This interface converts MIDI information into 4 control voltages and one gate. It has an external plug-in power supply. It is important that the first control voltage and the gate are always set to MIDI note events, with the pitch bender being converted to the first CV. The remaining CVs can be used to control further parameters of an older synthesiser in the sequencer, e.g. filter modulations. The 3 control voltages can be controlled via MIDI controllers. The interface receives an adjustable MIDI channel, which means that looping the MIDI signal makes sense.

The frequency of the VCO is determined by the position of the range switch and tune controller and the control voltages at the CV inputs. Thus, the VCO provides the possibility of frequency modulation. You can set the footage (octave of the fundamental) with the selector switch. The Tune control is used to fine tune the VCO frequency.

In the pulse wave the pulse width can be adjusted manually or by voltage control or modulated (PWM).

Module A-118 is a noise and random voltage generator. It produces the following signals: white noise, coloured noise, and random voltage. White and coloured noise can be used as audio signals, and also (in conjunction with an S&H module) as a control voltage. The resulting random voltage is mainly used as a control voltage, especially because of its low frequency content.

There are knobs to control the rate of change and amplitude of the random voltage, and two LEDs indicate the state of the voltage.

The module A-132-4 contains four identical voltage-controlled amplifiers (VCA) with exponential normalization. Each VCA has two control voltage inputs (CV1, CV2), a signal input (In), and a signal output (Out). The control voltage inputs CV1.1 and the signal inputs In1 can be bridged with the control voltage input CV2.1 via internal jumpers and with the signal input In2. This circuit is also available between amplifiers 2 and 3 as well as between amplifiers 3 and 4. If this circuit is not desired, then the jumpers must be removed.

In addition, the sum of all four outputs is available (lower left socket with the sum symbol). Therefore, amplifier 4 has only one control voltage input (CV4.1). If necessary, this socket can be bridged as control voltage input 2. Then the sum signal will no longer be available.

For each VCA output a jumper is available, which determines whether the output signal of the corresponding VCA is added to the sum signal. By default, all four jumpers are set (all four VCA output signals are added). By removing one or more of the jumpers, you can select which VCA output is added to the sum. The bridges can also be replaced by switches.
