Actually MIDI Expression iO Manual mentions its 'computer independency' when USB powered. By looking around I found also this: http://www.kentonuk.com/products/items/utilities/usb-host.shtml which can do the work when already owing a MIDI Expression (non iO). But, it comes for 88.80 UK£, thus the iO is the real solution for 3 continuous pedals. For a single-expression pedal need: US$ 219 https://www.sourceaudiostore.net/product/reflex-universal-expression-controller which is (maybe) an 'all-inclusive' solution or, cheaper, MIDI Expression (US$ 49) + USB-Host (about US$ 100) + the pedal (today down to about US$ 30). I still hope to find a better solution, although it is likely that MIDI Expression iO (as I already own two expression pedals and a continuous sustain pedal) is the stronger option today.

Dear TLc, I am very interested to know what was your solution to the Midi Expression problem. I have a PX-5S myself and I found quite a complex route bu usong IK Blueboard, an iPad and a iRig MIDI to enter the keyboard. Thank you in advance for your reply. Alberto
