Why is my Grandmother’s sine LFO doing this?

[starsixnine]

For some reason my sine wave on the LFO is now a half sine wave!

It looks like the resent sync is being used, but nothing is patched in to the Grandmother.

The wave looks the same when I speed it up or slow it down.

All the other waves look normal.

Is there something I might have accidentally done in the configuration settings or would this be a malfunction that needs repair?

Anyone ever see this?

[pmumble]

I would try a calibration. I don't see any way to get the result you are normally.

Hold SHIFT and HARD SYNC for one second to enter Global Edit Mode.
Hold down the PLAY, HOLD, and TAP buttons and press the lowest note on the keyboard.
