Dump currently edited patch to MIDI (5)

This will dump the current patch edit to MIDI via Europa’s system exclusive patch dump message. If the board is in SPLIT mode, the UPPER and LOWER LEDs will determine which patch is dumped. In WHOLE mode, the UPPER patch is dumped. See the System Exclusive operations section for further details on the format of Europa’s system exclusive messages. This feature will function regardless of the system exclusive transmit setting.

Dump currently edited preset to MIDI (6)

Similar to dumping the currently edited patch, this will dump the preset currently being edited to MIDI via Europa’s system exclusive patch dump message. The System Exclusive operations section contains further detail on the format of the preset system exclusive message format. This feature will function regardless of the system exclusive transmit setting.

Dump everything to MIDI (7)

This is effectively a “Save board state”. It will dump all patches in flash, all presets in flash, the current patch and preset edit buffers, and the settings of all board options to MIDI via Europa’s system exclusive messages. Refer to the System Exclusive operations section for further details. This feature will function regardless of the system exclusive transmit setting.

Generate random patch (8)

This is one of the more fun features of Europa – a random patch generator! Executing the random patch generator will cause the currently edited patch to be randomized in the following fashion:

The VCA ENV-2 LEVEL is always set to 127 for maximum output

The following potentiometers/sliders are randomized with an inverse logarithmic response. That is, they most likely will be 0 and least likely to be 127 (maximum). All other potentiometers/sliders are completely random:

LFO Delay

Manual Cross MOD

VCO 1 Range

VCA LFO

ENV-1 Key track

ENV-2 Key track

The VCO-1/VCO-2mixer is center weighted, meaning the most likely values will be near the center with a 50/50 mix split

The filter settings have a 50% chance of being low pass, 25% of being high pass, and 25% of being band pass

All other buttons are completely random, though only valid settings will be chosen

Remember, in synthesis there are more ways to make no sound than a sound. That is why the random patch generator does not randomize all settings – to help minimize the possibility of complete silence. If the generated random patch does not make sound initially, hold down on the key for a few seconds, as attack time may be a bit longer than immediate. If after 10 or so seconds there is no sound or you just get too impatient, press 8 again to create another random patch!

The random patch generator was designed to help guide sound generation rather than being a polished patch. Tweaking of the random patch is encouraged and expected.

Creating a random patch will always transmit a “generate random patch” system exclusive message.
