Does anyone know if it is normal for a C64 to produce sharp notes? This should be A4 @ 440 Hz, but it is high. (All the notes are sharp.)

This is generated with an ArmSID and Qwertuoso.

Facepalm. It's because Quertuoso calculates the values based on PAL, and I'm using an NTSC machine.

@48kRAM Yeah. Thing is, I even read an old comment on the tool's page about not supporting NTSC.

But because the screen was fine, I assumed it was updated.

Thankfully RJ sent me some math to prove it.
