Roland SH-3A

The SH-3A is a monophonic analog synthesizer that was manufactured by Roland from 1975 to 1981.[1] It is unique in that it is capable of both subtractive synthesis and additive synthesis. Two LFOs and a unique sample-and-hold section provided capabilities not found in competing self-contained synthesizers of the time. The SH-3A was Roland's first non-preset based synth. It was unique for its time in that it offered mixable waveforms at different footages. The predecessor, the Roland SH-1000 could also do this but didn't offer as much control as on the SH-3A. The rhythmic pulsing in the Blondie song "Heart of Glass" is an example of its sound.

Contrary to common belief, the initial version "SH-3" did not infringe on the transistor ladder-filter patent of Robert Moog. It used a diode filter like the EMS VCS 3. The SH-3A does use a transistor ladder-filter and as a result can generate Moog-like sounds.

Notable SH-3A users

gollark: CC workflow for setting up a computer to do things:- (auto)craft computer- place computer- write code/download code onto computer as startupOC workflow:- figure out what cards/other components it needs- queue autocrafting for everything- wait a while while autocrafting runs, and possibly converts some coal into diamonds- pull autocrafted stuff out of ME network, put into computers, be sure to get the right items- find openOS disk, disk drive- install openOS- write/download code- either move code to `boot` or work out how `rc` works
gollark: I play on servers. I can't just edit the recipes.
gollark: Even with autocrafting I still have to queue up all the parts and fetch them from storage and install them every time I want a new computer.
gollark: I mean, personally I just find it less annoying than OC because I don't have to microcraft (or program AE recipes for) 89126871258 parts.
gollark: > feel free to unleash your wrath on CCNo, I like CC.
