Analogue Modular System A-100
The A-155 is a dual 8 step analogue sequencer with 4 trigger/gate tracks in 2 rows.
The sequencer has 8 CV controls with octave range switching (1V/2V/4V), adjustable glide time (portamento slew limiter), S&H control.
There are pre and post glide/S&H outputs.
There are 8 external inputs for the 8 steps for control signals or audio, the controls of the lower row then act as attenuators.
The trigger rows have 3 position toggle switches which can be used to send a trigger/gate to the track above, below or none.
The 3 trigger rows supply a short pulse for each step set, the pulse width corresponds to the pulse width of the clock/step input signal, whilst the fourth row is for gate.
The A-154 module offers more functionality and expandability for the A-155.
