The Kilpatrick format is a new kind of modular synthesizer system
for players that demand something better, different and
inspiring. Designed by Andrew Kilpatrick, the Kilpatrick format
represents a new generation of modular music making by offering the
right combination of look and feel, playability, excellent circuit
design, and the perfect blend of old and new concepts that make the
system easy and fun to use.
Whether you're an experienced synthesist, or looking to get
into synthesizers or modular systems for the first time, the Kilpatrick
system has something to offer you. The clean design is easy to learn,
but also offers experienced users an uncluttered layout that gets
right to making great sounds.
Kilpatrick Format Features:
4U (7") panel height - each panel offers close to 30 in. of
panel space
Simple plug and play module installation - rearranging a system
or adding new modules is easy
Universal use of banana cables for patching of audio, CV and
pulse/gate signals - high quality cables are available in a variety
of colors and lengths
Color-coded jacks indicate different signal functions and
direction
Separate analog and digital grounds used for low noise signal
returns - plenty of power available for digital modules
Total cabinet depth of less than 3" permits table top or rack
mounting
High quality brushed anodized panels are rugged and feature
clean, futuristic graphics
All modules and systems are hand-assembled and built-to-order in
our downtown Toronto workshop
Kilpatrick format products are only available directly from Kilpatrick Audio
Modules
K1 // Mixer Interface
Kilpatrick Format Mixer and MIDI Interface
Combining a compact and capable audio mixer with a MIDI to CV converter the K1 Mixer Interface
acts as the central hub of most systems. The AUX send and stereo inputs provide a perfect effect
loop for use with the K3 Digital Effects module. Both headphones and line outs are provided with
independent volume controls.
A built-in MIDI to CV converter offers many different modes of operation, allowing a MIDI keyboard
or computer to control the system.
A real analog VCO based around a traditional sawtooth core, the K2 Pitch Oscillator generates
multiple basic waveforms simultaneously. The PWM section includes both a standard PWM mode and
a unique multi-pulse mode for making new timbres. The wave blending section allows voltage-controlled
blending between different waveform combinations.
The K3 Digital Effects module offers two independent digital effects processors in a single
module. The REVERB / DELAY section produces high quality stereo reverb and delay effects
processed at 24 bit. The ITTI BITTI section produces lo-fi effects to either audio or control
voltage signals processed at 12 bit. Effects such as digital multiplication, (ring mod) sample
and hold, wave folding and digital distortion are possible.
The K4 Envelope Modulator offers four complete channels of modulation goodness in a single module.
The first two channels generate envelopes in one of three modes, with voltage control over the
up and down times of the envelope. The other two channels generate LFO signals with voltage
controlled speed and a wide range gain control.
The LFOs can be synced together and produce outputs with configurable phase offsets between them.
The K5 Filter Amp is a quad voltage-controlled amplifier (VCA) and low-pass filter (LFP) in a single
module. Manual and voltage control of the output level and filter cutoff frequency are provided on each
channel. Adjustable filter resonance adds extreme peaking around the cutoff frequency for ultra-juicy
bass sounds or pitched percussive sounds.
The K6 Voltage Processor is a workhorse utility module. It has audio buffers to convert
audio signals to and from the outside world. Add to that four mixers each with dual buffered inputs,
gain control, (0-2x gain) normal and inverted outputs and a signal level/polarity LED. It also has
two more mixers each with dual buffered inputs and a normal output plus a level LED and a fixed gain
of 1x. Finally two buffered pot that can make -5V to +5V for creating manual control voltages, plus
a signal switch / swapper which can be either manual or voltage controlled.
Kilpatrick Format Random Sequencer and Analog Noise Source
The K7 Entropy Sequencer takes a unique approach to sequencing. It can be used in programmed mode
where steps you program are played by like a standard step sequencer. But in the normal mode the steps
are generated from a true analog noise source. Capture some randomness and then loop it. Then edit the
steps if you want or seed part of the sequence with new data as the sequencer is playing. Add to that
selectable scales and rhythms and a dedicated random pulse output, and you will never get bored. Plus the
analog noise source can be used to generate white, blue or pink noise with an adjustable output level.
A great starter system that can be expanded later. Includes an active enclosure and power supply,
four modules and a set of patch cords. Rack ears can be included installed or packaged separately.

Ordering
All systems are hand-assembled and built-to-order in our Toronto workshop.
Systems and modules take approx. 3-4 weeks to build. We assemble and
test the entire system so you should be ready to go as soon as you
receive your system. Worldwide shipping is quoted per order.
Orders require a 50% deposit at the time the order is placed, with
the remainder paid when your order is ready to ship. Canadian residents must
pay HST, which will be added to the second payment.
Products Available to Order
Currently we are taking orders for either System #1 or System #2. Want a
different combination? Let us know and we can help make a system that is perfect
for you. New modules coming soon!

Kilpatrick Audio will warrant all parts of the system against
manufacturing defects for a period of one year from the date of
purchase. If you have a problem with a module, contact us and arrange
to return it to us for repair. After one year, we will offer low cost
service on modules for as long as possible. If you have trouble at any
time please contact us and we will do our best to help you. No
warranty is offered for damage caused by the end user or other
equipment.
Note: This warranty applies to Kilpatrick format
products and takes precedence over our general warranty policies in
the case of any differences.
Kilpatrick Format Usage
The Kilpatrick Format is unique to Kilpatrick Audio, but we want to make information
available to other manufacturers and DIY hackers so they can build high quality modules
that work with the Kilpatrick system.
We are working on a spec which will be available free of charge for both commercial
and non-commercial use. This will be released once we get some systems out there and have time
to document all the little details!
