Hi, I'm kind of battling with the amplification levels with a mf-1868 es1868f card that I grabbed from ebay and hope that someone here has some experience with these boards. I have a Dreamblaster X2 plugged onto the waveblaster connector. In general, it works, but the volume levels are kind of off …

Well, I guess that is a pretty valid argument. I think I will look around for those as well just in case.

Thanks. Same for me. Built a 486 and demoscene stuff without a GUS is just so incredibly annoying. I can also solder smd ic's so pcb only would also be an interesting option for me, but I guess it's not how shock intends to sell it.

Is there already a ballpark price for this once a public run takes place? I'm just curious about that in my decision whether to wait or grab something from ebay. I'm sure interwave +pcb+parts will be quite a bit more than the $30 or mentioned in the first post, right?

4 button pins: What if Dale decides to use the encoder button 🤣 I can see myself already modding an old case.

This is very awesome. I'll have to get one of those as well.

Whoa, I guess I wasn't notified by the forum about new posts for a while. Thanks for those links. I didn't even realize that the roms are decoded already ;-) I'll have to check this out. Pretty amazing stuff. Other than that, I unfortunately don't know much more about the 94i file format. I'd …

I kind of lost track of how you guys came to reversing the .94i file format and how this is related to the SC-55, but, for what it may or may not be worth, isn't that (from the screenshot) the instrument file format of the old Dream SAM9407 chip used in the Terratec EWS64 or the Hoontech Soundtrack …

yaweta, thanks for the pointer, but yes, I'm aware of all this already, the second link is the programmer I'm playing with. Actually, I'm much more interested in the reversing process than the actual result. If I was, I could probably just buy an XV5080 which comes with sample playback. But to be …

Just wanted to check in after some break. Great work! I'm currently messing around with the JV cards. I have a programmer for them and am thus able to dump, alter and load my altered dumps back into a JV device. Those cards seem to have some structural similarities to the SC-55 wave rom. I have …

let's make consistent terminology : in @Cloudschatze spreadsheet, "Original Key" is the root key or each "Split Points (Note Value)" defines a root key for that pcm data which are assigned to the split point? Lingo is different depending on vendor and sometimes when something was created. I think …

Usually, each sample comes along with a root key and a range around that root key for which the sample is mapped to specific notes. The list of samples then make up the complete keyboard mapping. The range can be expressed in different ways, like lower and upper key or really a range around a note ( …

@Lord: thanks for chiming in and giving us this is very useful information. I'll try if we'll maybe have a lucky strike and it is possibly the same descrambling with the other roms as well or some variant of it. On that note, comparing the munt code and the one you have posted, I'm a little …

Sorry, I haven't paid attention on the rom size of the program rom. Just wondering, do you know where in Munt in synth.cpp the bit reordering in the pcm loading code comes from? If that is also some kind of descrambling by shuffling the bits around every 16 bit, I might take a look at how to attack …

Extremely fascinating work mattw. I'll have to read through it one or two more times to digest everything. Have you tried to look at the jd800 program dump from dbwbp (jd800 waveroms), the guy who dumped them managed to extract the companded waveforms from the JD800? The waveform dumps look pretty …
