"This module is a mixer, 8 stage sequencer, two 4 stage sequencers and a sequential switch.
Functionally based on the core of the ARP2500 1050 mixer sequencer."

"This module is based on the Arp 1050 mix sequencer. Although this version drops the VCO and push button functions. Using the switches, it is an 8 step sequencer, two 4 step sequencers, an 8 input mixer, 8 stage sequential switch, two 4 stage sequential switches and there is also a difference rectifier giving the +ve and -ve difference between stages 1-4 and 5-8.
The assembled PCB shown was a proto-type but the sockets should all be on the same side and the LEDs are actually thru-hole. I just used smd LEDs as they are easy to remove.
It is pretty much all SOIC and 0805 components, but a pretty easy build.
PCB - US$22, 16HP panel US$30, assembled - US$220"
