Very interesting and amusing, and well played!
The keyboard looks similar to a https://en.wikipedia.org/wiki/Jank%C3%B3_keyboard , which maybe was just ahead of its time.
I am wondering how good is the touch sensitivity compared to a real keyboard?

Thanks so much!  The touch sensitivity is very good.  It's may be slightly more challenging to control in subtle ways compared to a good standard keyboard setup, but it is really quite good in that regard.

Hi reckon!
Interesting! Very nice! Midi controller - at first I thought it was a program for iPad :-)  Sounds great with Bechstein, and your special way of playing those chords. It really sounds beautiful. I was thinking how your way of playing sounds with Organteq? Waiting for more videos Ptq/Orgtq. Thank you for sharing.

Thanks so much for the kinds words.  At some point I'd love to get Organteq!  I know it's amazing and would love to spend time with it.  Maybe someday!

Thought some folks here might find this interesting, or at least amusing
