JX-3P: Comparable Sound Module

Tags: jx-3p
The closest sound module to the JX-3P keyboard is the MKS-30 Planet S module.
It has the same sound source plus a few additional features. For example, the
MKS-30 responds to velocity and aftertouch messages whereas the JX-3P does not.
The MKS-30 also has a cartridge slot for storing and adding new sounds.
