Europa 2.0 for the Roland Jupiter-6

"What features are new to Version 2.0?

# Expanded Patch Memory
Version 2.0 increases the internal patch and preset storage by 6 times, to a total of 288 patches and 192 presets. Each bank of 48 patches and 32 presets is accessible via the front panel or a standard MIDI Bank Select message. The upper and lower splits can use patches from different banks if desired.

# Multiple Undo function for Patch Editing
Unwanted changes to patches can be undone at the push of a button. Up to 127 button presses, 84 slider moves, or some intermediate combination of the two can be undone or redone, until a patch is saved or a new patch is selected.

# Layer Mode
Layer mode allows the upper and lower patches to be played from the keyboard at the same time, while being edited individually or simultaneously. In Layer mode, the lower synth has 2 voices,and the upper 4 voices.

# Keyboard Transpose
Version 2.0 allows the upper & lower splits to be transposed independently. Held arpeggios can be transposed on the fly for many creative performance possibilities.

# Support for Midi Song Position Pointer
The arpeggiator will start at the beginning of the next measure when a song position pointer message is received."
