I have a Monster MIDI which uses the same Dream chip and ROM, so sounds essentially the same as the Yucatan FX should . I do not find it that close to a Sound Canvas . I prefer my SC-88VL in SC-55 mode to it. I will probably be buying an X2 when they are back in stock and putting the Monster MIDI back in storage .
AFAIK, the GS ROM Roland sued over isn't the exact same the one that came with the Cancun FX.
It follows the GS standard but doesn't sound close because it had to be changed significantly.Any user with a card that has the SAM 9407 (EWS64, Guillemot) can try the 4MB soundfont, that sounds virtually the same as a Sound Canvas. I don't remember the file name exactly now but its no wonder Roland sued.
So they had to license and change significantly which resulted in the Cancun FX.
I think you may be at least partly mistaken . I can't speak for the Cancun FX, as I have never seen a photo with the sticker removed from the ROM. But even one of Dream's datasheets confirms the Roland source sample ROM was being offered as an option alongside the CleanWave ROM .
According to ftp://retronn.de/docs/pc_hardware/wavetables/dream/9703.pdf , the ROM part numbers are as follows .
Validation for following ROMs
•GMS960800 Roland 8Mb
•GMS970800 CleanWave8
•GMS963200 Roland 32Mb
•GMS973202 CleanWave32MbIf you look at the ROM that will be used for the Yucatan FX : Re: New Waveblaster card : Reptile Paradise - Yucatan FX and Re: New Waveblaster card : Reptile Paradise - Yucatan FX you can see it is a GMS963200
If you look at the ROM from the Monster MIDI that I have : Re: Roland SCB-55 in 2020 - fair price and how to find one? you can see it is a GMS963200
According to http://www.os2museum.com/wp/of-g-men-and-farmers/ , the Roland sampled version continued to be offered as an option along with the CleanWave version, as mentioned before .
The SAM9407 compatible GS soundbank may or may not be the same as the one in the GMS963200 ROM . It would be nice to be sure .
Can you provide some references regarding this ?
You might be right about the ROM versions and i might be wrong about what triggered the lawsuit. Also the cards i was talking about have no ROM's in them but RAM which the software loads the soundbank into when the card is initialized.
As i find the Dream GS ROMs significantly different from a real SC-55 i get puzzles why Roland would get upset about devices on markets they did not care about.
However the Dream SAM 9407 with the particular 4MB soundfont sounds incredibly close to a SC-55, in a blind test i wouldn't be able to distinguish them, as i tested a Roland CM-300 vs a Guillemot Maxi Sound Lite with the 4MB soundbank and personally i was astonished. It seems almost like the SC-55 ROM was reverse engineered and that soundfont was built from that. I don't have proof it happened this way, but i never heard a soundbank that sounded as close to a Sound Canvas like this one does. Far, far superior to a Cancun FX. In fact i also own a Terratec Maestro 32/96 whose ROM combinations sounds pretty much the same as a Cancun.
I don't have an easy way to make recordings but i can identify the soundbank and let everyone know which one it is.
EDIT: OK so i took a look and found that GSSBK320.94B and BANK4M.94B are exactly the same file. Ran a binary comparison on them and they match. The clue was that both had the exact same file header.
Now, this soundbank as played by the SAM 9407 to me sounds different from the Cancun, and for the better. It also sounds pretty much the same as my CM300.
