Custom Barton Musical Circuits CV Arpeggiator + Expander
A very cool little circuit for turning single notes into arpeggios in your modular synth. It features controls for range, note sets, and movement. It contains a built in clock with outputs for triggers and gates, and can also be controlled by external clocks.
There is an expander PCB that allows for external control voltage to be used on any of the stages and adds more control on the note set.

Clock Divider (1/2/3/4/8/16/32/64) under CV control
1-5 Octave Range
Modes: Up/Down, Up Repeat, Down Repeat, Pendulum, Up & Stay, Down & Stay, Random
