Expert Sleepers ESX-8CV MkII
The ESX-8CV is an expansion module for the ES-4, ES-40 or ES-5, adding eight CV outputs from one expansion header.
In order to squeeze eight 12 bit channels through one 8 bit connection, the channels are time-multiplexed and so effectively run at between one-third and one-twenty fourth of the audio sample rate. For example, if the audio interface/DAW is running at 48kHz, the ESX-8CV's outputs are running at between 16kHz and 2kHz, depending on how many channels are active. This is still plenty fast enough for most CV purposes, except for audio-rate modulation and the very fastest envelopes. Because the outputs are still derived from the audio stream, they retain the advantages of the ES-3/4 over traditional MIDI-based interfaces, that is, rock solid timing and absence of jitter.
