5. User examples

Module A-135 enables voltage controlled mixing of
up to 4 audio sources
with 4 different control volta-
ges.

The control voltages can be generated by any voltage
source or even by audio sources for special effects
(similar to ring modulator or FM sound). Here are
some examples of possible control voltage sources:

• LFOs (A-145, A-146, A-147)
• ADSRs (A-140, A-141, A-142, A-170)
• Random (A-118, A-148)
• Shepard-Generator (A-191)
• external audio signals in combination with an enve-

lope follower (A-119)

• Analog sequencer (A-155, MAQ16/3)
• Theremins (A-178)
• Light controls (A-179)
• Foot controls (A-177)
It is also possible to use MIDI-controlled voltages in
combination with a MIDI-CV-Interface (A-190, A-191,
MCV4, MCV24):

• Pitch CV
• After touch
• Pitch bend
• Modulation
• Volume
• any MIDI Controller

For example, the combination of A-135 and A-191 can
create a simple MIDI-controlled mixer.

One special application is using the Morphing Con-
troller A-144
to generate the control voltages for the
A-135. This enables cross-fading (morphing) of 4 au-
dio sources with only one controlling voltage. This
single controlling voltage defines the fading or mor-
phing position. For details refer to the A-144 user’s
guide.
