I want to build a 28 to 30 note steel drum. Ideally it will have velocity sensitive sensors that can be played with light, rubber coated sticks. I think the Arduino Duo is the board I need and then it triggers notes (wav files) in a computer corresponding to each trigger.
Does anybody have any experience with a project like this?
Is the Arduino Duo board the right one for me?
Will the inputs to the Arduino be velocity sensitive?
Can anyone suggest what triggers I should use for the sensors?
Any help would be appreciated and thanks in advance.

Most of the world. Try and google
Arduino drums

Why? I can see no advantage in using a Due for this over anything else.
Thanks for responding the Arduino drums is a cute project, but looks like it will not handle 28 to 30 inputs. I will need a different board. What board do I need for 28 to 30 inputs (separate notes/sounds).

You need a couple of port expanders to get more I/O. The MCP23017 is a good one. It gives you 16 extra inputs per chip, and you can use up to 8 chips.
If you need extra analogue inputs then use a CD74HC4067 chip, this will give you 16 analogue inputs for each analogue input on your board.
If you need digital inputs, go for a Mega, that should be enough for your stuff.
Thank you to the folks that replied. I ended up purchasing a teensy 3.5 and audio shield. So I am now trying to get it pulled together. I may have more issues since the wiring and programming are not clear to me at this point. I am following some guidance from other projects, like the Teensy handpan V2. It's clear what parts are used, but not the hardware connections.
