DOEPFER A-190-5 Preliminary Manual

Preliminary Manual (Dec.18, 2018)
Module A-190-5 is a four voice Midi/USB to CV/Gate interface.
For each voice a pitch control voltage (CVNote, 1V/octave standard to control VCOs), a gate output (to
control envelope generators) and two additional control voltages (CV2, CV3) are available. The two
additional CV outputs can be controlled by Midi velocity(CV2), (CV3) volume, modulation, all other free
assignable Midi controllers , after touch.
The mode is selected by means of momentary switches and is shown in the LC display.
Certain parameters of each mode can be edited (e.g. the midi channel(s), the midi reference note for
0V CV, assigned controllers for CV3).
The parameter values (e.g. midi channels) are shown in the display and can be modified by means of
the momentary switches.
In Play mode the LEDs of the first four switches display the gate states.
a. Display : 2x16 char.LCD display shows names of modes, functions and parameter names as
well as parameter values.
b. Return : Opens up a sub function resp. takes you to the next lower level of the menue structure
(down). It also has to be pressed to confirm some functions.
c. Escape : Takes you back to the next higher level of the menue structure (up). It may also be
used to cancel certain functions.
d. < / - : Takes you back to the previous function / parameter on the current menue level
(backwards). It also decreases a parameter value by one step at a time. When pressed down
continously , the value change will be accelerated.
e. > / - : Takes you to the next function / parameter on the current menue level (forward). It
also increases a parameter value by one step at a time. When pressed down
continously the value change will be accelerated.
f. Shift1 Intended for future extensions
g. Shift 2 Intended for future extensions
In- / Outputs:
1. USB port: Input for MIDI data. (USB Class Compliant, no need for a custom driver )
2. MIDI IN : Input for MIDI data (DIN socket)
3. MIDI THRU : Output to loopthrough for most of incomming MIDI data events to another
Matrix of Outputs 4x4
1,2,3,4 on A,B,C,D = 16
In each column 1-4 is one of 4 'Voices' / Voices, each with:
A. Gate : GATE signal outputs
B. CV Note : Outputs for control usually used for controlling VCO pitch.
C. CV 2 :
Output for control voltage Velocity.
May be used to control additional parameters just like e.g. VCF cutoff or VCA level
