Originally posted by LIONSTRACS: well..for the boards that I can see there..
On the Main PCB they still use always the NEC embedded micro controller, so forget about have the 1-2Gb DIMM ram promised and of course the USB 2.0. For this features need one X86 CPU.
The Audio PCB board is nice developed and include the SAM9708, 128 Voice with max 256Mb ROM/FLASH and can streaming up to MAX 2 stereo voice. here the datasheet: http://atmel.com/dyn/resources/prod_documents/doc1772.pdf
Solder this all 11 Flash for me is crazy, when give avaialble Flash chip of 64 and 128Mb too. For me was better develope a dimm slot, where is possible učpdate mode easy, like the flash on MS: http://www.lionstracs.com/store/images/9b74722e9a28b8e18eda606b1ae24e6e_large.jpg
Then they have included the two SAM3308B: http://atmel.com/dyn/resources/prod_documents/doc6090.pdf
are the new dream chipset for decoding 1 Mp3 file, for that they need 2 chipset for fade 2 audio players.
Sam3308B, can stream 1 Mp3, max 32 voice and max 64Mb RAM/Flash
I THINK one SAM3308B is used for the keyboard, for that also you can load max 64Mb (-the OS firmware code and tools) mean that remain the 47-48Mb available.
The second SAM3308B is used for the MIC effects, vocalist and so on..
In fact, if you read the Audya specifications: http://www.ketron.it/prodotti/dettagli.asp?sezione=1&idProdotto=30
the ROM size seem match and also the 197 voice ( here we have to discuss, because when the al effects are ON, you lost about 60% of the voice)
So..for what in this moment I have understand the audya work in this way:
arranger: the style will be played on SAM9708 because is the big one that can store the all 256Mb ROM data sounds and also streaming from HD up to 2 stereo WAV files.
In this way they can store the all audio DRUMS loops from HD and the all parts from the ROM side. Note that each Wav file can not be more as 4Mb size ( Dream specification)
Midiplayers: they wil be played on SAM9708 too, in fact you can fade-mix two midifiles too and they need of course the ROM sounds.
Keyboard: here I'm not totally sure..maybe they routing the midi OUT of the keyboard to the SAM9708 too, for play the all basic ROM sounds. When wil be used the keyboard sampler, they will switch the midi OUT to one SAM3308B, for that you have available only this 48Mb sampler.
In fact if you read the atmel specification, you can NOT share the same memory/ROM to others chipset, every chipset must have the owner static working RAM and Flash/Rom.
For me seem only one Midjay more expanded, always with the same hardware, nothing new.
The BIG problem of this all manufactures is the ROM Sampler system.
Untill they will not jump to the X-86 system and use a true sampler software, they remain always limited on this range.
IF they will jump on X-86 remain the problem: wich HD streaming sampler to use?? 
All the software sampler under windows, forget it, because then mean to install the windows OS, license and the all issue that we know...
Remain the Linux...Linuxsampler without interface, all TCP remote controlled, BUT they wil NOT buy me the license too.
the end....IF they choose one PC ampler, they have to porting all again the 20 years of sounds ROM story to the HD and then you can copy all...
For sure they will be never interested to jump to X-86...
look here: http://www.asrock.com/mb/overview.asp?Model=A330GC&s=
with one X-86 mainboard like this ( cost around 80 euro) they can resolve this all issue, COST 200 time MUCH less than develope a propietary CPU mainboard.
This is used now on our new keyboards, stage pianos and Vasio synth.
Anyway is better to see what ketron can make with the new software, BUT for now, with this hardware do NOT dream to have more hardware features...( I mean about RAM,HD Sata, USB and so on..)Clear message here, go buy LIONSTRACS if you want all singing,dacing, bells and whistles, or "shut up a your face". Wonder if LIONSTRACS does Autopsies, what's the dirrence in cost between Audya and LIONSTRACS.
