Doepfer A-111-6

Author Doepfer A-111-6


Module A-111-6 is a complete miniature monophonic synthesizer module that has these features available:

Tune: manual tune control (with an internal jumper the range can be set to ~ +/-1 half an octave or ~ +/-2.5 octaves)
Oct.: range switch -1 / 0 / +1 octave
Mod.: modulation depth (attenuator wired to the Mod. socket)
Dest.: switch that is used to address the modulation to frequency modulation (position FM) or pulsewidth modulation (positon PM), in center positon no modulation
PW: manual pulsewidth control for rectangle waveform, PW can be also modulated by the Mod. input as mentioned above
Wave: waveform switch (sawtooth / off / triangle), the sum of the waveform chosen by this switch and the rectangle is fed into the VCF (to turn the rectangle off the PW control has to be set fully CCW or fully CW)
1V/Oct. (socket): external CV input for VCO frequency (1V/octave)
access to internal bus CV (via jumper, optional, please remove the bus jumper if this feature is not used to avoid unwanted frequency modulation as then the unused CV line of the bus works as a kind of antenna)
triangle core VCO, frequency range about 32Hz ... 8kHz (??? still to be specified)
Balance unit

The balance unit is made of two VCAs which are controlled by the sum of manual Balance control and the balance CV input in the opposite direction.
The audio input of VCA1 is hard-wired to the VCO output, audio input 2 is connected to the socket Ext.In.
The output of the balance unit is used as audio input for the VCF
Bal.: manual balance control, fully CCW the internal VCO is used, fully CW the external signal (Ext.In) is used, at center position both signals have about the same level
CV Bal.: CV input for balance (range about 0...+5V)
Ext. In: external audio input for VCA2, about 5 Vpp level required for similar loudness as the internal VCO
this socket is normalled to the internal VCO suboctave f/2 signal (rectangle with half the frequency), if no external signal is applied the suboctave signal is used as the second signal for the balance unit

24 dB low pass
Frq.: manual frequency control
FM1: frequency modulation depth (attenuator wired to the VCF FM1 socket, the socket is normalled to the internal Envelope signal and then FM1 controls the modulation depth of the internal envelope applied to the filter)
FM2 (socket) : second CV input for VCF without attenuator (about 1V/octave), can be used e.g. for VCF tracking by connecting the same CV which is used also for the VCO frequency
Res.: manual resonance control (up to self oscillation)
if the VCO is turned off (waveform switch = center position, pulsewidth control = fully CCW or CW) and the VCF resonance is set to maximum the module can be used as a sine oscillator, the tracking at socket VCF FM2 is about 1V/octave (not as precise as the VCO but much better than most other filters)
~ 11 octaves frequency range (~ 10 Hz ... 20kHz)

Gain: manual amplitude control (initial gain), can be used to open the VCA without envelope signal
VCA (switch): used to switch between gate and envelope as control signal for the VCA, in center position the VCA is not controlled by envelope or gate
note: when gate is used the VCA is controlled directly by the gate signal (i.e. hard on/off), this may lead to clicking noise under certan conditions (especially with low VCO/VCF frequencies)
special control scale: exponential scale in the range from about -20dB to -80/90dB, linear scale from about -20dB to 0dB
Remark: this special control scale results in a loudness behaviour that is a bit different from pure linear or exponential VCAs
Out: audio output of the module (= VCA output)

Gate (socket): Gate input (min. +5V), can be normalled to the bus gate signal by means of a jumper
Att: manual control for Attack
D/R: manual control for Decay/Release
Env. (switch): used to switch between A/D, ADSR and A/R mode of the envelope generator, in center position (ADSR) the sustain level is fixed to about 50%
Envelope (socket): envelope output (about +10V)
CVT (socket): CV input for time control, by means of two internal jumpers one can select which time parameters are controlled by the CVT input (e.g. A only or D/R only or A/D/R) and in which direction (i.e. if an increasing CVT shortens or stretches the time parameter in question)
Envelope LED display
Attack time range: ~ 1ms ... 5 sec (can be extended by using the CVT input)
Decay/Release time range: ~ 1ms ... 15 sec (can be extended by using the CVT input)
The distances between the controls and sockets are smaller as for the standard A-100 modules and rubberized small-sized knobs are used. In return the front panel has 10 HP width only for a complete synthesizer voice. The module is primarily planned for applications where only limited space is available. The module can be treated as a slimmed version of the A-111-5 synthesizer voice.

Didn't see a topic for this yet. €180 at Thomann. It seems like a bargain. 3340 VCO?
It was mentioned in this post about the slim line series:
sutekina bipu-on
Oh wait, is this out now? I noticed the release date was TBA for a while. Is in in stock at Thomann? I see it as coming soon at Schneidersladen...
Says due in 2 - 5 days!
180 euro is a steal!
Look forward to hearing some demos

Where? hyper

On Schneidersladen it says "soon".
Thomann says 6-7 weeks...
Mmm... theyve chanhed the date. Or i imagined it....

Perhaps they were promised a few which now and people "pre-ordered" them all?
Can't be... on the other hand this is the most compact most complete synth voice as of yet.
In vintage black style also, apparently:
On the Doepfer website this module is said to be available mid/end october ... and it states even 2019 hihi
ANd only 60ma! How DO they do it!? we're not worthy we're not worthy nanners nanners
Anyone have this now? Any reviews?
If the core is the same as the precision VCO I'm definitely scooping this up for my KB37. I don't usually like hyperdense modules but the features and normaling here are fantastic.

I understand this uses the CEM3394 which is a complete synth on a chip (and the functionality suggests that is the case). The precision VCO is a CEM3340.
