Complex resonator.
A complex resonator consists of two complex numbers- one is an absolute phase and amplitude and the other is a relative (differential) frequency and decay/grow factor.

Set unit frequency, amplitude, unit phase, and decay/grow factor.
The phase state will be rewound 1 iteration so the first function call will return a complex number at the desired phase.
