Figure 2 – Oversimplified Europa arpeggiator, clocking, and voice assign structure
This is a far more flexible architecture. It allows the arpeggiator to be clocked from MIDI, the arpeggiator
to drive the voice assignment, and arpeggiator notes to be transmitted via MIDI! The highly detailed
Europa arpeggiator/voice architecture and operation is documented in Chapter 9 (Arpeggiator, page 30).

The original Roland code required both the up

up and down
downdown
down buttons to be held to set the arpeggiator’s
leadoff direction. With Europa, pressing either up

up or down
downdown
down alone will turn on or off the arpeggiator
and/or set the leadoff direction.

2 waveform select buttons with the original Roland code required the end user to
hold down on all desired waveforms. Many users of the Jupiter 6 did not know that more than one
waveform could be enabled simultaneously due to this clumsy interface. Europa allows toggling of these
waveforms by just pressing the desired waveform button. It will not clear other waveforms when a
single waveform is pressed.

The original Roland code did not allow the VCO sync

VCO sync buttons to be synchronized to each other. Europa
allows this. The net effect is a fatter and heavily detuned oscillator sync.

If a patch or preset write is attempted with memory protect on, Europa will blink all of the processor
controlled LEDs on the board. This is an extremely visible reminder to the end user that memory protect
is on. The original Roland code would not do anything when write
