FYI, there's a feature request at GitHub about it. I haven't pushed it to the highest prio though, because mt32emu-qt already supports the dark theme if it is the system theme of the Qt build itself (as can be seen here ). Albeit, I do admit that the app itself should provide theming, so hope I will …

I'd agree that it depends on the intended usage, and if the goal is to add MT-32 emulation to DOSBox, then an integrated solution is a clear winner. OTOH, if a stand-alone application is needed, it's possible to get an AppImage from SourceForge which ought to be highly compatible with lots of …

Hi Spikey, I fully agree that the description of the panpot implementation in the LA board is confusing enough. The thing is, we can configure values in range 0..14 via a SysEx when writing to the patch temp memory. However, the corresponding port of LA32 has only 3 bits, which permits 8 distinct …

Sadly, no. As I said, each file provides an individual table, it appears for rhythm setup. See the source. Plus, the header of each song defines reverb settings, etc.

To be clear, I attached the "fixed" files for consideration only. Indeed, mt32emu-qt can deal with the illegal bytes yet ensure that all SysExes fit into the expected size 😀

IIRC, either the patch maps or the rhythm maps are different, this stuff prepends every song.

For convenience of editing, I've moved all SysEx messages to a separate file. I have also replaced the FF bytes with zeros and split the last longish SysEx. Seems to sound more-or-less OK now.

Oh, right. The SysEx that conveys the patch map is way too long for old-gen units. This needs to be split...

Hmm, well. These songs are seemingly only for new-gen units. They really play odd on old devices even when we ensure delays between SysExes.

OK, I guess it'd be easiest to use a DOS MIDI player from modern DOSBox yet enable the delaysysex thing like in Copy code to clipboard 1 midiconfig=2 delaysysex This will automagically delay all the SysEx messages to be compatible with old-gen devices.

That's odd. I did the same and succeeded. Note, munt is agnostic to the delay between SysEx messages, unlike the old-gen units, so I would expect the need to edit the MIDI stream to make it a product. Indeed, the recording has to be started prior to playing a song: pretty much each of them relies on …

Oh, and good news: I suddenly tried to record MIDI with mt32emu-qt playing a demo song, and it did the job. Weirdly, I thought it wouldn't for some reason, it was quite some time ago 😒 So one can actually do the conversion with mt32emu-qt, just need a new-gen ROM and some time...

Update: mt32emu-qt offers a possibility to play those demo songs nowadays. Apparently, working out the format was very easy, but grabbing songs from ROM is not, in fact. The first thing to note: these songs need special voice and rhythm patches that are unavailable otherwise (presumably those were …

Hmm, not sure why active sense is related at all. It is an optional feature, and any conforming device should only engage this function once it receives the Active Sense message. FYI, mt32emu does not emulate this either, but we provide a callback in the library, so the client application might …

That's also how I understand it. I guess, the editor opens the MIDI port, sends something, then immediately closes the port. By default, each MIDI connection is served by a separate synth in mt32emu-qt. For added flexibility, there is also a pinned synth mode, as I said above. When enabled, one …

One can "pin" a synth in mt32emu-qt, so that it accepts input from all new MIDI connections, which is more like having a single hardware unit connected to a MIDI port. Albeit, I don't think that mt32emu-qt would work great in a DAW setup. If you need a VSTi that emulates MT-32, better to use exactly …

I'd like to clarify the point of using the ROM images in munt, and probably, the goal of munt per se.

Despite of being a reimplementation, we nevertheless load essential data from both the …

I am not entirely sure what you want to achieve, but if you want to avoid overdrive distortion of the output signal, then your best friend is the Master Volume knob. The output gain is applied in the emulation of the analogue path, thus it won't help anyhow if the input signal is already distorted …
