Analogue Systems RS-200 sequencer

A true analog step sequencer with three rows of eight steps for generating control voltages and trigger signals. The RDS200 impresses with an internal, voltage controllable clock generator, portamento, reset start/stop functions and a voltage influenced skip feature.

Each of the three rows A, B and C has eight potentiometers for setting the voltage for each step plus a range potentiometer that sets the maximum possible outüut voltage between 1 and 10V (read: 1-10 octaves). Row C has in addition a slew parameter, smoothing the abrupt voltage changes between steps - a classic portamento up to 1 second length.

The section below has a number of rocker switches for generating triggers and events:

- The red switches generate a trigger for each step: in upper switch position a trigger will be output for the according step at the "Trig Out 1" socket. Middle position = off. Bottom position = trigger at "Trig Out 2". The output "Trig Out 3" generates triggers at each step, no matter which position the switches are.

- The eight white switches activate per step a certain global function:

• Reset: sets the sequencer back to step 1, this is used to shorten the sequence.
• Run: step will be played normally
• Skip: this step will be skipped and the sequencer proceeds directly from the previous step to the next one. The skip function will change though when a CV is applied to the Skip In at the right hand section (see below)

A control voltage ranging from +1V to +10V at the Skip input will modify the behaviour of a skipped step. Instead of being skipped, the CV will be held as long as it is removed or if it falls below 1V.

A reset button and a reset socket are used for external resetting of the sequencer. Another button and a trigger input start and stop the sequencer. After finishing each sequence cycle a trigger will be generated at the "End Pulse Out" socket.

The RS200 features an integrated, voltage controllable clock generator; it´s clock is available at a socket and can be used for synchronising other devices. Alternatively you an apply an external clock. A switch selects te clock source: upper position = external clock, bottom position = internal clock, middle position = proceed to the next step by hitting the STEP button.
