Process 26
Based on the ARP 2600 voltage processor
Process 26 features two separate voltage processors.
The upper voltage processor features four inputs which are mixed
and inverted at the output. Inputs 2 and 4 have their own attenuator.
Input 2 is normalised to a positive fixed voltage source, which may be
attenuated, and appears inverted at the output, useful for applying
negative offsets.
The lower voltage processor features two inputs which are mixed and
inverted at the output. Input 2 has it’s
own attenuator. Input 2 is
normalised to a negative fixed voltage, which may be attenuated, and
appears inverted at the output, useful for applying positive offsets.

I prefer the Song Huei tall trimmers because they have a longer shaft and a white notch.
