How do you interpret the voice data from the firmware? Maybe I don't need to desolder my ROM after all...
The total size of that bin file is 32768 bytes (0x8000)
I checked the file with a hexeditor.

The voicedata start at address 0x4da0

Each voice uses 67 bytes ( = the first 67 bytes of the 128 bytes VMEM voice parameter bulkdump format, up to the 10 bytes that contain the voicename....
THANK YOU!

Yes, I meant to shout, 'cause I'm an idiot. My Hex editor showed me a length of 43 between starts of voice names. Now that I wanted to check what you described, I finally saw the length was in hex. Okay, yes, 67 bytes do make sense - all it needs, no Pitch EG available. 43 just didn't make any sense, so I suspected it to be neither VMEM nor VCED...

Cheers, Florian
