Module A-119 (External Input / Envelope Follower) is designed to allow external audio signals to be integrated into the System A-100. It comprises a pre-amp, envelope follower, and comparator. The pre-amp has two inputs: an unbalanced input for line level signals, with a gain factor of from 0 to 20, and a balanced input with a gain factor of from 0 to 500, for insertion of low level signals, for instance from a microphone or electric guitar. The Envelope Follower reads the signal level of the input, and puts out a proportional voltage as an envelope at its own output. The comparator generates a gate signal whenever the input goes above an adjustable trigger threshold. Three LEDs help you keep track of overload, the envelope, and the gate signal.

Module A-138d can be used in two different ways:

• as a crossfader module within the A-100
• as an insert module for external effect units (e.g. guitar stomp boxes) with dry/wet control

If the module is used as a crossfader within the A-100 the two audio signals are connected to the sockets In 1 and In 2. The position of the CF (Crossfade) control defines the relation between the levels of the signals In 1 and In 2 that appear at the Mix Output. In the leftmost position of CF only In 1 appears at the output, in the rightmost position only In 2. In the center position both inputs appear with the same level at the Mix Output. Each input is equipped with two sockets (miniature multiples) so that the input signals can be forwarded to other modules too. Even the Mix Output has two sockets available. The mute switch can be used to mute In 1 or In 2 independent of the position of the crossfade control. In the center position it has no function. The controls Atten. and Amp. and the 1/4" sockets FX Send and FX Return are not used in this application. 

If the module is used as an effect send/return module with dry/wet control the A-100 signal that has to be processed by the external effect unit is connected to In 1. The signal can be attenuated by control Atten. before it is output to the 1/4" socket FX Send. The attenuator has been added because some effect units without input level control (especially guitar stomp boxes) will distort with A-100 levels (~ 1 Vss or more). The attenuator can be used to reduce the signal level so that no distortion occurs. Atten. is adjusted so that the external effect unit does not distort. The output of the external effect unit is connected to the 1/4" socket FX Return. This socket is followed by an amplifier and the control Amp. is used to amplify the signal to obtain again A-100 audio level (~ 1Vss or more). Amp is adjusted so that the loudness of both signals (i.e. original = dry = In 1 and the effect return signal = wet = In 2) have nearly the same loudness. The amplification range of the FX return amplifier is 1 to 50 (or  0 to 33dB). The output of the amplifier is normalled to the upper socket of Input 2. In this application no plug is inserted into the upper In 2 socket. The lower In 2 socket can be used to obtain the effect return signal before it is processed by the crossfade unit of the A-138d. The CF control of the A-138d works now as a dry/wet control for the external effect. In the leftmost position of CF only the original signal (i.e. not processed) appears at the Mix Output, in the rightmost position only the effect signal. In the center position the original and the processed signal appear with the same level at the Mix Output. The mute switch can be used to mute the original or the effect signal independent of the position of the crossfade control. In the center position it has no function.

Module A-190-8 is a Midi/USB to Sync interface.

The main application of the module is the control of clocked A-100 modules like sequencers (A-155), sequencer controllers (A-154), trigger divider (A-160 or A-163), trigger sequencer (A-161) and similar units. It may be used also to reset or sync LFOs (e.g. A-145, A-147, A-143-4) or to trigger envelope generators (A-140, A-141-2, A-143-1, A-143-2) with a fixed clock rate.

Subway is a scanning crossfader with 8 inputs and 1 output.

The eight inputs can be used for control voltages as well as audio signals. A potentiometer or CV can be used to mix between the individual sources. Each of the inputs also has a manual on/off switch.

Application examples

• complex modulations
• Waveform selector for oscillators or noise
• Morphing waveforms from wavetables
• Switching between different envelopes

Controls:

• Scan knob - master control over which input goes to the output. The knob is shifted when a CV is applied to the scan CV input.
• Enable switch - Controls which input is active. When the LED is off, the input is removed from the output selection. A dim LED means the input is active but not yet selected. Bright LED means that the input is currently being sent to the output.
• Curves: Subway has three different curves if you hold down keys 1-3 when switching on and then release them. Button 1 sets a linear curve, button 2 sets an exponential curve and button 3 sets a steady curve.
