Hi everyone!

I have a problem with Dark energy 2. When it works for various hours i listen a change of the sound. If i play a note don't listen a linear sound but variable, dirty sound and like LFO influenced. Naturally i have exclude all the parameters like LFO.

It's a natural problem or can i solve it?

Thanks

Alessandro

Yes I had this too. Do you have a keyboard with a mod wheel connected? The Dark Energy has a built in LFO (software) that is activated by the Mod wheel and connected to pitch.

Another reason that may cause this behaviour is a faulty external power supply (12V AC/800mA required). If it outputs not enough
voltage or current this may cause ripples of the internal DC voltages which sounds like 50/60Hz FM.
