Get the keyfile 1st !
When I got my,- also used,- NOAH EX some time ago, I had no clue how to bring it up to it´s latest OS version and such.
The seller wasn´t unable to provide a keyfile and useful info.
So I waded thru this NOAH thread here @PlanetZ and was happy to get the keyfiles for the "ancient" machine.
I decided for reflashing the machine 1st, then install latest OS,- and that was it and it works like new.
But you
HAVE to use a
WinXP computer or
Mac OS X 10.2, read everything twice and painstakingly follow the instructions !
Once you reflashed the NOAH successfully, install NOAH v1.1 software.
In Windows XP (SP3), disable driver signing before you do !!!
I didn´t know,- and forgot I also had to do this when installing SCOPE v5.1 on a XP machine,- so the NOAH drivers didn´t install completely, and it cost me a lot of time and nerves to find out why.
But that´s only software...
Before you dive into the software upgrade/update,- you have to be sure the machine´s electronics work flawlessly.
I´ve never seen a "ACK Timeout" message and a NOAH plays the installed and authorized synths even some extras aren´t authorized.
Are you able selecting and loading "single" devices from frontpanel and playing these using a 5-Pin DIN MIDI connected MIDI keyboard ?
Does your NOAH play musically useful sounds at all when receiving MIDI notes and when
NO computer is connected ?
Mine did,- even w/ the oldest OS installed.
The devices don´t sound and work different depending on the OS since NOAH is a hardware device working as it should and w/o a computer.
If not,-
Does the PSU work stable ?
Do the flashmemory modules work as they should ?
Both are important preconditions for a successful reflash procedure.
And,- what do you mean w/ "re-installing the OS" ?
IIRC, the latest firmware comes w/ the flash files.
There are 2 of these,-
"noah_default.dmp" (bringing NOAH to the level when it was released 1st and not including all the extra devices)
"noah_default_edsp_prod.dmp" (incl. the optional devices except Profit5)
The Flashtool,- and depending on your hardware serial number,- one of these files is what you need.
When your "SYSTEM" version is v1.0, 2003-5-6 (check in NOAH system menue),- in Windows there is no USB connectivity at all.
This was the case w/ my NOAH EX.
So, updating the SYSTEM software was essential for further installations and activations using .oxe files and keyfile(s).
And on my NOAH EX, this was only possible after setting NOAH into "miniOS" mode and reflash.
Otherwise and in Windows, there never ever were any reliable working USB connectivity possible.
I have no clue how it works w/ Mac OS X 10.2,- my oldest Macs are MacOS 9.22 and then OS X 10.4.11.
So, I recommend using Windows XP Pro SP2 or SP3.
