The Song Part module works in conjunction with the Song Control module and any number of additional Song Part modules to form a high-level Song Control Sequencer to manage the overall structure of a song.
The steps of the Song Control Sequencer, rather than being individual notes, are the sections of a song. For instance Intro, Verse 1, Chorus 1, Verse 2, Chorus 2, Bridge, Chorus 3, Outro.
Each Song Part module represents one section of a song and any number of these modules can be linked together in series using the LINK IN and LINK OUT sockets to form songs of any length.
The SOLO button enables a single part of the song to be isolated while you work on perfecting it (there’s no need to fiddle with looping controls). A LED on the Song Control module illuminates to remind you that a part is soloed.
The duration of the part is set by the NUMBER OF BARS control. Valid values are anything from 1 to 64 bars.
In a simple setup a Song Part module’s V/Bar output would be directly connected to the V/Bar input of a sequencer and the sequencer would loop for as many bars as is set by the NUMBER OF BARS control.
But an intermediate layer of sequencing control can be inserted using Time Splitting modules to enable more elaborate multi-bar sequencing.
A variety of Time Splitting modules is provided to enable the construction of long sequence chains or pattern based sequences such as ABAC or AAAB that take advantage of repeating motifs.
Also note that different Song Part modules can drive the same sequencers so that for instance a chorus need not be constructed multiple times.
The IS ACTIVE socket provides a gate signal that is high when the part is playing. This can be used to control any aspect of your setup, perhaps controlling the application of an effect to just one part or to engage different elements of the sequencing system – for instance to bring in an extra instrument to differentiate one verse from another.
The FADE IN and FADE OUT sockets provide signals that can be used to control VCAs – making it really easy to create fade in, fade out and cross-fade effects. They can of course also be used for other purposes such as creating dramatic filter or oscillator sweeps.
Both sockets are outputs. The graphical symbols are used to avoid having clumsy and confusing text labels like FADE IN OUT and FADE OUT OUT and also to give a good visual hint of the functionality.
The FADE IN signal is 0 volts from the beginning of the song until the part becomes active and then smoothly increases to 5 volts over the duration of the part and then stays at 5 volts until the end of the song.
The FADE IN signal stays at 5 volts when a song ends. It resets to 0 volts when a song is restarted.
The FADE OUT signal is 5 volts from the beginning of the song until the part becomes active and then smoothly decreases to 0 volts over the duration of the part and then stays at 0 volts until the end of the song.
The FADE OUT signal stays at O volts when a song ends. It resets to 5 volts when a song is restarted.
