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. This can be done directly with cables or by using Virtual Modular’s bus system.
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.
Chords need only be fed to inputs where a chord change occurs, so if say the first four steps all use the same chord then you only need to plug a chord into the first socket and then a new chord into the fifth 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.
If you are producing high tempo electronic dance music then chords don’t typically change more often than once per bar but the Progression module offers enough flexibility to support all manner of genres.
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.
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.
