Subject: Re: [AN1x] Polyphony in Single mode

Hi Peter
- thanks for the hint.

I opened the AN1x today. It took me some time to spot it, but in act
on the main board there sits another small pcb. That one was sitting a
little bit askew.

After fixing this,everything is fine again.

Apart of the polyphony problem, of course most of the sounds did not
have their full depth.

Now it's an awesome instrument.

Thanks again--

cedrik
