Controls and Operation

Apart from the 16 potentiometers and/or switches that are connected to JP1 and JP2 PE has
these controls available:

• momentary switch/button (connected to ST1, please refer to page 10)

• LED (connected to ST1, please refer to page 10)

• 8 pin DIP switch (please refer to page 10)

Functions of the LED

After power on the LED will stay lit for around one second when the power is first applied to the
PE . If this does not happen probably the power supply used is not suitable (i.e. correct polarity,
voltage and current) or defective.

Under normal operation the LED indicates MIDI input activity, and also MIDI output activity
when moving the potentiometers or operating the switches connected to PE .

The LED also indicates these situations:

• The status of the Snapshot function (details see "functions of the button")

• Data and status when setting the Master channel

• Indication that a preset has been changed

• Any error at the MIDI input

• Whenever an overflow at the Midi input is recognized by PE the LED turns permanently on.

This is an indication that the merge capacity of PE has been exceeded, or that SysEx
messages intended for PE have been transmitted too fast. In both cases the Midi data have
been probably received or transmitted incomplete. If applicable the data rate at the Midi input
of PE has to be reduced as PE is not able to process high Midi date rates (e.g. a complex
Midi sequence sent by a sequencer). To clear the error the button has to be operated
(details see "functions of the button")

Functions of the button (momentary switch)

The button has various functions:

• to send a "snapshot"

The snapshot function is not achieved by just pressing the snapshot switch, as this could be
accidentally pressed too easily. So to activate the snapshot function, first briefly press the
switch once, this causes the LED to flash, the switch needs to be pressed again within at
least one second (whilst the LED is still flashing). This then invokes the snapshot function,
and the data from all 16 inputs is transmitted from the PE.

• to set the master Midi channel
