Re: [RELEASE] Nuked-SC55, low-level Roland SC-55 series emulator announcement

Yes, this would be opt-in for Pi 4+ - I will have to do some tests across the various models :) I'm glad you told me this - I will remove the calls to render(float*, ...) now that I'm aware Munt is internally integer by default, because it is causing an unnecessary conversion: int -> float -> back …

Well, crap - that's me humbled. 😔 Thank you for the clarification; for years I believed that it was only necessary to call the float flavour of render() (I'm using the C++ API). You're absolutely right; we get RendererType_BIT16S by default in the constructor for the Synth class. 🤦‍♂️ I think I need …

In 16-bit integer mode (which is the default and is also used by mt32-pi)... FWIW, this is false - mt32-pi uses the floating-point render path for both Munt and FluidSynth. mt32-pi is compiled with aggressive NEON and vectorisation optimisations enabled and so even the Z2W can comfortably use this …

If you want to reset the synths without a full reboot of the Raspberry Pi, you can just use a standard MT-32 reset or a GM/GS reset SysEx message, but only when in the respective synth modes. MT-32: F0 41 10 16 12 7F 01 F7 GM: F0 7E 7F 09 01 F7 GS: F0 41 10 42 12 40 00 7F 00 41 F7 mt32-pi-control …

mp32l.JPG Thanks for sending me this, @dreamblaster! After testing it over the weekend I've found that it performs just as well as the other mt32-pi HAT solutions I have tried (and there are many), as expected. For those who haven't yet noticed, mt32-pi v0.10.2 is available , and in this version …

I've now tested all of the mentioned games on a PII 400 machine with a Vibra 16 and joystick port to MIDI cable, and my usual Pi 3B/Arananet PI-MIDI development setup. All games sounded fine. Only TIE Fighter triggers an unexpected status consistently on startup for me; Duke3D only did it once or …

Doom and Duke are well-tested with mt32-pi. I've tested these games with it so frequently over the past year that I am sick to death of hearing them :) Hence, this is making me suspicious of PC/sound card hardware, and there's not much that can be done if testers are going to be shy about giving …

Only got the dreaded "Unexp MIDI status" on the screen when starting a game. Which game? Does it happen once or several times during the music? So far, zero people experiencing this have given specific examples of games for me to investigate, and the reports are too vague, therefore nothing can be …

Yes, it should be possible to do that quite easily. Munt has a useful reverse stereo function which I can simply expose in SysEx/config option. On my list for the next release.

MT-32 mode seems to have left and right channels reversed but fluidsynth mode does not. It is easy to test with Wing Commander. This is correct, there is no bug here (except maybe in Wing Commander). The 'drops' come out of the left channel on my real MT-32. As for FluidSynth/MT-32 panning being …

I'm curious though: it seems to be designed for use without a fan or heatsink. Won't that possibly cause thermal issues with the cm4? The Pi 4 SoC (and by extension the CM4) is known to run hot when at maximum clock speeds and CPU load; a heatsink is a good idea for any Raspberry Pi and they are …

amazing work again d0pefish!!!! Thankyou for the kind words! mt32-pi stands on the shoulders of giants, however - Munt and FluidSynth have been available for a long time now and the people behind those projects deserve utmost respect. All I've done is tried to build a dedicated "appliance-like" …
