The Rando Chordo is a specialized quantizer that takes a single CV input and outputs 4 voice CV to create chords. The chords are generated randomly and it has controls over the range of the chord (how far from the root note another note in the chord can be), the musical mode used in quantization, forcing a 5th, allowing inversions, setting whether quantization happens per note or per chord and a sample input to control when the input CV gets sampled. There's a built in tune-mode to help tune your VCOs together.
The board features PC mounted pots for less wiring, and mounting holes for flexibility in panel layout. There are Eurorack and MOTM power connecters. It can be built in +/-12V or +/-15V systems with no modifications.
This MP3 is 3 voice chords with the 4th CV output going to a VCF, as well as an LFO controlling the "New Chord" input and the cutoff of the VCF.
For complete descriptions of the way the module is used, and how to build it, including schematics and parts list; download this PDF file.
Boards are available now. Price for 1 PCB/PIC set is $18.
Unfinished eurorack
panels are available for this project, they are 8HP and cost $8 each.
There is
more information here about panels. If you're interested in drilling your own panel for
this project, feel free to use my
drill guide. That image should be printed at 300dpi for proper
scaling.
