The fader is used to bring an audio signal in or out, or can alternatively also be used as CV.
Based on a standard exponential function, the slope parameter can be used to adjust the characteristics of the fade.
The fades can be triggered with an LED button or via trigger-in.
Use the Fader-16 for big patches or save some CPU cycles with the 8 port version.
When the inputs of a channel are connected the signal is used for the fades.
If only one input is connected only the corresponding output will be active.
Without a signal on the inputs the output will be between 0V and 10V.
Press the buttons or provide a trigger pulse to toggle fades.
The fade in and fade out time can be set in seconds using the knobs.
As indicated at the top of the column the slope parameter defines how the fade curve will "feel". Values >1 will feel more natural, whereas values <1 will give you a fade-in that can punch though existing sounds in the frequency range earlier. A value of 0 would be linear.

The htAdder is an implementation of the Doepfler A-185-2 Precision CV Adder, plus the additional feature of controlling the mode switches with a CV input.
There are 5 CV inputs which can, depending on the mode (-/0/+) be subtracted, bypassed or added on top of each other. The resulting sequence will be sent to the output.
If there is no input present, but a mode of either + or - is selected the switch becomes an octave switch, since the voltage for each channel (except ch.1) is +/-1V by default.
The first input port has, other than the other 4, a default voltage of 1V * the knob value, that means a total of 0-1V when there is no input connected.
If a signal is connected to the first input a fraction of 1V (* knob value) will be added or subtracted to / from it. This can be used as a fine tune.
All other inputs default to a voltage of 1V or the CV that is coming in through the input.
The fine tune knob does not work on them.
The output is the total of all inputs that have selected a mode other than 0 (bypass).
There is also an inverted output port available below the original output.
A mode switch can have 3 states:
0 (bypass) - Does not add or subtract the input CV or default voltage
+ (add) - Adds the input CV or the default voltage to the total CV
- (sub) - Subtracts the input CV or the default voltage from the total CV
A mode switch can be itself controlled by CV as follows:
0V - select bypass
>0V - select add mode
<0V - select sub mode
