The 9MB dream soundfont is nice, yes, but also try the 8MB GS file (I think it's a Hoontech soundfont.). It's an excellent soundfont!

OMG i'm just realising who you are, i'm really sorry if I have been a bit rude with my precedents posts. Thanks for contributing so much for the community. 😀
You could not imagine how many times you saved me from fastidious searches on stason with your huge retro hardware database. 🤣

GS ? What kind of percussions or instruments this soundfont is adding ? (are they the same types as the SC 55 GS ones ?) Seems interesting 😀

Edit : just found it, apparently it propose way more instruments and new sonorities. One more thing to add in my "to do" list 🤣

I didn't notice that you've been rude or something. Everything is fine. Thanks for your warm words 😀

GS means that there are extra sounds, specified back in 1991 by Roland. That doesn't touch the General Midi specification at all and will have no impact on DOS games as GS is basically just an extension to GM. The reason I recommend this soundfont is that it has been recorded by another company (Hoontech), hence the instruments sound different from the much-valued Yamaha and Roland soundfonts. In my opinion it's quite worth trying your favourite games with this soundfont. It's also well balanced and has very decent drumkits.

It's kinda weird because that's mean that i have a defective sc55 for more than one year now 🤣 During all this time I thought that the horrible sound comming out from it when playing gm files in gs mode were not so strange (like it was mismatching intruments) 😵
If I remember correctly, playing gs files in gm and gs with gs does not seems to affect it though 😐

DOS games set the synth to GM mode (or try to.. ) and let it playback the default 128 GM sounds while GS midi files reset the synth to GS mode and take care of the additional 110 sounds GS offers.

SC-55 however is another case because the first generation SC-55 is _NOT_ 100% GM compliant because when a midi file sends a GM reset via sysex the SC-55 interprets it as a GS reset... Anyways also GM midi files sound accurate on the SC-55 because the instruments are mapped in the right order no matter if which mode the synth is. So it is a non issue and I think your SC-55 isn't defective 🤣

if i remember well the issue on the SC55 (one of the first generation with just the GS logo) only happened with duke3d "fat commander" (strong hissing noize, pops and screwed melody), when played with gsplay set to automaticaly reset in GS mode between each song (when gsplay reset in GM the song played perfectly fine). If you say that "GM reset via sysex the SC-55 interprets it as a GS reset" why a purely GM (if i'm not mistaking) song that may reset the sc55 into GS by sysex can only be played well when the unit was reseted before in GM by gsplay (it's supposed do the same thing in the end) ? 😕 Screwed or incomplete sysex message at the begining of the midi file ? or just the sc55 unit that was drunk 🤣

I have several non-GM SC-55s ... there are no problems with them playing GM games.

The ripped DN3D soundtrack is different than the ingame one .
It has many differences and sounds wrong in many songs, that's because of the midi files transcoding , not the module used. Simply put: the conversion to midi files leaves some song information out or wrong. If you play the songs in-game they sound fine.

I always thought that the duke 3d original midi files included in the disc were bug free 😒
Come to think of it, the first time I tried the sc55 was into duke3d and when I moved to this song using shift f5 I almost sh*t myself (that's really a scary noize 🤣) when hearing the noize coming out from the unit 😵
But after a reset it sounded like it should. I will try to put it agan in service and see if it's not hardware related, I can record the sound it makes, just to be sure that's not some components going nuts.
By the way I found an another sc55 first rev for cheap last week and will receive it soon, I will be able to compare them. 😀

Edit : must have remembered wrong, tested it again and it really only appear with gsplay gs reseting between song 😒 Must be due to corrupt MIDI sysex, feel relieved now 😊
