Midi in/out ports as Scott pointed out.  Usb midi.   Midi in can be sent to usb out or usb in can be sent to midi out.  

Sliders, knobs, pedals and wheels are assignable to midi CC's and can target 2 midi CC's at once with the ability to program a min/max operating range.

4 fully independent zones with independent midi out on/off, usb out on/off and local off/on.  

4 independent arpeggiators with control change capability per step, assignable to the same CC's as the sliders. 

Stage settings that store all of this in memory for recall anytime. 

Plus a few things I'm probably forgetting.  Midi Rx filters, midi transpose per zone, midi octave shift per zone, etc.

Thanks for the info Brad.

Can the pedals on the PX-150 be sent as a MIDI CC over USB?

If you are doing midi controller work, the PX-5s is the choice.  It's immensely more powerful and flexible as a controller.  

Is that just because it has knobs and sliders or is there another aspect of it?

Thanks very much for the welcome and answer.

I really fancy the PX5S actually but it's good to know the cheaper alternative of controlling my existing module and/or VSTs with the PX-150 will give me just as good keys.

Is it true that the PX-150 and PX5s have the same keys?

If they were both connected to an external sound source via MIDI with the onboard sounds disabled, would they feel the same?
