The Java based client for Rocrail.
(Support Key needed.)

RocJ is a Java 5+ Rocrail client targeted to MIDs and Pads.
This client is track plan oriented and can be controlled with just a one (left)button mouse or touch screen.
It does not feature an application menu; All actions are context sensitive.

RocJ is a goody for those who have a valid support key installed on the server:
