Arpeggiator Europa User Guide

Internal clock (A)

The arpeggiator is clocked from Europa’s internally generated clock. The rate is settable via the RATE knob on the front panel (under the ARPEGGIO section of the front panel). This selection will generate a standard 24 PPQN MIDI clock.

External clock (B)

This setting synchronizes the arpeggiator to the external clock on the back of the Jupiter 6. The arpeggiator is clocked at one step per pulse, just like the Roland code. This selection will generate a standard 24 PPQN MIDI clock.

MIDI Clock (C)

The arpeggiator is synchronized to the incoming MIDI clock at a rate of 24 pulses per step (PPQN). The arpeggiator’s standard stepping is on a eighth note basis. MIDI Clock (unlike internal and external settings) will NOT be transmitted when synchronized to an external MIDI clock source.

External and MIDI clock sources can be multiplied and divided by the setting of the multiplier/divider and by polyrhythm. The arpeggiator needs a regular interval clock to function properly at any multiplier/divider setting other than 1X or if polyrhythm is enabled. Gradual changes will be tracked and followed, but uneven, irregular, or sudden drops in clock pulses from any source will yield unpredictable behavior. This does not apply when the arpeggiator is synchronized to the internal clock.

MIDI Clock transmit (D)

Controls whether or not Europa transmits MIDI clock when synchronized to the internal or external clock sources. MIDI Clock is not transmitted when the arpeggiator is synchronized to MIDI clock.

Button E is not used and has no action when pressed.

Polyrhythm setting (F)

Polyrhythm evenly divides the number of steps per clock by the number of currently held notes. Holding a single note would play one note per step, holding two notes would play two notes per step, etc… up to a maximum of 16 notes with the time evenly divided between the notes. If the 17th note is played, the polyrhythm mode will revert to operating as if one note is held. At high tempos with many notes held, the effect is more like an LFO modulating a VCO than it is of distinct notes being played. At extreme tempos, the arpeggiator will not have time to transmit the voice allocation requests to the voice boards and will revert to operating as if only one note is held.

Polyrhythm is an independently enableable feature on a per-SPLITbasis. The polyrhythm enable is saved with the preset edit.

Multiplier/divider settings (1 - 8)

The 1-8buttons select a multiplier (buttons 1- 4) or a divider (buttons 5-8) on the incoming step clock. Only one of the eight options can be set. The multiplier/divider is independently selectable for both the upper and lower SPLITS (when in SPLIT mode) and is saved with the preset edit.

Arpeggiator mode and options

Arpeggiator mode and options are selected by pressing the UP button and holding it for more than 1 second. Buttons A-Fand1-8then have the meaning as shown in Figure 10.
