Topic: Home or stage digital pianos which have an external audio input?
So my idea is: buy a fairly cheap second-hand digital piano and plug in Pianoteq to use the piano's internal amp and speakers. But, I don't know which models have an external input. Does anybody know of any? Of course it needs MIDI out too (or USB, but that's not there on older pianos).
I used to have a Yamaha P-150, and that did have audio input, so they do exist.
