Thanks! I looked them up. MorphWiz looks amazing. I have no iPad but the videos look neat. I might have oversold my innovation. I have been thinking about haptic pressure as you say, this is the weakness on most devices. I am thinking about maybe using drawing devices for power users. Hey even on a drawing tablet with no display, it could be interesting to try out.

In any case, I did try my app on tablet and it feels great (and responsive on cheap CPU). Forgot to say, that there is a tremolo feature and which is key to expressiveness.

Thanks for the comment, appreciated!
