K1 Mixer Interface
Kilpatrick Format Mixer and MIDI Interface - 1 Space
The K1 Mixer Interface module is a combination of a high quality
five channel audio mixer and MIDI to CV converter. The mixer is
designed for high level signals from other modules and offers both an
AUX send for use with effects, and dual stereo outputs on banana and
mini jacks, as well as a headphone amplifier with dedicated volume
The mixer circuit incorporates high quality low-noise inputs on
banana jacks. Three mono channels and one stereo channel all contain
input level indicators and input level controls. The stereo channel
offers an AUX send level control which sends a post-input level blend
of the left and right channels to the AUX output.
The mono inputs offer level controls, a post-input level AUX send,
as well as a pan control. Channel 5 offers a CV input for panning
instead of a pan control.
The master output contains a stereo level control and a pair of
banana jacks suitable for connection to other modules or
daisy-chaining several mixers. A pair of mini jacks offer line-level
signals that can be output to external audio equipment. Signal level
indicators show the levels at the output jacks and sense the levels
after the MASTER volume control. A ground jack provides access to the
analog ground on the system.
A dedicated heaphone amplifier provides a stereo output on a mini
jack with a dedicated level control. This output can also be used for
powered speakers or stereo recorders that work more conveniently with
stereo mini cables.
MIDI Interface Section
The K1 also contains a small but useful MIDI to CV converter. Built
on the success of the K1600 MIDI Interface, the MIDI to CV converter
on the K1 supports a number of useful MIDI to voltage conversions,
plus a MIDI THRU jack for daisy-chaining. Outputs can be assigned to
note, control change and pitch bend messages. Note playing modes
include single (mono) mode, split keyboard mode, two-voice polyphonic
mode, which is expandable up to 16 voices with additional modules, Arp
Odessey-style duo-phonic mode, and single (mono) mode with velocity
output on the second CV output jack.
Outputs are programmed by pressing the SET button to select the
output mode to program and then sending a MIDI message to the
unit. The MIDI channel, output type and other parameters are stored
automatically in the module and restored at power-on.
