Dual Sequential Switch (DSS)

Dual Sequential Switch for Buchla format... intended as a companion for the 245/246 sequencers or the many other "quad" modules in the Buchla world such as the 281 and 292.

The main I/O is bidirectional, meaning that the module works as a 4:1 multiplexer or a 1:4 demultiplexer.

CV control over Length and Mode is provided (scaled to a 0-10V range, although negative voltages are also supported if you want to subtract instead of add to a value). The "L.BND" output is for Length Boundary... a pulse is generated whenever the length changes (whether manually or via external CV).

The module can be built with your choice of bananas or Tinijax on either or both sections (not just bananas as shown in the illustration above). The main I/O circuitry is designed to handle both AC and DC signals, it's just a question of installing one type of jacks or the other.
