Found some un-encrypted at NDS M10D ROM.
Thought samples seems legit (32Khz, 16bit,LE, mono), Name Block similar to AI2 , but the address block
Meditating on this... ~_~

AI2 pcmcard format decoded
It's been a long time without a post.
Want some news?
I stopped on hardware digging a while, and dug into software side.
With great help of Alex's pcm dumps, Korg's AI2 pcm cards format decoded for.. let's say 98%!
Still my plans to dump all the PCM chips of X3 synth, write a FAQ on pcmcards dumping/writing, and some more.
And now, enjoy some Demos of XSC cards, I found no one shared on youtube yet.
(I'll upload a couple more soon, browse my channel for more.)

I dumped a ROM! (and I like it)
Currently, dumped KORG X2 ROM.
Luckily, "The V55PI instruction set is upward compatible with the V20/V30 (native mode) and V25/V35 instruction sets"
And V20/30 is just 80186 clone, so "It's easy to find suitable disasm", I thought.
Bogus! ( I was hoping for IDA has 80186 support, but...
But I found old good dosbox-running app, called Sourcer. Checking it out now.
P.S. Feel free to contact me, if you need Korg X2 fw file. i'll dump X3 fw soon, and some morre ;)

I always been interesting in all that KORG's chip abbreviations.
No doubt, I have a gut feeling on that TGL is a Tone Generator related chip, but what MAP is?
Unfortunately, I've never seen inner Korg's documentation, like naming convention, or data structures of AI2 synths. (I beg you to contact with me, if you have some ^__^ )
But today, I've got Wavestation service manual, and there were a little, but priceless passage on this:
MAP16 - Decoder/card buffer, The main functions are Gate Array function connected with CPU such as Address Latch, Address Decoder, R/W Pulse Occurrence Circuit and the interface with IC card.
KSP - Key scan processor. Scans the data of the keys, the panel switches, the wheel, the joystick and the pedals, converts those data to serial and transmits them to CPU.
Sweet little passage. I wish there were a memory map and programming manual for TG. ^__^

I am on comparing PCM parts of KORG'z AI synths.
Kinda funny, it seems clear why it is rumoured than one sounds better than another.. I found out, that some chips data lines are tied partly. (8 instead of 16) On X3, two chips used 16bit data bus, and one 8 bit. Is it made for storing compressed samples maybe? Someday, I dump these chips to check it out.
