Master Filter - Controls filter frequency of the entire mix, like an analog synth. It is always active.

Macro Controls 1 - 8 - Eight multi-functional rotary encoders. The panel legends describe in general terms each encoder's function as applied to the synth tracks for the default Patches.

• The movement of Macro controls in performance mode may be recorded and replayed.

Master Volume - controls the overall level of Circuit Tracks' audio outputs.

View - Each View provides information and control of a particular aspect of a particular track, pattern or sound selection ,timing adjustments, etc.

• Note also that several buttons have an additional ‘Shift’ function, indicated on (or above) the button by a legend in a smaller font.

Many buttons (including Record) have both a momentary (long press) and a latching (short press) mode.

• A long press will temporarily display that button's view, but only while the button is held down. When released the view will revert to whatever it was before the button was pressed.
• A short press on a button will switch the grid view to that programmed into the button.
  • The Record button is a special case as it does not invoke an alternative grid display, but its momentary action allows rapid punch-in and punch-out of Record Mode.

Track Buttons: Synth 1 and 2/MIDI 1 and 2/Drum 1 to 4 - These eight buttons select different grid Views. Their operation varies slightly depending on other user actions.

Step Buttons: Note, Velocity, Gate and Probability - these switch the grid to further Views, and allow parameters of each step of the pattern to be individually entered, deleted, or modified, for the currently selected track.

• Note that Probability is the Shift function of the Pattern Settings button.

Pattern Settings - switches the grid to a View that allows adjustment of pattern length, playback rate and direction for the currently selected track.

Step Page (1-16/17-32) - elects whether the Pattern for the currently selected track is initially 16 or 32 steps in length. When a 32-step Pattern is selected, the colour of the button legend changes when the sequence is running to indicate which “half” of the sequence the grid is currently displaying.

• You can choose to have a 16 or 32-step Pattern on any track.

Scales - Opens Scales View: allows the selection of one of sixteen different music scales for the synth keyboard, and also lets you transpose the synth keyboard to a higher or lower key.

Patterns - Opens Patterns View:  lets you store multiple patterns for each synth, MIDI and drum track, and to join them together to make a pattern Chain.

Mixer - Enables the Mixer View, where you can mute or adjust the level of each synth, drum and audio input making up the sequence, and also to pan each track across the stereo image.

FX - Opens the FX View; lets you add reverb and delay effects to each synth, drum and audio input individually.

Record and Play - Start and stop the sequence, and enter record mode.

• In Play mode anything you play on the grid will be heard
• In Record mode, anything you play will be heard and also added to the sequence.

Preset - Opens the Preset View for the currently selected track. Each synth track can use any of 128 patches, each MIDI track can use any of the eight MIDI templates, and each drum track can use any of the 64 percussion samples.

• The synth and drum Presets are arranged in pages of 32.

^ and v - these two buttons have different actions (and colours) depending on the currently selected View. In Note View they let you shift the pitch of the synth pads or the MIDI tracks up by one of five octaves, or down by one to six octaves when entering notes: the pitch range of each track is adjustable independently.

• In some views, they allow the selection of a second page. (i.e. Pattern View lets you select from eight Patterns per track, although only four are displayed at a time.

Temp and Swing - Tempo lets you set the BPM (tempo) of the sequence, using Macro control 1; Swing alters the timing between steps to change the ‘feel’ of a pattern, using Macro 2 for adjustment.

• In this mode, Macro 5 adjusts the level of Click track.

Clear - allows deletion of individual sequence steps, stored Macro control movements, Patterns or Projects.

Duplicate - operates like a copy-and-paste function for patterns and individual steps.

Save and Projects - lets you save your current Project and open a previously-saved one.

Shift - several of the buttons have a “second function”, which is accessed by holding down the Shift button while pressing the button in question.
