I see someone on ebay has started making a profit selling ribbon controllers for CV gear. I am very interested in making my own, but i am trying to think of a real good ribbon material to extend a good foot hopefully longer. I don’t want to use SVHS tape. I feel it would tear or wear too much.
You can measure resistance and mark off the notes and print keys on the box. This seems like an awesome extra controller for pitch or filter. As you see in the links some have added extras for two note and/or sample and hold.
please respond with thoughts on this project so we don’t have to pay someone else to make this apparently inexpensive item.
ps. the schematics in these links show ic’s but don’t give specifics. I guess i understand these are op amps (most likely-i think) But what kind of configuration. It looks like they may be inverting but i have only been studying linear for this past semester.
