Quantity: 1 Analog Logic, 2 Analog Shift Register, 3 Multiples, all in one panel.
From Ken Stone’s CGS website:
This module is the analog implementation of some basic logic elements. Instead of dealing with binary inputs, the “logic” is applied to whatever voltages are present on the inputs. When the AND element is fed several voltages, the output will equal the the lowest input voltage. The NAND output will be the inversion around 0 volts of the AND output. When the OR element is fed several voltages, the output will equal the the highest input voltage. The NOR output will be the inversion around 0 volts of the OR output. Apparently the AND and OR functions are the same thing as “peak” and “trough” on old Serge synthesizers, though they are implemented somewhat differently.
This module is an analog control voltage shift register, three stages in length. It duplicates the functionality of the Serge ASR, but goes about it in a very different way. It is great for producing “arabesque-like” sequences, trills etc., when used with VCOs. Of course it’s use is not limited to VCOs only.
Unlike ASRs produced using “bucket brigade” techniques, the CV outputs are constant from the beginning of the cycle to the end — there is no “charge period” in which a brief glide is heard. The CV input/output range of the ASR is approximately +/- 10V.
Modifications:
- Front Panel Express Panel
- Labelled the AND module “Low”, the OR module “High”.
Hi Richard – I’m considering building one of these but I’m confused about one thing – What are the two small boards between the logic board and the ASRs? Also, it looks like Ken has an onboard mixer/processor on the logic board. Do you use that for anything? Thanks
Gary, what looks like two small boards are actually mounting brackets. Look at the right one. You can see how it attaches to the panel under two jacks. This was a bracket once sold by Larry Hendry. As for the mixer/processor on the logic board, that’s only on the version 1.2.
