    Update 16/1/31: The Alesis iO Dock has been retired by Alesis. It was replaced by the iO Dock II which is also deprecated. Oh well…   This is definitely something I will look at in detail when it becomes available.I’m already using my iPad with keyboards, microphones and my guitar plugged in. Also, I use…

  • PU-1: Emulating the Apogee Gio, Part 2

    I have completed the second phase of this project. The PU-1 can now send commands to GarageBand/Logic/Mainstage and receive commands and other information using Midi commands (but not from GarageBand). Part 2 did not require more electronics. All additional changes were made in software. WARNING: I first picked up a guitar a few months ago,…

    After days spent trying to find reliable ways to get Midi data from the pedal board to the computer,  and more days trying to get data from the computer to the pedal board, the proverbial shovel finally hit me square in the face. This is what happened: The PU-1 is using an Arduino to process…

    The Apogee GIO is a small pedal board expressly made to interface with Apple’s Garageband or Logic. I use Logic for music production and control, as well as for live performance.   Since the PU-1 is awaiting a purpose in life, I decided to try emulating the functionality of the Apogee GIO. Let’s review the…

    The PU-1 is complete, at least in its prototyping phase. The connection board is done and the external Arduino/Shield is attached. In this picture, the PU-1 is powered by a 9 volt battery. At the top is the Arduino with the connection shield and the connection ribbon. I removed the USB connector from this picture.…

    Time as come to put the Line 6 pedal board back together. I decided to call this particular board the Line 6/PU-1. I hacked it… then it is mine! The behringer FCB1010 will probably be the PU-2… The PU-1 will serve as a test bed for new ideas and prototypes. Each subsystem has already been…

  • Arduino: Using a rotary encoder

    As explained in this post, rotary encoders are notoriously unreliable. Well, the cheap ones are. Why bother? But wait, could they be used at all? Most of the problems people complain about have to do with bouncing. But is bouncing as important if someone is turning a rotary encoder manually to increment a counter? Also,…

    Seven whole days! That’s how long I had to work to finally get my rotary encoder to work with the Arduino! The idea is to be able to quickly select a preset on a guitar pedal board using a rotary encoder instead of a couple of push buttons. The rotary encoder I’m using uses pretty…
