MIDI Matrix Patch Bay – Part 2

Here are the build notes for my MIDI Matrix Patch Bay PCBs. This post is in two parts (below) covering the two boards required. A further part will consider the mechanical build issues. Recall that there is a mistake in the first version of the OUTPUT boards. Although in the design I've presented the fixed … Continue reading MIDI Matrix Patch Bay – Part 2 →

MIDI Matrix Patch Bay

As my collection of instruments and projects grows, I find myself plugging and unplugging MIDI cables quite a bit and although I've experimenting with a number of MIDI routers, sometimes I just need a relatively simple way of switching MIDI connections in and out. This is another one of my "think while doing" projects - … Continue reading MIDI Matrix Patch Bay →

XIAO Pi USB MIDI Device PCB

One thing missing from a MiniDexed build is USB device support. The Raspberry Pi will act as a USB host to USB devices, but the MiniDexed can't be plugged into another USB host. Some versions of the Raspberry Pi (notably the zero and 3A+) support USB On The Go (OTG) which means they can act … Continue reading XIAO Pi USB MIDI Device PCB →

Tactile Button Keyboard PCB

I've used tactile buttons as musical keyboards in a number of my projects now and either build them on solderless breadboard, which is quite unreliable, or on stripboard, which is a little messy. This PCB design is for a one-octave tactile button keyboard PCB that has various modes of operation and is extendable to two … Continue reading Tactile Button Keyboard PCB →
