Why not go for an Emagic Unitor8 / Unitor8 MkII / AMT8. They are sold under 100 € mostly. They cannot only merge but route 8:8 with SysEx support. Downside is that routing must be controlled via software.

Not sure how I missed this for so long, I've a rack mount plan in my head for when I get a long term home. but this is at another level. I was thinking of just a rack with shelves to put the PC's kind of like my currant setup. https://i.postimg.cc/Pxd0dnLw/Rack.jpg Nice setup! I don't have enough …

I just wanted to note my project is not dead. But since I've become dad, time has become a very rare resource. The whole signal routing has received a major update allowing me to do some more cool things (IMHO), notably audio mixing from various sources, 2.0/4.0/5.1/7.1 analog HDMI audio embedding …

Before I dig much deeper, I'm curious if anyone else can shed any light on this. Any suggestions for SysEx commands to test out? I don't know what exactly you want to achieve with the SysEx command, but I know there's a SysEx file on The Quest Studio Archives which sends a reset command to the …

Hi there, I'm an owner of both a CM64 and an MT-32 - but to be honest, I mainly use these units for testing. For actual gameplay, I'm very happy with mt32-pi and munt. So even if you're not having access to the real thing™, please don't feel sad. It would be wise to use mt32-pi, but I can't stand …

What do you mean by "every" game? There are plenty of games on Japanese systems that support the CM-64 (CM-32P)... I mean every game which claims to support the MT-32 (whatever the result is). Can we count the CM-32P (and the corresponding part of the CM-64) to the MT-32 compatible devices? From …

The only reason I could see to have all three is if you wanted to play a game without the additional CM-series sound effects, but still required an MT-32 (new) for proper sounding playback. Oh, that's an interesting what if scenario I did not think about first! This would actually be a nice-to-have …

I am planning to use those devices: MT-32 (old) MT-32 (new) CM-32L I watched the ultimate MT-32 tutorial by Phil's Computer Lab. In the end he recommends just the MT-32 (old) and the CM-32L. Is this the whole …

There's a nice project on Github which does exactly what the OP wants, plus some additional stuff: https://github.com/dekuNukem/USB4VC It's based on the MCP 4451. I also had the idea to build something based on this chip family, but I haven't got time for it yet.
