The Non-Mixer is a stand-alone audio mixer, utilizing JACK as an audio subsystem. At the time of writing, the architecture of Non-Mixer is unique. By making the mixer stand-alone, concepts such as busses, sends, and inserts are eliminated, as the same goals can be achieved by simply adding more strips to the mixer.
Each mixer strip has a name and color, each of which may be defined by the user. Names, but not colors, must be unique. In addition, each strip has controls to move it left or right (the arrows) in the display and to remove it entirely (the 'X').

<p>
Strips start out in <i>narrow</i> mode, with the <i>fader</i> view enabled. Click the desired button to toggle the mode or view.
</p>
<p>
The fader view comprises a large gain control and digital peak meter indicator. These are automatically connected to the default gain and meter modules of the strips signal chain.

To see how an audio signal traveling through this strip will be processed, switch to its <i>signal</i> view.

<p>
The signal chain view of a mixer strip provides a way to view and manipulate the signal processing of a mixer strip.
The Module Parameter Editor is used to alter the values of a module's parameters, and, further more, to bind its parameters to controls. A menu button in the upper left-hand corner allows you to select between knob, vertical slider and horizontal slider controls.
Underneath each control is a bind button. Clicking adds a new control to the chain's <i>Controls</i> view and binds it to the parameter in question. For simplicity, only one control at a time may be bound to a given parameter.

<p>
The control voltage concept should be familiar to anyone who has experience with pre-MIDI hardware synthesizers designs. MIDI definitely has its advantages, but MIDI control data is multiplexed and connecting one MIDI control to a parameter usually involves configuring settings on both ends of the connection in order to separate the control data streams.
</p>
<p>
Control Voltages provide a simple 1:1 source to sink relationship and offer much higher resolution, both in time and value, than can be natively expressed through MIDI. The chief advantage of CV in the context of Non-DAW is the ease with which an control sequence can be connected to a mixer module parameter. If you have a MIDI controller that you'd like to use to control parameters of Non-Mixer, consider <i>jm2cv</i>, a JACK MIDI to Control Voltage daemon which was written by Peter Nelson specifically for use with Non-Mixer. jm2cv can be acquired by:
Each mixer strip is presented as a separate JACK "client". This helps to avoid the necessity of internally duplicating JACK's routing logic and, with JACK2, permits the possibility of parallel execution of mixer strip signal chains.
</p>
<p>
The JACK client name of each strip will correspond to the name of the strip.

<tr><td>NOTE:
The JACK API makes implementing this far more difficult and kludgey than it should have to be.
Please petition your local JACK developer to accept jack_client_set_name() into the API.
