First off, this ain't no review, this is an electronic biopsy.
Ok. so I picked up this little bugger for about $100 because it seemed like a neato drum machine.
Curiously, knowing Akai and their lazy however effective design ideals of "Lets grab a bunch of off the shelf chips that do at least one of the things we want it to do and build some good gear around it" I decided to pop this bugger open.
I didn't expect much, after all it was 8 pads, 4 buttons and a Rotary knob.
However, the chips inside gave me a bit of a bit of surprise.
The main chip is a Medeli A2 Processor chippy which looks like this:
Possible Datasheet, seems to be at least close: http://www.icmedeli.com/download/M2000SPEC.pdf
The other notable chips are what appears to be a 1mb flash chip for the A2 Processor to boot off of Marked 1.0.0 which oddly in the Factory reset mode the "SD" is listed at 1.0.0 even after I installed the factory update, Note the Midi Error is because I had nothing plugged in at the time.The Nice white text on blue reminds me of my old Commodore 64 :3 (wish I never sold the damn thing when I was a stupid teenager, I could be playing turrican right now )
The Large one marked V1.1.1 appears to be a 64MB Flash Chip
The EtronTech Chip is 16MB Ram and its datasheet is here: http://www.etron.com/manager/uploads/EM ... S_v1.4.pdf
The first line from the 1.0.01 firmware update appears as so: Medeli Electronics Co., Ltd.....AKAI MPX8.......V1.1.01.........20130609........SEL+....VAL+....................Data Number.é...A2_ISP.BIN......................A2..........A2..1MB.ini
Right now I'm poking around in the device's boot firmware, there might be a possibility to expand its Midi Implementation, install more ram for samples, Use MPEG Encoded samples (mp2, mp3), decrease load times, turn into a USB sound card, Maybe turn it into a simon says game, make it do the funky chicken, etc.
Select - and Volume- at power on brings you to the factory reset then the test mode.
Select+ and Volume + at power brings up the SD Firmware update mode.
Hope this is at least even remotely interesting to you.
