the Voltage Mini-Store
The Voltage Mini-Store is an 8 stage voltage sequencer which draws syncronisation from the Time Buffer, to allow it to run at musically-useful divisions of quarter notes, eighth notes, and sixteenth notes. There is a toggle to select its clock divisor, and this selection does not become active until the sequencer returns to stage one. Because of this behaviour logic, not only the dials but the divisor control itself becomes an exciting performance control in a live or studio situation.
There is also an external shift input which when a 1/4" TS cable is inserted breaks the connection with the internal sync24 bus and puts it under external control, to allow it to be driven from another Time module such as the Trigger Mini-Store's trigger output, or a simple oscillator. The response to external shift clock is well into the audio range, allowing this sequencer to become a sort of digital oscillator. I have not measured its response with laboratory test equipment but I can say that it responds to the full range of a Synthesizers.com Q106 Oscillator with no external voltage applied, and quite nicely.
When connected to a Shift Manager panel, this sequencer becomes a seriously-enabled sequencing element. The Shift Manager allows you to control the sequence length from 1 to 8 stages, provides a Stage One trigger output and input, and allows you to set the sequencer to stop at the end of the sequence instead of cycle to stage one. The length control (like the clock divisor toggle) does not take effect until the sequencer cycles back to stage one. When a trigger is applied to the Stage One input the sequencer will hang at the first stage until the trigger signal is released to 0V, and then advances to the next stage at the next clock divisor or external shift input clock signal. The Stage One output pulses high whenever the sequencer is returned to stage one: under Sync24 control it is a short pulse and under external control the output is high for the duration of the pulse width of the external clock pulse. There is also a toggle switch which allows the sequence to end at whatever stage is selected with the sequence length rotary switch control, and the sequencer will only advance to the first stage when a pulse is applied to the Stage One input jack. This feature allows the Voltage Mini-Store to be used as a tempo-syncronised stepped envelope generator if you wish.
Here's a diagram to explain a bit more visually how it all fits together in an example use scenario:
The Voltage Mini-Store's output swings from 0V to 4.8V approximate. This module only draws power from the 5 volt rail of your system.
