HALion Sonic SE Making weird bass sounds when loading a sound

Whenever I add HALion Sonic SE either as Midi or as Instrument I get this weird rumbling sound that goes off at a steady tempo, like timpani at a steady rhythm, making it impossible to record.
Sound comes out but that rumble is always pressent (the pattern changes depending on the sound selected).
I use a Novation 61SL MkIII connected via usb to the computer.

Maybe use the Midi Insert called “Midi Monitor” to see what your Novation keyboard is sending to the track?

Might be some very low notes that are intended to be control messages not actual notes.

If you’re seeing extra notes that you didn’t play, check if you may need to disable one of the Midi ports of the Novation from “All Midi Inputs”.
