This module, that contains two identical voltage controlled crossfader units can be used in combination with controller modules like the Wheels or the Joystick controller to make fades between different sounds ( or even control signals like LFO's )
Each unit has two voltage controlled amplifiers (VCAs) with opposite control behaviour.
In standard (assymetrical) mode, with 0 volts CV added to CV1, input A is fully closed and input B fully opened.
Adding more control voltage to the CV1 input will result a volume increase at input A and a decrease of the volume at input B. In the middle position you will hear a nice mix of the two inputs.
Different settings for the module are available, by switching the internal jumpers you can make the CV inputs ready for bi-directional voltages ( positive and negative ).
By coupling both units you can even control 4 inputs with, for example the A-174 Joystick Module's control voltage, where the centre is the 50% mix and each 'corner' of the joystick is an individual input. A truly amazing and very versatile little module...
There are many ways to house your (eurorack) modular synth, i wrote about the pre-manufactured options from Doepfer earlier, find that post HERE, but of course you can also try to build you own case. There are many ways to make your own A-100/Eurorack case if you start out with just the basic rails and busboard, and you can make it as cheap or expensive as you can.
Doepfer has just released some info on their new modules for NAMM 2017 (19-21 jan.)
Besides some vintage editions of existing modules, the A-135ABC VC Performance mixer modules, the A-110-6Trapezoid Thru Zero Quadrature VCO and a new A-100LC1 case (economically priced small housing with 48 HP width) there was also one other interesting new module announcement:
Module A-150-8 contains eight manually/voltage controlled switches.
Each of the eight switches has a manual control button (Man.), a control voltage input (CV), a common Out / Input (O/I), and two In / Outputs (I/O1, I/O2).
The switches are bi-directional, i.e. they can work in both directions, so can connect one input to either of two outputs, or either of two inputs to one output.
Two LEDs show which in / output is active (ie. which is connected to the common out / input).
In addition the LEDs are used for the programming of the module:
For each unit the operating mode can be selected:
Toggle or Level controlled. In Toggl…
You might have noticed that I havent posted a lot in the last 2 years...
It's been a rough time for me since the sudden loss of two parents within a relatively short time-span and I really needed some time to get myself together... to set things straight, finding myself and selecting priorities... even my regular work suffered from this breakdown.
It took a while to understand it all, and to get a better grip on it, and it's sometimes still not very clear.
I think I have found a way to cope with most of it now... although the slight autism that I have (ADD-like) doesn't make it easy for, especially in crowds with lots of people I don't know...
On my journey I also (re-)discovered the beautiful woman that has always lived inside of me and that i need to accept and cherish... more on that maybe later... I'm not considering changing the name of the blog to PatchPetra.Net 😇 (...yet), but you might spot me somewhere at mod…
