I'm surprised in this day and age of internet connected sex toys there isn't generally an option to create or download custom vibration patterns or to configure button settings.
With Lovense you can. Don't know about other internet connected toys.
I recently found out that there's an amazing term for internet-connected sex toys: Teledildonics
Yeah but this only goes so far, just like the difference between a single not synth and polyphonic, maybe more actuators are needed and the interplay of them creates symphonies of haptic like sensation.
With PWM the actuators can have polyphonic waveforms. More actuators is probably a benefit for stimulating different areas and greater overall amplitude, but I imagine a toy with multiple actuators would only benefit more from being able to modify the settings.
