Ardour supports a variety of controllers in the Presonus FaderPort product line. The documentation below is written with FaderPort™ 8 in mind. However, it equally applies to FaderPort 2 and FaderPort 16 as the main difference between these units is the amount of motorized faders. For the documentation on using 1st generation FaderPort devices please refer to this chapter instead.

Connecting the FaderPort 8

The FaderPort 8 (FP8) comes with a USB socket on the back. Connect a suitable USB cable from there to a USB port on your computer. The FP8 will be automatically recognized by your operating system, and will appear in any of the lists of possible MIDI ports in both Ardour and other similar software.

Ardour uses the FaderPort 8 in what PreSonus calls "Studio One" or "native" mode. To use the FaderPort8 with Ardour's FP8 Control Surface, make sure that the device is in "Studio One" mode. (If you would like to change the mode at any point, power on the unit while holding down the two leftmost Select buttons, see the FaderPort 8 manual for further details. Also note that at least firmware version 1.01 is required. NB. "factory default" resets the firmware, see the PreSonus FaderPort8 Owner's manual chapter 9.4.)
While the FaderPort provides a Mackie Control Universal (MCU) mode, which works with Ardour's Mackie Control Surface, MCU does not support various elements available on the FP8 (e.g. colored buttons, and the custom mode scribble strips).

To connect the FP8 to Ardour, open the Preferences dialog, select "Control Surfaces" and enable "PreSonus FaderPort 8". Then open the "Protocol Settings" dialog for the FP8. Which (among other things) allows to select the the MIDI ports corresponding to the FP8.

Once you select the input and output port, Ardour will initialize the FP8 and it will be ready to use. You only need do this once: Once these ports are connected and your session has been saved, the connections will be made automatically in this and other future sessions.

Using the FaderPort 8

The FaderPort's controls can be divided into five groups:

In general the control mapping described in the FaderPort 8 Owner's Manual for Studio One (chapter 2) applies to Ardour as well. There are however subtle differences where the DAWs differ.

Buttons generally act on release (not press), with exception of transport-control (since 6.0pre) and individual exceptions mentioned below.

Transport Buttons

FaderPort8 Transport Buttons

  1. Stop: Stops the transport. Press twice to return to session start.
  2. Loop: Toggles loop playback. A loop-range needs to be defined in the session for looping to be engaged.
  3. Play/Pause: Roll/Stop the transport (note that Ardour has no "pause" mode: Pause is equivalent to stop). During vari-speed playback, pressing "play" resets to 100% forward speed.
  4. Rewind: Rewind, roll backwards. Successive presses or holding the button incrementally changes the speed.
  5. Fast Forward: Roll forward. Successive presses or holding the button accumulate speed. Pressing (Rewind and Fast Forward) simultaneously stops playback and returns the playhead to zero.
  6. Record: Toggles the global record enable setting.

Session Navigation

Session Navigation allows quick navigation and provides access to session-wide controls. Each of the eight buttons alters the function of the push-button encoder and the Prev, Next buttons. With exception of Click the seven modes are exclusive (radio buttons).

FaderPort8 Navigation Buttons
FaderPort8 Navigation Buttons
  1. Channel: The Prev / Next buttons select the previous/next mixer-strip. If no strip is selected, Next selects the first, Prev the last mixer-strip in the session. Pressing the encoder knob moves the most recently selected mixer-strip into view on the FP8. The encoder scrolls the editor-canvas up/down.
  2. Master: The encoder controls the master-bus level. If a session includes a monitor-section, the encoder controls monitor-out by default. Hold the button to control the master-bus level. Press the encoder knob to reset the gain to 0dB. The Prev / Next navigation buttons bank the visible strips on the FP8 by one track left/right.
  3. Zoom: The encoder controls horizontal zoom of the editor. Press the encoder to zoom to fit the session. Prev / Next navigation buttons zoom selected track(s) vertically (or all tracks if none are selected).
  4. Click: Toggle the metronome on/off. While holding the Click button, the encoder modifies the volume of the metronome click (press the encoder while holding Click to reset the metronome level to 0dBFS).
  5. Scroll: The encoder scrolls the timeline (hold Shift for finer steps). Pressing the encoder zooms to fit the session. The Prev / Next navigation buttons bank the visible strips on the FP8 by one track left/right.
  6. Section: The Prev / Next navigation buttons nudge the selected region by the time configured in the nudge-clock. If no region is selected the playhead position is nudged. The encoder always nudges the playhead position.
  7. Bank: Encoder and navigation buttons scroll through mixer-strips in banks of eight. Pressing the encoder moves the most recently selected mixer-strip into view on the FP8.
  8. Marker: The encoder scrolls the timeline (hold Shift for finer steps). The Prev / Next navigation buttons jump to prev/next markers. Press the encoder to drop a new marker.

When combined with Shift, the eight buttons will access custom functions, which can be configured in the Preference Dialog. The buttons will light up if an action has been assigned to a button.

The following tables shows a condensed overview of the session-navigation modes:

Prev / Next Encoder knob Encoder Press
Channel Select prev/next mixer-strip Scroll Editor up/down Bank to show selected strip on FP8
Master Bank visible strips on FP8 by 1 Adjust master/monitor level Reset master/monitor to 0dB
Zoom Vertical zoom (editor track-height) Horizontal timeline zoom (time) Horizontal zoom to session
Scroll Bank visible strips on FP8 by 1 Scroll the timeline (move playhead) Horizontal zoom to session
Section Nudge the selected region Nudge the playhead -
Bank Bank visible strips on FP8 by 8 Bank visible strips on FP8 by 1 Bank to show selected strip on FP8
Marker Move to prev/next marker Scroll the timeline (move playhead) Drop a new marker
Press and hold Click (mode dependent) Adjust metronome Level Reset metronome level to 0dBFS

Shift Button

The two Shift buttons are identical, they're copied to provide convenient access to the modifiers. Pressing and holding the Shift button updates the lights (and colors on RGB buttons) to indicate the modified control.
Pressing and holding the Shift button for one second without pressing any other button enters shift-lock mode. Press Shift again to reset. The Shift button engages directly on press. Activating an action while the button is held will void the shift-lock mode.

Fader Modes

The eight faders on the FP8 can be assigned to various automatable controls present in the current session. The four fader-mode buttons change the behavior of the mixer-strip and scribble strip displays. (Note: with the 1.01 firmware these buttons always act on press.)

FaderPort8 Fader Mode Buttons
FaderPort8 Fader Mode Buttons
  1. Track: In Track-mode, the motorized faders display and control a mixer-strip's signal level. The Pan/Param encoder modifies the azimuth of the panner (hold Shift to control the width, if the track's panner supports it). Mute and Solo affect the respective mixer-strip.
  2. Edit Plugins: When Edit Plug-ins mode is active, the motorized faders will control the parameter settings of a given plugin-insert.
    Press the Edit Plugins button to view all available plugin-inserts on a strip. If no plugins are available, Edit Plugins will not engage and the FP8 automatically switches back to Track-mode.
    Select Plugin Mode: Use the Select buttons under the scribble strip to pick a plugin to edit.
    The Select button color indicates the bypass/enable state of the plugin (red: bypassed, green: enabled). Use Shift + Select to toggle the bypass state.
    Selecting a plugin enters Parameter Edit Mode: The faders and the Select buttons will respectively control the parameters and toggle controls of the selected plugin (once a plugin has been selected, it stays in edit mode regardless of track selection). If there are more than eight parameters, the Pan/Param encoder allows to scroll through available control-parameters (hold Shift to bank by 8).
    If the plugin has any presets, pressing the Pan/Param encoder switches to the plugin-preset display: Plugin preset names are displayed on the scribble-displays, the Select button below each loads the preset. The "Pan/Param" encoder can be used to scroll through presets if there are more than seven (right-most, 8th, slot is reserved to unload/clear a loaded preset, hold Shift to bank by 7). The Select button color is used to indicate the currently loaded preset (if any) and blinks if a parameter has been modified since loading the preset. Loading a preset or pressing the Pan/Param encoder again switches back to the Plugin Parameter Edit Mode.
    In Parameter Edit Mode, the "Open" (Shift + Macro) allows to toggle the Plugin GUI visibility.
    Press the Edit Plugins button again to return to the Select Plugin Mode.
  3. Sends: In Sends mode, each of the faders is mapped to the send-level of aux-sends of the selected track. If there are more than eight sends on a given track, the Pan/Param encoder can scroll through them. Send-mode follow the selection. If there are no sends on a given track, the FP8 automatically switches back to Track-mode.
  4. Pan: When Pan mode is active, the motorized faders will display and control the panner's azimuth. The Pan/Param controls the pan-width of the selected mixer-strip.

Shift + Track toggles timecode display on/off (middle row of the scribble-strip). The timecode format can be configured in the Control Surface Preference Dialog (Timecode, musical-time: bar/beat/tick).

Channel Strip

In Track-mode, pressing the Select button of the most recently selected track (blinking Select button) will reset the fader-gain to unity (0dB). (since Ardour 5.11-207, Mixbus 4.2-66)

While holding the ARM button the Select button lights change to red and the Select buttons controls the record-arm of the given track. Mixer-strips that cannot be record-armed have a dim white light.

Shift + ARM record-arms all tracks in the session.

Mix Management

These buttons allows to select which mixer-strips are spilled on the FP8 channel-strips.

  1. Audio: View Audio Tracks only.
  2. VI: Show tracks with virtual instrument plugins.
  3. Bus: Display only Busses.
  4. VCA: Show VCAs.
  5. All: Display all Tracks, Busses (incl master-bus) and VCAs.

In combination with the Shift modifier ten total filters are available:

Automation Controls

The Automation Controls provide access to the currently selected mixer-strips. The automation enable lights indicates the mode of the most recently selected mixer-strip (blinking selection button). The action affects all selected mixer-strips. The automation controls are currently only available in Track and Pan fader modes where they affect the fader and pan automation modes respectively.

FaderPort8 Automation Buttons

  1. Latch: Currently not available in Ardour.
  2. Trim: Currently not available in Ardour.
  3. Off: Select "Manual" automation mode.
  4. Read: Select "Play" automation mode.
  5. Write: Select "Write" automation mode (note at the end of a write pass, Ardour automatically puts the track into "Touch" mode.
  6. Touch Select "Touch" automation mode.

The Automation Controls also double as session state controls when combined with Shift.

  1. Shift + Latch Save: Save the session. The button lights up red if the session is modified.
  2. Shift + Trim Redo: Redo a previously undone operation. The button lights up green if redo is possible.
  3. Shift + Off Undo: Undo the most recent operation. The button lights up green if undo is possible.

With Shift, the bottom row allows to bind three custom user actions.
