Subject:Numa Tonewheel Model Replacement - Success!

I got a Numa today and after the requisite messing around and using it at
rehearsal, I decided to take a shot at seeing if I could swap out the stock C3
tonewheel set with one of the ones on the KeyB site. Elvio has long claimed it
is possible but I hadn't read where anyone had tried it.

In short, it is possible. It's not even that hard.

You need to have the Numa Updater software downloaded onto your PC (I don't know
of a Mac version). This can be found in the files section of the group along
with the updated Numa operating system. This folder also contains the stock C3
leakage and level files.

What you are swapping out are the leakage (.tlk) and level (.tlv) files for each
modeled tonewheel set. These alternate sets can be found on the KeyB Organ
support page here:

h**p://www.keyborgan.com/support/ - "http"

(As of this writing, the KeyB Organ site appears to be down.)

On the KeyB site, there are leakage and level files for a B3, C3 (probably the
same as in the Numa), an A100 and an RT3. Download these and put them where you
can easily find them. I placed all the leakage files together and all the level
files together.

Hook up your Numa to your PC via the mini-USB (assuming you have downloaded the
USB driver software). When your computer sees it, open the Studiologic Numa
Updater software. On this GUI screen will be four buttons - System, Sound
Engine, Levels and Leakage. Click on the "Levels" button. The Windows File
Manager will open up and ask you to find a .tlv file. Navigate to wherever you
stored the levels files and select one of them. If you have the Numa hooked up
to speakers, you will hear a slight hum and the blue progress bar on the Numa
Loader GUI will show the progress. You will then get an upload complete message.
It will instruct you to restart your Numa but you don't have to do that yet.
Click on the "Leakage" button and repeat the process. When that is complete,
restart the Numa and you should be good to go. (Every time you want to switch
out a set, you have to restart the program.)

The differences between the tonewheel sets are subtle - definitely not
night-and-day. You will probably hear a difference in the depth of chorus and
definitely in the volume level of the percussion. It seemed to my ears during my
brief comparisons that the stock C3 has the lowest level of 3rd percussion of
all the sets. (The Numa definitely needs an update to give the user control over
the percussion levels). Since I only got the Numa a few hours ago, my ears
aren't accustomed to what the stock tonewheel set sounds like, so I wasn't as
readily able to hear a big difference between them. I am sure that I will hear
more of a difference once I spend time with the Numa and get accustomed to its
personality. (I am sure I would instantly hear the difference if you could swap
tonewheel sets in the Nord Electro 3, for instance). If you really want to hear
the obvious difference between a coupe of the sets, set the drawbars to
838000000, listen to the stock tone as you walk a bass line, then swap out the
C3 set for the RT3 set. Very obvious difference.

So, if you are a Numa owner, have a PC, can get the files from the KeyB site and
are up for a little tweaking, have at it! Let me know if you have any questions.
I will try to answer them. If it is ok with Elvio, I could post the sets in the
files section of the group since the KeyB site is down. I don't want to do that
without permission though.
