time flies like two years almost Shocked

I did breadboard the original design last year but couldn't see a use for it.
Slow_Riot's inclination for LFO use didn't seem that special.

Recent threads elsewhere, have got me to thinking about a One Operator FM module. Initially I thought of a LM13700 for an out VCA and a pitch in VCA. On further consideration perhaps LDR control is more in keeping with the simplicity.

The module could then hopefully be combined in cascade/mix with other OOFMMs (!) etc to generate FM percussion and drones with suitable EGs.
