DIY Gate Output Expander for RYO Penta

GRAM aka Gate Routing Add-on Module is a DIY output expander for the Ryo Penta sequencer.

The module has buffered individual outputs for each of the gate steps and on/off toggle switches to selectively route them to a combined gate out. It has a toggle switch to change the CV output range of Penta from 1V to 2V to 5V (stock). Also a toggle switch and a overvoltage protected input are provided to pause the sequencer on the then-current / active step. All operating voltages are sourced from the Penta module.

Panel is oak wood treated with charcoal dark grey stain, with handdrawn artwork. Listed price is a rough estimate of all parts needed to build the module.
