The MultiSound is basically a pre-GM device (Proteus) combined with a GM synth (TB's ?) that when used for GM (see video) is comparable to a SC-55/88 (and all the imitators). Not quite, in terms of MIDI the Multisound Classic really is nothing more than a Proteus 1/XR with a custom GM sysex loaded. …

I don't think you can force Proteus/1 to be GM compatible simply by altering its patch map. It has an ability to renumber its patches, but this doesn't apply to drum sets. And while Proteus/1 has several drum sets, none of them are GM compatible. Windows 3.1 drivers solve this problem by …

My friend says ra-50 has mt-32 mod with keys: 1. Midi button right side 2. Music Style line (up) 7 button 3. Right with +/- buttin from E-20 to MT-32 set up 4. Midi button again. Correct, that does make it almost fully compatible with the MT32, except for the issue with hanging notes/no midi reset. …

Yamaha DB50XG, DB60XG and NEC XR385 also have a MT-32 compatible mode (TG300B mode, enabled via MIDI commands).

Hi Lex-, I dumped the whole chip with an external SPI flasher and used AMIBCP to make the BIOS show all settings that were previously hidden. AMI BIOSes are pretty easy to "unlock" as long as the settings are there and hidden. Your Igel H830 probably has an Insyde BIOS, the same tools sadly don't …
