Thanks, it sems to be working perfectly (tested regular .NET 6.0 x86 version). I like the feature that during import the dialog shows the first MT-32 LCD message contained in the Midi file. BTW, this editor works perfectly with my Munt VSTi plugin. Timbres found in a Midi file can be tested easily …

Updated version v0.9.7a is now available- please see the link in my original post. The application can now read MT-32 SysEx data from .mid files, although I only have a small number of these to test with. I've also added an autosave feature, and the ability to load a file at startup (either from the …

Looks like a crystal oscillator in a ceramic package- the markings suggest a 4MHz frequency. Should be easy enough to replace if it's gone bad. Edit- technically it's called a ceramic resonator (https://en.wikipedia.org/wiki/Ceramic_resonator), but its function is similar to a crystal oscillator.

I'm not a .NET expert but I have heard about NAudio when .NET core not even existed. So I would be surprised if some older versions of NAudio had no support for .NET framework at all. According to its nuget page even the current version still supports .NET Framework 4.7.2 and 4.8 https://www.nuget. …

What is the difficulty compiling on NET 4 or older ? Apart from the need to remove any .NET 6 and C# 10-specific features from the code base, the MIDI interface currently relies on the NAudio.midi library, which isn't compatible with .NET Framework 4.0. I don't plan on making any major changes to …

I've now published an updated version 0.9.6a- see the link in my original post.

These are only the SysEx messages and the game itself does not load …

However, it appears that no cache latency settings are stable at this speed. Setting latency to 6, 7 or 8 (default seems to be 5) allows the Windows desktop to load but crashes shortly after starting 3DMark 2000. Setting latency to 9 or above appears to disable L2 cache entirely, with CPU-Z …

That's a shame. L2 cache definitely seems to be the limiting factor. My CPUs will run happily at 450MHz (4.5 x 100) with L2 disabled in BIOS, although they don't get past the POST screen at any 500MHz configuration (5 x 100, 4.5 x 112 or 4 x 124). You could try out the tool "WCPUL2CacheLatency". …

Yes, it will do 333Mhz at 66 x 5. I did get it to post at 366 (66 x 5.5) and 400 (66 x 6) as well, but haven't done any detailed testing of those configurations.

I acquired a 350MHz Deschutes PII (SL2S6, 1998 week 43, Ireland) a few days ago and was very surprised to find that it has an unlocked multiplier. It's not a particularly remarkable overclocker- it runs stable at 400MHz (4 x 100), but crashes at 450MHz (4.5 x 100) shortly after loading the Windows …

This appears to be normal behaviour- the original MT-32 was designed to be connected to the line input on an amplifier, mixer or tape recorder. When directly connected to a passive device such as a set of headphones, the maximum output volume will be very dependent on the impedance of the connected …

I don't own any motherboards with an integrated ESS chip, but I expect DOS would see it as just another Plug & Play ISA sound device. Any data being sent to the MIDI Out port (usually 330H) would also go to the appropriate pin on the wavetable connector.

Game performance with a 1GHz Ezra is comparable to a 500MHz P3 Katmai. I've not (yet) managed to …

Does it get detected by the BIOS? I've had plenty of dusty old ISA cards which only came to life after cleaning the contacts on the edge connector with some contact cleaner then pulling them in and out of the slot a few times.
