In 16-step mode we can generate notes with clearly different durations that are separated by silence. A transient generator is patched in self-triggering mode as a clock to drive the sequencer in 16-notes. So the clock is 4 times faster than a quarter beat. When the sequencer moves from step to step, there is no hiatus in the voltage in between: we cannot generate new gates or triggers from the transitions from step to step, unless the voltage returns to zero, or crosses some threshold. The continuity between steps can be used to advantage, however. Here I use the settings on a row of sequencer knobs to gate a simple oscillator signal. This allows us to hear the the effect of the steps on controlling the volume of the signal and creating continuity over more than one step.
There is just one patch cord coming from row D of the sequencer controlling the volume of the oscillator at the VC GAIN input of a VCA, but I have taken it via one half of a Dual Universal Slope Generator. Row D is connected to the IN input of the slope generator, and OUTPUTS is connected to the VC GAIN. The oscillator goes to the IN audio input of the VCA and we are listening to the VCA input. Because the slope generator passes the knob level through, when the knobs of Row D are raised to different amounts, we can still use it to control the volume, but we can use the RISE and FALL knobs of the slope generator to affect the envelope, which becomes trapezoidal in shape. Raising one knob in the row lets us hear the ping, but raising several consecutive knobs to lengthens the duration, in units of a sixteenth beat.
