MODULE 2560 - ANALOG / SEQUENTIAL SWITCH

The 2500, 2510, 2520 and 2560 modules perform the basic potentiometer matrix functions of early sequencers. The 2510 is an eight position (3 bit) up/down presetable, cascadable counter; the 2520 is a 4 by 8 potentiometer matrix, and the 2560 is a sequential switch.

The 2560 Sequential Switch allows selection between two, three, or four signal inputs, connecting only one signal at a time to the output. A pulse applied to the Shift input advances the sequence. By default, the sequential switch alternates between stages one and two, ignoring stages three and four until a standard phone plug is connected to Signal Input 3 or 4. When a signal is patched into Input 3, the Sequential Switch alternates between three stages in order at each trigger, and likewise when a signal is connected to Input 4. Separate Trig input and output jacks are provided for each of the four stages, along with buttons for manual switching.

To chain the four rows of the 2520, it was originally necessary to use the 2530 Analog Switch. However, since this module is not a true sequential switch (it has no shift input), it was not possible to step from one row to the next using a clock signal without relying on additional modules such as the 2550 series logic modules. This significantly complicated the musical sequencing workflow.

Mos-Lab therefore decided to replace the 2530 Analog Switch and the 2550 modules with an entirely new module developed specifically for this purpose: the 2560 Sequential Switch. Built entirely with CMOS logic, it eliminates the need for these complex auxiliary modules.
