The Bananalogue PROG is a preset manager/programmer/analogue sequencer module, inspired by Arpad Beneres' 1977 design found in Synapse magazine. It combines functions found in the 5-step sequencer and preset voltage sections of the Buchla Music Easel.

The module has five columns, each with a pushbutton, LED indicator, gate input, gate output and four parameter potentiometers. These potentiometers feed four rows of outputs: A, B, C, D. The values of the potentiometers may be accessed by utilizing the pushbutton for a column, by addressing the column's gate input, or by stepping to the column using the sequencer forward or backward gate inputs.

There are two additional outputs, a common gate of the buttons that goes high as long as any button is held down, and a trigger pulse output that is tripped whenever the column is changed.

The PROG CV outputs (A, B, C, D) are 0-10V and could be used to transpose other sequencers, program CV envelope stages, VCO or VCF frequencies, rate of portamento, VCA response etc.
