This section gives a brief overview of how Europa differs from the base Roland user interface and feature
set. Further detail is found in appropriate sections of this document. We have tried to keep Europa’s user
interface as close as possible to the Roland user interface, but several improvements to the user interface
were made. The front panel on the Jupiter 6 is limited, and extending functionality with such limitations
was extremely challenging!

Europa has changed the architecture of how the arpeggiator interfaces to the assign modes. With the
regular Roland code, a user has a choice of the arpeggiator OR the assign mode being enabled as shown
in Figure 1. This means enabling the arpeggiator will disable the voice assign mode, and vice versa:

This is somewhat limiting, as with this architecture it is impossible to arpeggiate any of the voice modes.
For example, arpeggiation with unison mode voice assign sounds cool, but is not possible with the
Roland code! It is possible, however, with Europa (oversimplified architecture shown in Figure 2):
