Hi!
I recently got a used prophet 12, and have noticed a weird ringing in the sound.
Have not yet been able to locate what generates it, but i'm able to remove it if i turn the high pass filter above value 50.
I can best describe it as a high frequency digital ringing / aliasing, but it seems to stem from low frequency content, and is best heard with the low pass filter turned down low and with mellow sounds.
Have updated os, and calibrated the filters several times but no improvement.
Someone here familiar with the issue, or have similar experiences?
Cheers!

the patch is a bass heavy, low passed pad sound.
