Doepfer in Black... Vintage Style

Exciting news from Doepfer for this upcoming NAMM2016.

First this:
Finally they decided to release modules featuring black frontpanels with white print and vintage style knobs.
The result is truly stunning... i would love to change all my silver frontpanels rightaway :)
It will also look great with their latest series of Special Edition modules.

Imagine this with their new colored knobs too... i'm very excited for this :)

So far for these modules vintage versions are planned:
A-110-1 Standard VCO, ƒA-110-2 Basic VCO, A-114 Ring Modulator, ƒA-118 Noise/Random, A-120 24dB Transistor Ladder Lowpass Filter, A-132-3 Dual Linear/Exponential VCA, A-138 Mixer, A-140 ADSR, A-147-2 VCDLFO, A-148 S&H/T&H, A-180-2 2x4 Multiple and the A-190-3 USB/MIDI-to-CV/Gate Interface.
If there are sufficient inquiries they will offer the black panels and vintage style knobs as spare parts.
There are also plans to offer more modules with black panels (e.g. the sequencer series A-154/A-155/A-156).

Each module (old and new ones) will be available in any case in the standard version (i.e. silver-grey aluminium with grey knobs).
But they will offer some modules also in the vintage edition (black front panels with black glossy vintage style knob with metal disc
at the top) or other Special Editions (like the black/yellow A-124 Wasp, the blue/white A-110-4 Thru Zero Quadrature VCO or the (upcoming) cream/black A-106-5). So there is no need to dispute. Simply order the version you prefer.

After NAMM Doepfer will decide how they will proceed...
 
Update 22/02/2016:

Presumably in April 2016 these modules will follow as vintage versions:
A-112 Sampler, A-138b Mixer, A-154 Seq, A-155 Seq, A-156 Dual Quantizer, A-160-5, A-170 Slew Limiter, A-188-1 BBD and A-199 Spring Reverb.


Likewise the Low Cost Cases A-100LC3, A-100LC6, A-100LC9 and A-100LCB will be available in black coated versions from April 2016. 
The above picture shows the vintage modules mounted into a black A-100LC3. 
More information, prices, picture, release dates will be available about middle of March 2016. 
The surcharges will be in the range Euro 45 (A-100LC3) to Euro 80 (A-100LC9).

Doepfer A-147-2 Voltage Controlled Delayed LFO Announced

Doepfer recently announced the A-147-2, the successor of the VCLFO A-147.
This module but offers more features than the predecessor and is made of the following sub-units:

VCLFO: voltage controlled low frequency oscillator
VCA: voltage controlled amplifier, switchable to voltage controlled polarizer
VC delay unit: voltage controlled linear attack envelope (only one parameter: attack) for delayed LFO operation in combination with the VCA (e.g. delayed vibrato/tremolo)

"LFO: The voltage controlled LFO has the waveforms Triangle, Sine, Sawtooth and Rectangle available and features a Reset/Sync input. Triangle/Sine and Rectangle are displayed by means of dual-color LEDs (probably red/green), Sawtooth has a unicolor LED available (probably blue). 
The output levels are about -4V...+4V for Triangle, Sine and Rectangle. 
The Sawtooth level is about 0...+8V.
The CV control can be switched to attenuator or polarizer ("CV Mode" switch). 
In polarizer mode the CV inputs affects the frequency in the reverse manner when the CV control is left from the center position. In the center position CV has no effect and right from the center the control works like a normal attenuator. 
The frequency range (without external CV) is from about 0,005 Hz (i.e. about 3 minutes per periode) to 200 Hz. In addition a ultra-low mode can be activated by means of an internal jumper. 
When the ultra-low jumper is set a fixed voltage is connected to the switching contact of the "LFO CV" socket. In polarizer mode of the CV control that way extremely low frequencies (up to one hour period and more) are possible.

VCA: This is a linear VCA that can be switched to "normal" VCA (i.e. kind of a voltage controlled attenuator) or voltage controlled polarizer ("VCA Mode" switch). 
In the "normal" VCA mode amplification +1 is achieved with about +5V control voltage. 
In polarizer mode the amplification ranges from about -0.5 (i.e. inverted signal with about 50% level) with 0V CV to +0.5 (i.e. non-inverted signal with about 50% level) with +5V CV. With about +2.5V CV the signal is suppressed.
Details about the functioning of a voltage controlled polarizer can be found in the description of the module A-133. In this mode the VCA can be treated also a DC coupled ring modulator (similar to A-114).
The VCA of the A-147-2 has three sockets available: "In" (signal input), "Out" (signal output) and "CV" (control voltage input).
The Triangle Output of the LFO is normalled to the VCA signal input by means of the switching contact of the "VCA In" socket. If another LFO waveform (or any other signal) should be processed by the VCA the corresponding signal has to be patched to the "VCA In" socket. 
The VCA can be used also independently from the LFO and the Delay CV. 
In this case the VCA sockets In, Out and CV have to be patched accordingly. The VCA can be used also as waveshaper for the LFO signals (e.g. by patching VCA In and VCA CV to different LFO signals, if necessary via attenuator A-183-1 or offset generator/attenuator A-183-2).

A-147-2 block diagram
Attack/Delay: The third sub-unit of the module is a simple, voltage controlled envelope generator that has only the parameter "Delay" (or Attack) available. 
This unit generates a linear increasing voltage that starts from 0V after each Delay Reset until it reaches about +5V.
Then the voltage remains at +5V until the next Delay Reset occurs. 
The inclination or gradient is controlled by the manual Delay control and the Delay control voltage ("Delay CV" input). 
The waveform is linear, the control scale is exponential. The output voltage is displayed by a unicolor LED (probably orange) and available at the "Delay Out" socket.
The manual Delay control ranges - without external "Delay CV" - from about 5ms (fully CW) up to 2 minutes (fully CCW). By means of an external voltage applied to the "Delay CV" socket this range can be extended. A rising CV shortens the delay time (behaviour like a VCO) !
The Delay output voltage ranges from about 0V to +5V. The rising edge of the gate, clock or trigger signal applied to the "Delay Reset" sockets resets the Delay output voltage to 0 V.
"Delay Out" is normalled to the VCA CV input by means of the switching contact of the "VCA CV" socket and consequently controls the Triangle level provided that no other patch is made. 
A typical example is the usage of a Gate signal (e.g. from a USB/Midi-to-CV/Gate interface) as Delay Reset. 
That way a delayed vibrato or tremolo can be realized if the VCA output is patched to the frequency CV input of a VCO (or VCF), or the CV input of a VCA.
But the Delay sub-unit can be used also independently from the LFO and VCA, e.g. as a voltage controlled waveshaper or for other applications where a linear increasing signal with voltage controlled steepness is required."

The module is planned for early 2015, price ~ Euro 120.00, price and release date are still without obligation !
