Em treating the InterWave more like a GF1 (using your old MEGAEM.CFG from the Max, because in native InterWave mode, the ROM is required). If …

Yes, the file would be helpful, in that case, configured for GUS synthesizer with no MIDI output. These are intended to be two separate tests. For the curious, using the InterWave, Mega-Em eats notes under certain conditions and plays some other things very badly. That's why I'm trying to isolate …

I don't need the whole installation, just MEGAEM.CFG. I think I've found a source for almost all of the versions of Mega-Em that have InterWave support. EDIT: Is there anyone who owns an external MIDI device who would be willing to try another experiment? The idea is to connect it to the PnP's MIDI/ …

Having tried a few different combinations, I can say that the sound produced via Mega-Em is always lacking in some respects. The 2 MiB, 8-bit set was better in some ways, but had anomalies similar to the triangle in a number of other places (the triangle was broken in that bank as well). I still …

The PnP repair wasn't anything spectacular: new capacitors, a VERY good cleaning, reflow of the F32 at U10 because it looked weird (still does!) and re-flash of the eeprom. After all these the card was revived Is it just the picture, or is the ROM at a slight angle on its footprint? Is there a …

Any input on that? I wouldn't mind adding a header or even a full implementation - but have to admit that I've never worked with SPDIF before, so some guidance might be required. I have hardly ever used a S/PDIF-enabled device, much less designed anything involving one, but I question the …

I just tried extracting the wave data for the triangles straight out of the ROM image. I won't post that here, for obvious reasons, but it sounds like they aren't honouring all of the parameters in the ROM when using Mega-Em. Basically, they are trying to take some short-cuts, and the results aren't …
