I do see a mention of Alison with the Kepex and GainBrain. They both made strong contributions to the development of signal processing. As a programmable Expander that could be keyed by an external signal opened a number of possibilities that are still being explored.

The RMS settings in the GainBrain was also a unique function for the time.
