Overview The goal of this project for me is to learn more about midi protocol, and venture into ableton live remote midi scripts. This is a basic transport controller for ableton live, but it can be used for any DAW if you manually map the controls to the CC numbers sent by the arduino. The downside of using the arduino nano is that it uses a usb to serial chip to be able to program the atmega328p. As a result of this it requires the use of a serial to midi bridge to be able to communicate with midi devices. I used Hairless MIDI < - > Serial bridge to do this, which can be found here  https://projectgus.github.io/hairless-midiserial/ . If using windows you will also need some sort of virtual midi port to be able to route the midi messages to ableton, the one I use can be found here  http://www.tobias-erichsen.de/software/loopmidi.html . I only use windows so I'm not sure what needs to be done for mac or linux. The next version I work on will use atmega328u4 wh...

Overview The purpose of this project was as a test to see if the 4051 mux would be usable in audio switching. I've been designing a programmable guitar pedal switcher and used this as a test project to see if there were any fatal issues with using them for this purpose. I also had some attiny85s around and hadn't found a project for them. Being able to use two pins to control the select lines of 3 muxes was a perfect use case. In a future iteration I'll try the 4052 mux, the only reason I didn't use one this time is because I didn't have any, and I have heaps of 4051s lying around. Bill of Materials Attiny85 3 x 4051 Multiplexers 2 x Momentary buttons 4 x Leds 5 x Stereo sockets 1 x 7805 Voltage regulator 2 x 10uF electrolytic capacitors 3 x 1k resistors Code The code for this is pretty basic, and self explanatory, with the attiny only using 2 inputs and 2 outputs. Each of the buttons either increments or decrements the current channel. Since ...
