One could think of a Time Flow Changer as being rather like a clock divider / multiplier in a clock based sequencing system (but without some of the technical limitations.)

There is a simple timing relationship between most LSSP sequencers such as CV Sequencer and Rhythm Sequencer and the V/Bar signal used for their control input. A change in V/Bar voltage of one volt results in the sequencer running through one whole cycle and this corresponds to one bar.

The Time Flow Changer module allows this natural flow rate of a one volt per cycle/bar to be altered so that, for example, a sequence could run 8 times slower than normal by using a 1/8 setting or 5 times faster than normal with a 5/1 setting.
