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).

Arpeggiator up/down button differences

Arpeggiator up/down button differences
The original Roland code required both the up

and down

down

buttons to be held to set the arpeggiator’s

leadoff direction. With Europa, pressing either up

or down

down

alone will turn on or off the arpeggiator

and/or set the leadoff direction.

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.

VCO Sync buttons

VCO Sync buttons
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.

not include the single patch write protect feature that exists in the Roland code.

Writing patches with memory protect on blinks entire board

Writing patches with memory protect on blinks entire board
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

write

was pressed.
