Re: CEM3340 Pulse Oscillation Issue

Just to confirm; I have had the same issues with CEM3340 some years ago: The oscillating pulse edges, much noticed in LFO mode: Adding hysteresis to the PWM input fixed it. Pretty obvious once you think it over. The pitch modulation with PWM: Removed the resistors on the power rails. Shouldn't be th...

I'm currently building an additional cabinet for the modules that did not fit in my EHS 3P . It will be one row of 15 modules. Will probably build the last panel, CV/Gate Bus, this weekend.

I actually ordered this very pot, but when receiving it I noticed that the fourth pin was not connected to anything. :mad:
Waiting for a replacement from Mouser now...

Potentiometers with center tap, where buy?

Hi.
As the subject says. I have difficult to find any supplier of pots with center tap.
Any hints?

Hi. You really don't need anything fancy to attenuate the final output to a level suitable for your DAW or whatever. A passive attenuator (i.e. a potentiometer) or a simple mixer module will do just right. I use my own Mixer/Attenuator module as a final output mixer. http://hem.bredband.net/elmuced/...

I made the layout. A friend of mine milled and drilled the panels.
I painted them. A pro made the silkscreening.

Hi all! Been away for a while... Now: I want to control loop on/off with a HW switch instead of the loop value in the config file. Connecting a switch to a free GPIO. But the firmware... I'm not a programmer. Is there anyone here that could do a hero's deed and tell me how to modify the code? Please?
