Intellijel Shifty is a sequencer module for modular synthesizers in Eurorack format. It is a combination of four sample and hold stages, sequential gate and sequencer controller. The primary use of Shifty is to route each new note in a monophonic sequence to one of up to four synth voices according to a certain pattern. This way pseudo-polyphonic sequences can be created: one voice is triggered and sounds out while the next voice is already triggered in the sequence. Another term for this is hocketing. But Shifty also offers many possibilities as a shift register.
