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/UI assign modes

The bank (A-F) and number (1-8) buttons allow setting of various options on the arpeggiator when the arpeggiator’s up and down buttons are held. Details on their settings and operation are documented in Chapter 9 (Arpeggiator).

Arpeggiator up/down button differences

The original Roland code required both the up and down buttons to be held to set the arpeggiator’s leadoff direction. With Europa, pressing either up or down alone will turn on or off the arpeggiator and/or set the leadoff direction.

VCO-1/VCO-2 Waveform select buttons

The VCO-1/VCO-2waveform 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

The original Roland code did not allow the VCO sync buttons to be synchronized to each other. Europa allows this. The net effect is a fatter and heavily detuned oscillator sync.

Writing patches (patch protect nonexistent)

Writing a patch with Europa requires pressing write, the bank, and the number (twice). Europa does not include the single patch write protect feature that exists in the Roland code.

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 was pressed.
