MIDI Bass Pedal using Arduino and 3D printer for the keys
« on: April 26, 2017, 08:55:30 PM »
I have started this project. So far I have only printed one key, as a prototype for testing.

For MIDI control I will use one Arduino MEGA.

I am still unsure about the design of the box and how to attach the keys to the box.

I have posted the details on Thingverse.com:

Looks great !!
Are you going to use one switch per key and have fixed velocity, or 2 switches and have key velocity (one switch closes before the other and time measured between switches both closing determines velocity)

Hi Gumtown. Thank you for the tip!! I didn't thought about making it velocity sensitive, but now I am going to consider it.
I didn't even knew that it is actually made with two switches!  :D

The mechanical part will be very easy, just setting two switches at different heights. I'll start modifying the 3D design right now (I am using OpenScad)

Micro-switches are very cheap. I've ordered 20 units for $2.79

What I don't know is if it will be so easy to implement the calculation of the lapse time between the 2 switches in Arduino.

So far my most complex experience with Arduino is this simple and ecologic MIDI controller for the Axe-FX:

I will dig deeper.
