Re: Windows 10 stops detecting Munt.

Posted on Today, 07:59

I haven't had any issue with Munt since June, and version 2.4.0 so far survived two reboots B) The only glitch was when Win10 rev2009 was released in November. I ran "drvsetup.exe repair" to register the driver again. I realise this is as intended. Still, drvsetup doesn't deploy a driver package …

Re: Munt/Munt Vsti MT-32 Old

Yes, that's right. The mt32emu engine does rely on the data of the control ROM, including when it makes a decision whether to emulate those quirks of the old MT-32 control ROM code. Note, more data is loaded from the control ROM directly, so we don't make a user-settable option to trigger emulation …

Hello matti157, Unfortunately, there is no simple way to make MT-32 emulation work with DOS games in a raw console session of Win9x. As you can find earlier in this forum, merely installing mt32emu_qt and mt32emu_win32drv is not enough to get MT-32 music output from a DOS game, one also needs to …

Re: Munt using D-110 ROMs

Thanks for all the positive response. This is actually something I made because from what I knew, D-110 have very similar synth structure as an MT-32, so I gave it a try. Turns out it works quite well, and it sounds beautiful as well. Although to make it the most complete, I still don't know how to …

From a quick look, the tune starts with a 16-byte title, then goes 16 bytes of system area (?) and the 256-byte patch dump, and then a stream of timestamped MIDI messages likewise from a SMF track go afterwards.

Re: Emulating MT-32 on an RPi2

The routing looks correct to me, so it's weird that there is no MIDI input. I could speculate that the hardware MIDI port can serve just 1 connection though. But given that you have already updated mt32emu-qt to the version with JACK support, I'd try JACK audio and JACK MIDI routing instead. JACK …

appiah4 I gather that qjackctl works well for the task too ;) fsmith2003 If qjackctl could do it for other synths, I see no reason for it not to work with mt32emu-qt. It should also work with mt32emu_alsadrv. Both these programs create MIDI endpoints for the ALSA sequencer, and qjackctl should show …

Re: Decoding Roland PCM ROMs

Posted on 2020-10-14, 05:45

The difference between the decoded data from Roland and the self-decoded ROMs is so tiny that it makes me think it's just the decoding code that's not quite there. Maybe it's a rounding difference or something. Yeah, that's what I mean. Try to figure statistical data from the differences, like mean …

Of course, feel free to start a new thread for it. But I don't insist because I'm not a moderator, yet this thread turned to a mess long time ago :) I'd just note that LA32 doesn't perform the conversion of the PCM ROM data to linear wave like you probably expect . Instead, it handles samples in the …

No, this is not about external ROM chips. LA32 itself contains internal LUTs. More details can be found in https://github.com/munt/munt/blob/master/mt32 … /src/Tables.cpp as opposed to the external ROM set that comprises of the control ROM, PCM ROM and the reverb ROM.

If you're going to achieve bit-accurate decoding with la32_sampleparse.c, you should first of all get rid of powf and the other float math, which is quite obviously not present in the bare metal. As we've found, LA32 contains just two LUTs, one of them permits calculation of the binary exponent. …
