LFO: read through table. Same as a [phasor~] in Pd, which allows for a LFO/VCO with custom waveform. Alternatively, it could be CV in for controlling the frequency of the LFO/VCO V/oct (or similar).
EG: it will behave exactly the same as LFO in the first case ("phasor"), but should do nothing in "V/oct" mode.
think about how that behaves for different modes:
