Using only a single stereo S/PDIF output from your audio interface, you can access up to five ES-4 gate expander modules - each of which supports eight gate outputs. That's 40 outputs! All this flexibility is easily accessed with Expert Sleeper's new native Max es4encoder~ object. It couldn't be simpler.
The five eight bit outputs can be used in a number of different ways. Instead of eight gates, an output can send another single 8-bit message like pitch CV or velocity.
