G. Input/Output Panel
The Side Panel provides all of the input
and output connections. In addition to
Audio Input/Output jacks, there are CV
and Gate inputs, connections for MIDI,
and the power connector and power
switch.
Power Connector:
This is a standard AC power inlet, Use only a power cord designed to mate with this receptacle. The Little
Phatty’s built-in universal power supply is designed to work with power inputs of 90-250 Volts AC, 50/60 Hz.
IMPORTANT SAFETY NOTE – Do not alter the power connector in any way. Doing so can
result in the risk of shock, injury or death. Be familiar with the safety instructions printed at the
beginning of this manual. If the connector is damaged, refer servicing to qualified personnel only.
Audio IN:
The Audio In jack allows an external audio source to be mixed with the LP’s VCOs, and then routed to the
filter for processing. The LP has no provisions for adjusting the level of this input, it must be controlled ex-
ternally. The audio input is designed to distort as the level of the external audio gets very high, adding color
to the sound.
Audio OUT:
The Audio Out jack provides an unbalanced line-level signal for connecting to an amplifier or mixer.
CV Inputs:
The Pitch, Filter and Volume CV jacks supply power and will accept an expression pedal such as the
Moogerfooger EP-2 (ring = +5.5 supply to the pedal, tip = variable CV return), or a control voltage from
–5 to +5 Volts.
The KB Gate Input accepts a footswitch (a momentary, normally-closed footswitch like the
Moog FS-1) or a +5 Volt Gate Signal.
MIDI Connectors (DIN and USB):
These are connections for MIDI In/Out. MIDI I/O is configurable for either connection type. For more
information on configuring MIDI, see page 31.
PERFORMANCE TIPS:
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.
