A sine-wave audio oscillator whose pitch is driven by a control input while its level is set by a single Amplitude parameter (0 to 1, default 0.8). The control input sets the oscillator's frequency, so the pitch can be swept in real time from envelopes, LFOs or other control-domain blocks, giving a simple controllable tone source.
The oscillator reads a precomputed sine wavetable, pre-scaled by the Amplitude setting; each sample-frame it emits the current table value and advances its read position by the amount given on the frequency control input. Emitting exactly one sample per tick keeps it inside WaveWarp's sample-per-sample engine, which is what lets the frequency track the control signal sample by sample.
