2a Manual First (knob)

2b First CV (knob) / " First CV (socket)

3a Manual Last (Regler)

3b Last CV (knob) / § Last CV (socket)

This group of elements is responsible for the First and

Last step of the sequence. For both parameters a

manual control (knobs 2a and 3a) and an external

control voltage input (CV inputs " and §) are available.

The CV inputs are equipped with attenuators (knobs 2b

and 3b). The attenuators are used to adjust the level of

the corresponding external CV and consequently the

influence of the CV.

The required control voltage at the sockets " resp. § to

reach all steps is about 0...+5V (with attenuators 2b

resp. 3b at it's maximum and Manual First 2a resp.

Manual Last 3a at it's minimum position).

In the CV Controlled mode the first/last step function

does not work. Rather the controls and the CV input of

the First section (", 2a and 2b) are used in this mode

for the voltage addressed step position of the se-

quence. The controls and CV input of the Last section

have no function in this mode.

Note : If the sequencer seems not to work (i.e. it remains

at a fixed position) please check if the settings of first

and last step are the reason for this behaviour. If the

value of the last step is the same or smaller than the

value of the first step the sequence seems to stop ! But

System A - 100

actually always the same step is addressed due to the

settings of first and last step! If you do not want to use

the first/last step function the manual controls should be

set to minimum (2a Manual First) resp. maximum (3a

Manual Last) and no external CVs should be applied

resp. the attenuators (2b and 3b) should be set to

minimum.

4a Manual Clock (knob)

4b Clock CV (knob) / $ Clock CV (socket)

5a Manual PW (knob)

5b PW CV (knob) / % PW CV (socket)

This group of elements is responsible for the internal

clock generator. Both rate (clock) and gate length resp.

pulsewidth (PW) can be controlled independently. For

both parameters a manual control (knobs 4a and 5a)

and an external control voltage input (CV inputs $ and

%) are available. The CV inputs are equipped with

attenuators (knobs 4b and 5b). The attenuators are

used to adjust the level of the corresponding external CV

and consequently the influence of the CV.

The independent control of rate and pulsewidth leads to

a lot of interesting features. E.g. controlling PW by one

of the A-155 CV outputs allows a different gate length

for each step. But the tempo (resp. clock rate) is the

same for the whole sequence.
