at this point, for troubleshooting, used rom, rom version and which binaries were used, is needed. Which is unfortunate but an inherent problem from all the difrent releases that exist. Even the same for real hardware. Nuked-SC55 from master branch, SC-55 mk1 v1.21 rom. The problematic tracks are: …

However, with the SC-55 mk1 roms, some songs (maybe two) of Duke Nukem 3D don't sound right and the emulator returns the error "MIDI Buff. Full!". Try with the attached midi. No problems with the SC-55 mk2. Wouldn't it be possible to implement some sort of Falcosoft MIDI Player style "CTF filter" …

Thanks @Karmek and @AppleSauce. With mk1 roms v1.21, all instrument assignment issues are gone. Sandwarriors definitely does. And this is with me spacing out the "Voice Reservation" values to be "evenly distributed" amongst the 16 parts for the 28 possible voices. This game looks like it came out in …

Last time there wasn't a complete set of SC-55 roms anywhere on earth, now you tell me that if I search, I'll find them? I ask to avoid wasting time looking for something that doesn't exist 😅. With the mk2 roms, I can use Falcosoft MIDI Player as a "filter" to pass the correct instruments to the …

I noticed that some of the System Shock midi tracks have issues with Nuked SC-55: SC-55mk2. For example with the THM4.XMI track (Level 5 - Flight Deck), the emulator plays "Standard" drum instead of "Power"and Nuked SC-55 returns the error "No DRUM SET" in both GM and GS modes. Using Falcosoft MIDI …

Why did early versions of SC-55 have "capital tone fallback" and later ones like the mk2 not? Maybe because early versions of the SC-55 didn't have a working GM mode, while the later revisions did and so that feature was useless?

- I incorporated Falcosoft's INT16/FLOAT32 code and played around with it. It might not be as clear cut as always using pageSize/pageNum:8192/2 for FLOAT32 - at least not on macOS and linux. Too high a pageSize will cause microscopic tempo stutters, for now something around 6144/3 seems to work …

Yes, and compiling with Visual Studio is not as straightforward as it should be. So more frequent builds would be better. https://github.com/nukeykt/Nuked-SC55/pull/44#issuecomment-2070281797 There is a problem compiling Nuked-SC55 with Visual Studio 2022. Now I don't remember the error …

I've been playing around with optimizing the emulator code for the last few days, and I'm happy to report that I'm now able to run it at ~85-90% cpu utilization (while playing music) on a single core of a stock Raspberry Pi 4! 🎉 I'll do a bit of cleaning up of the code and then I'll make PR on the …

I dont really consider the SC55 unique. Well, if for most of the games the music was composed with SC-55, I would say that it is somewhat unique. what? the mind boggles. i didnt realise what trash the xv5080 was in comparison, and damn the integra 7 is just door stop, who ever compose on that now …

I think peoples response is muted because really... its general midi, its not like MT32 / Munt thats special. sc55 is just general midi, and one with a tiny compressed rom sound set at that. It's not the sound quality that makes the SC-55 unique, but the fact that every midi music from every single …

The midi music of Blood (1997) is broken with Roland midi hardware, in fact with Nuked SC-55 it doesn't work correctly, unless you do a GM reset instead of a GS reset. There is an old fix to apply to the game (https://www.vogons.org/viewtopic.php?f=7&t=36501&p=359683&hilit=blood+midi#p359683) and …

Hi, your VST midi driver works very well but I noticed a problem with Sound Canvas VA. Unfortunately this VSTi takes about 4 seconds to start (probably due to its invasive DRM). It seems like your driver starts the VSTi every time an application requests it and then closes it. Unfortunately, the …
