Re: [xpantastic] Xpander CPU Board

2012-09-24 by Do It Yourself Synth

Thank you very much for your help. So I know the version number trick is normal. I have to work on the RAM problem.
My first goal is first to do a 'basic' Xpander. I'll will try updating the firmware later.. ;-)

PS : you are french (free.fr) like me. I'm living in Issy les Moulineaux (near Paris).

Hi,

That's really a good news.
Here the results with my Xpander:

* With the voice board PLUGGED, I have:
MAIN PROCESSOR: 1.2
VOICE VERSION: 1.6 (this is a special case, I think I have a Matrix-12 voice board into my Xpander)
CASETTE: 1.0

* With the voice board UNPLUGGED, I have:
All LED are light up
Display showing : "VOICE PROCESSOR MALFUNCTION"
MEM test: all OK (RAM and ROM)
VMEM: shows "TESTING" and hang the synth. When switched off/on, the synth is still blocked, I needed to do an hardware reset (turn on while keeping the finger on "CLEAR").

MAIN PROCESSOR: 1.2
VOICE VERSION: 2.0
CASETTE: 4.4

BTW, I'm the author of the Xplorer editor (http://xplorer-editor.com ). If you plan to add some functionalities through MIDI, I'll be glad to include them into Xplorer. please let me know.
