A multimode delay line oscillator can be
achieved by introducing a peaked gain response at the required overtone.

How? A tuned filter? There's a hole in the bucket... (circular
implementation)

Alternatively with more than 360 degrees phase shift the oscillation
which cannot change frequency instantaneously can be induced by
continuously increasing phase and jumping from 360 to 0 degrees to sweep
over multimodes.

Wha? Could you expand on that?

Thanks
