BMC26. Rando Chordo
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.

If you'd like to drill your own panel, here is the drill guide that I use to make these panels. It should be printed at 300dpi.
