Disting EX interferes with Plaits

Post by synth.void » Mon May 11, 2020 5:24 am

I started a topic in the eurorack forum, but it feels more relevant here now. The gist of it: plaits is being modulated by the Disting EX in a weird way in the doepfer case (LC9 PSU3). I wasn't able to reproduce that in the other case I have, which is powered by uZeus.

Here's a video:



I haven't tried changing the position of the select bus jumper on the disting just yet - it's not clear from the manual which position does what.

Appreciate any advice.

Does the Plaits get a CV from the bus? If not, that's unlikely to be the issue. If it does, try changing the disting EX jumper.

Otherwise, it looks like the PSU it struggling to maintain the rails properly.

Thanks for getting back so quickly. No, plaits doesn't use the bus. Will measure the PSU voltage later today.

Measuring the voltage with a multimeter is unlikely to be informative. You want an oscilloscope on there ideally.

Still, worth a try.

Yes, you were right. Multimeter shows 12.05V on +12, 5.05V on +5 and 11.93 on the -12V, nothing criminal. I guess it's time to get an oscilloscope.
