JX-8P: Comparable Sound Module
The closest sound module to the JX-8P keyboard is the MKS-70 Super JX module.
It is the functional equivalent of two JX-8P's combined together into one unit
without the keyboard. Each of the two JX-8P type tone generators have their own
set of 6 voices and their own sound design parameters. These two sections can
be layered or split. You can even set them to receive on two different MIDI
channels. The MKS-70 can respond in MONO mode for use with a MIDI guitar
