I had the same sound with the Novation Sunmit and the Hydrasynth Deluxe. It was driving me mad. It was the TRS cables. Once I swapped to better quality audio cables, the sound went away.
So I tried 3 different cables and the sound didn't go away however I tried switching from the headphone out to the instrument out and the sound went away. I was thinking that the plus of the headphone out was that it would be stereo, but not if it has that hum. Thanks for the suggestions that led to the solution!
Not a great solution but you can just clock the Pam’s with the hydrasynth. Pam clocks pretty well. I’m sure the hydrasynth has a steady clock, though I haven’t tried it. Then you’d have a tap tempo Pam’s! Haha
@@allweatherhaulage that’s a good idea. Just gotta set the clock input in the hermod to whichever usb or midi input you use from the hydra. Then you can clock Pam from the hermod if you still want the synced modulation
