The latest version of the Serge Analogue Programmer/Sequencer, the ES28 has 8 stages each with 4 programmable outputs. The ES28 also adds a new level of user flexibility by utilising the ES34 TouchPad as a remote (requires an umbilical cable) touch controller.
The ES34 is available as a separate item although the ES28 can be operated without the ES34.
