Analog / Trigger Sequencer

A-155

1. Introduction

Module A-155 (Analog / Trigger Sequencer) is a com-

bined

8-step

analog and trigger sequencer

: it can

simultaneously produce sequences of analog voltages

and trigger and/or gate signals.

Module A-155 works very much like the Clock Sequen-

cer module, A-161, but includes many extra (and

expensive to implement!) functions.

The control section includes switches for Start, Stop,

Step and Reset - which can be operated by push-

button

as well as

digital signals

. Above the top row,

eight LEDs show the progress of the sequence, with

each step’s LED lighting in turn.

The A-155 has two analog rows, each with eight

knobs

, with which to set the control voltage for each

step. The upper row is particularly designed for pitch

control of a VCO, with a

range switch

giving the ability

to set pitches precisely.

The lower row of eight knobs has the ability to accept

an external signal for each step, in which case the

knobs act as attenuators for this voltage.

The variable voltages from the analog rows can either

be output direct, or can go through a sample-and-

hold

section and a

slew limiter (‘glide’).

Using the

S&H and glide control inputs, it’s possible to select

‘hold’ (S&H) or portamento (glide) for whichever step

or steps you want.

Three rows of triggers and one row of gates are

available. For each step, a three-way mini-switch lets

you decide whether one or the other (or neither) of the

two triggers works. Each row has an LED which lights

whenever a trigger or gate is active at any particular

step.
