After looking at the driver PCB the tune pot might be backwards.... I plan on trying it tonight and I will report back.... Sorry.

I confirmed that the Tune pot on the driver reacts backwards... Turning CW the pitch goes down and CCW the pitch goes up. I'm in the process of adjusting the gerber files to apply the fix. Literally it is just swapping to pads.

If you already ordered your PCB's it's a simple fix. Just 2 trace cuts and 2 oops wires. I'll post a picture of the modification I did on mine a little later. Sorry guys...

Here is the fix for the tuning pot. This only applies to the original version of the driver PCB. If you are using the gerbers below the fix was already added.

No big deal. As long as it's documented, little adjustments like this shouldn't impact even a ham-fisted solderer like me.

I have ordered the PCBs for the EU-zone today.
The order is based on the latest Gerbers.
If you want to know if you are on the order and the amount please check page 29 where you find an updated list.
I will calculate the exact price and send everyone on the list a PM.

I finished building up my 2nd and 3rd cores this weekend and they turned out great.

I was also able to get them calibrated. I was able to get they to track over 5 octaves with barely any turned of the trimmers. Now I just need to finished wiring everything up and I will post some demos.

oberkorn, that is nice. Looks like Euro banana, is that right? I have a draft panel on ModularGrid, might play around with it a bit.
