Just fyi...if anyone is looking for something a little cleaner than the stacked tape fix. I made 3 vertical strips from the 4 dollar shelf liner available at IKEA.
Here is a picture of the dimpled texture.
http://jupiterbuttons.files.wordpress.c ... indow3.jpgI have the dimples going up towards the bottom of the pad.
I tested the raw sensor vs the insert and I feel no difference in terms of triggering time or velocity sensitivity. The only difference is that you are simply putting your finger on a semi soft button. No extra force needed and no change to the MPC itself. I do feel like the MPC is complete now in terms of function.
It is my impression from watching the material under the pad that the dimples diffuse the pressure somewhat over the entire sensor surface. So a reduced amount of pressure averaged over the whole sensor area with miniscule clearance adds up to a nice solid contact.
I only A/B'ed against a piece of plastic record sleeve and raw...but once I tested this material I was done.
So next time you're at IKEA swing by the kitchen dept.
Even if you are someone who is comfortable with the pads as is...I still recommend it. It just feels very finished to the touch. If you sell it just take them out for stock.
Now all I need is Audio In soft thru....

Take care,
Pete
