Before we get to the AudioCentron,
here are a few things I'd be happy if you could help me with:

Maybe you have the card or have downloaded a card image of Roland FANXRUP1 or FANXUP1 Fantom-X V2 update that was once floating around the web? If you have the card but don't know how to create an exact backup of it, I'll help you with it - it's easy.

Although unlikely, maybe you have Roland VP-9000 demo disk demo song files?

Or maybe copied floppy files Casio WK-1800 Accessory Disk (demo disk that came with it)? It doesn't seem to be for download on any casio support and fan sites. You might like the main reason I'm lookig for it - it is clearly a fun attack vector to non-destructively dump its maskrom (in Hitachi H8) since it actually allows to execute arbitrary code! While dumping can be done even by blinking a led chdk-style, in this case there's already initialized and working uart for that. Further, if all is well, waveroms (8Mbyte total) can also be dumped this way, since H8 can quickly access them, and procedure to do this for studying will be in the maskrom. On the other hand, I'll very likely at some point just desolder and dump waveroms anyways - but it could be more epic to dump it via diskette and midi.

I'm looking for an Alesis XT:C rom dump and also Alesis XT-Reverb rom dump, Here's a MidiVerb dump for you in exchange. In fact, you can find tons of my dumped roms on this great webpage.

Also - maybe you have an Alesis Wedge rom dump? Or, at least, have made some photos of its inside?

It seems that Yamaha CS6x/CS6R supplied accessory CD (with old original software and preload audio clips) is not amongst the available support downloads -  maybe you have it and can dump its contents?

It seems there is a Yamaha PSR-40 service manual floating around the web, but I couldn't yet get one. I'd be happy to get PDF of that. That synth, while immensly boring and shallow (despite the "variation" knobs) works on Zilog Z80, so can be made much more fun at some point. (I've, of course, dumped the rom and did a little bit of disassembly for it as well).

Any of the ART MultiVerb, ProVerb or similar reverbs/effect rom dumps are also of interest for me, for example I'm looking for ART Proverb 200 - here's an ART Multiverb LT dump for you in exchange.

It seems that there exists a version 2.02 firmware dump of Lexicon MPX-500 - maybe you have it?

Judging by the immense popularity of PSS-51 in eastern europe, aisa and amongst russians, it is quite hard to believe that no one have dumped its roms. Maybe you have dumps of Yamaha PSS-51 program, abc and/or waveroms? Or maybe you know one for local pickup somewhere within Baltic states?

And maybe someone has already desoldered and dumped PSR-6000 waveroms? Those are three pieces of DIP42 chips, each 2Mbyte (besides two more chips with styles and then two DIP40 with program and demo songs). I am somewhat tempted to grab one from the local trash market to do this, yet not sure if I realy have to. And I don't have a clue when I could actually get to desoldering it, even if I' ll grab one now. Still GEW9 stuff seems rather interesting and not that common to come by in the keyboards.

In regards to spare parts and hardware things that I'm missing, maybe you have this:
* Display from early 2000s - Kyocera KCG057QV1DB-G00 found in old Fantom-X keyboards (Roland part code: 03560889 "DISPLAY UNIT LCD KCG057QV1DB-G00").

If you do, please email me!

Audio Centron FXP

This is some oddball effects processor from 1996, featuring nothing noteworthy in particular: shallow and pale effects, minimum editing.
However, interesting thing about it is that effects, even though are very barebones, it isn't capable to run them at full samplerate. Some effects run aat 48kHz, some at 32kHz, and some at weird 27kHz. Look up respective sample rates for each effects program in the manual below, tile 6 - table of programs.

Hey, nice to see you there reading, but this is still just in a placeholder page stage!

Since it seems to be more likely for me to ever move forward something like this only once it is somewhat "in progress".

AudioCentron FXP dsp
  • Audio Centron FXP runs entirely on ADSP-2105 clocked at 12.288MHz
  • And here's its rom for you.
AudioCentron FXP converter
  • Converter: CS4215-KL
AudioCentron FXP kludge addon
    • Interesting afterthouht kludged on the rear panel - output attenuator pot and a screw have been added in-factory after production. Silkscreen print was not changed, and instead a sticker was added.
AudioCentron FXP kludge addon inside
    • From inside these two holes seem to be almost hand-drilled.

Currently under construction. I am going to fill it up, whenever I will find some spare time for doing it.

Audio Centron Earth Series

"earth tools for a sound planet"

Since it doesn't seem to be available anywhere on the net, here I photographed for now its cardboard manual, but will someday probably scan it as well. Photos (click!) are high enough resolution to be completely readable.

That's it for now!
