Hum problem on LP - Both on main output & HPs

[mikeheavyfeet]

I've had a LP Stage (non USB) for a 2-3 years and record sounds from the main output every 3-4 weeks.

Of late it seems to have developed a sort of ground hum noise, which whilst the synth is played around octave 1 doesn't really become present through the main output or headphones, but when you go up to octave 2,3,4 etc it becomes very apparent that there is the hum is still present, at the same pitch, under every note, on every sound.

I thought that restoring the LP to factory settings would sort this out, however it hasn't! So, I still have the hum problem, and have now lost all my favourite sounds, so a massive loose loose.

Please note: This hum is coming through the main output AND the headphone output.

Any help would be hugely appreciated folks!

Thanks,
Mike

could be the headphones themselves. Have you tried different headphones?
