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.
