The Progression module works in conjunction with the Adroit Synthesis Song Control Sequencer and other modules to sequence chords into a chord progression.

Chord progressions are programmed by patching chords into the input sockets.

The CHORD OUT socket transmits the current chord in the sequence.

The BASS OUT socket transmits the pitch voltage of the lowest note in the current chord.

Chord signals are provided by modules in the Adroit Chord and Scales Bundle such as the Chord or Diatonic Triads modules.

Chords need only be fed to inputs where a chord change occurs, so if say all the first four steps use the same chord then you only need to plug a chord into the first socket.

The Progression module can handle a progression of up to 16 steps. The length of time this represents depends on how quickly you want chord changes to occur.

Use the CHORDS/BAR buttons to select how quickly chords can change, from once per bar to four times per bar.

When CHORDS/BAR is set to 1 the module can sequence a progression of up to 16 bars in length.

When CHORDS/BAR is set to 2 the module can sequence a progression of up to 8 bars in length.

When CHORDS/BAR is set to 3 or 4 the module can sequence a progression of up to 4 bars in length.

If you are producing electronic dance music then chords don’t typically change very quickly so a setting of 1 will suffice.

Like all Adroit Synthesis sequencers, the Progression module uses the V/Bar standard where time is represented by a voltage rather than being dependent on clock signals.

The V/BAR IN socket is fed with a V/Bar voltage controlled time signal that controls which step in the progression is selected and fed to the CHORD OUT socket.

If the chord progression is the same length as a section of the song (or you want the progression to loop) then this module can be directly connected to the V/Bar output of a Song Part module.

If you want to program a chord progression with more steps than available in a single module then multiple modules can be chained together using Song Part or Time Splitter modules and the MERGE socket.
