LE STRUM - MIDI Strummed Chord Controller Kit

Published on Jun 16, 2013

"If you could breed an Omnichord with a Stylophone you might end up with some of these babies.... [or the Oberheim Strummer]

Use combinations of the buttons to select a chord type (maj, min, 7, maj7, min7, dim, aug) and root note. The chord is then mapped across the pads, which you play with a wired stylus, sending output by MIDI.

This is an old idea of mine that I've now turned into an open hardware kit, so anyone can make one. The updated firmware has some new goodies like guitar open chord fingerings, chord variations (sus4, add6, add9), two channel lead + chord drone and control over velocity.

Kit is available for purchase on Tindie at https://www.tindie.com/products/hotch... and the firmware/hardware source code is on GitHub at https://github.com/hotchk155/Voici-Le..."

midihub++ kit: 6 way MIDI splitter and beat clock distributor

Published on Jan 29, 2013 Jason Hotchkiss·115 videos

"This is a kit I have developed from a previous project. The original idea was a gizmo for MIDI jam sessions where several musicians might share a common beat clock accessible to all. The same device also does a 6-way MIDI thru/split so its a pretty handy thing to have.

On board there is a PIC16F688 MCU, a 6N138 opto-isolator and a 4050 six-way non-inverting buffer chip. The PIC handles both the beat clock and the MIDI thru, so there is no contention between the two. Power is via a mini USB socket.

I decided to get some PCBs made up and make an inexpensive kit available on Tindie.
