3.4 Internal Patching
Taiga Keyboard utilizes internal patching to create a three oscillator synth voice that does not require patch cables to play.
The default internal patching is meant to create the expected or most commonly used signal path for each function. The
default patch moves the audio and control signals from left to right. The [Control] module manages Midi to CV conversion,
arpeggiator, and digital modulation tools setting the pitch of the oscillator and triggering the envelopes and / or dynamics
controller. The output of [Oscillator 1], [Oscillator 2], [Oscillator 3] is sent to channels 1, 2, 3 of the [Mixer]. The mixer outputs
to the [Pgh Filter]. The output of the lter is sent into the [Dynamics] controller to manage both amplitude and harmonics.
The signal then passes through the [Echos] analog delay before being sent to the main and headphone [Output].
Each default patch will be highlighted and explained in the corresponding individual module section of the manual.
To modify the internal patch or to create something completely new, all of the internal routing can be bypassed using
patch cables. This allows total patching freedom without the constrains of a xed voice architecture. Plugging a patch
cable into an internally patched input jack will override any internal patching. Most internal connections are made using
switched jacks. A switched jack allows the internal signal path to be disabled when a patch cable is inserted. A simple
example would be the [FM Input Jack] of oscillators. Internally, the lfo outputs are wired to the switched jack [FM Input Jack]
of each oscillator. When a patch cable is plugged into the [FM Input Jack] of one of the oscillators, that patch cable breaks
the connection to the lfo output to that oscillator and replaces it with the signal from the inserted patch cable.

The diagram below shows the pre-patched audio and CV signals. Each signal is patched with a unique color for clarity.
