1. You can use the LP to process any audio signal simply by plugging into the Audio IN jack.
To hear the external audio signal without having to hold down a key on the keyboard, plug a
dummy plug (or a patch cord with nothing connected to the other end) into the KB Gate jack.
This will leave the keyboard gate open, and the volume envelope will remain at its Sustain
level until the keyboard gate closes. Due to the design of the envelope circuits, you will need to
turn the envelope Decay parameter down below 12:00 in order for the Sustain level to remain
constant. If you notice that the volume of the external signal begins to slowly fade away, check
to be sure the envelope Decay parameters are not set too high.
2. The LP’s Audio Input is not limited to processing monophonic signals - it can work well for
processing polyphonic signals, too. For example, connect the MIDI Out of the LP to the MIDI
Input of another polyphonic keyboard, then feed that audio output back into the LP through the
Audio In jack. Now you have a POLYPHONIC source that is being affected by the LP’s Filter,
Overload and EGR circuits.
