Really cool design and concept! I might attempt this myself, thanks alot for the amazing tutorial.

[@ChainSideTV]

BTW also thanks alot for your video on the velostat pressure sensor, I'm making a (singular) MPC style pad as I am watching this video!!

You're very welcome!

So does flexing the ballon add more light into the membrane which is how you measure the the velocity? Is it distance or light?? Thank you so much!

can you tell me how does the performance of this membrane tech compares to a piezo one while building a percussion instrument?

[@bicrome]

With the membrane, you send a note ON when you press and it sends a note OFF when you release it. With a piezo when you hit it, it sends a note ON and almost immediately sends note OFF. Some nice things about the membrane are that you can control the velocity (14:14) and you can play virtual instruments that play musical notes, but for me it is a bit awkward to use circular sensors. You can put the piezo inside a box or inside a 3d printed square (you can make the shape you want). Piezos are perfect for percussion instruments (kzbin.info/www/bejne/bH-6e5Zprct4oJY), but not for note instruments.

Hard to compare their "performance", because they're so different. Main difference is that a typical piezo disk sensor responds to deformation of fractions of a millimeter, where as the membrane based sensor allows much more movement. So playing a typical MIDI drum kit (piezo based) feels like playing an impact sensitive static surface, the membrane instrument is very flexible and responds to the depth of your touch. I'd say it's not better or worse, just very different.

Sir, please make midi ribbon controller

[@KontinuumLAB]

Sorry, I have no plans to make that right now
