8Mode SoftSN Machine
Pre-release of a hardware emulation of the Texas Instruments SN76477 “Complex Sound Generator”. This was a popular analog/digital hybrid chip released in 1978 and was used in Space Invaders, Vanguard and numerous toys. This module simulates analog circuits including 4 RC oscillators and voltage/digital inputs into a chip emulator. The emulator is based on open source from MAME Arcade.
I made this because I’ve been obsessed with VCVRack and I also have great memories of playing with the SN76477 when I was a kid. You could get this chip from Radio Shack in the 80s for like $15. I got it to make all sorts of sounds! So it’s a little nostalgic for me. I think that it’s extremely close to the real thing including all the quirks.
Here is where I’m at with the module:
- Source and Linux/Win/Mac Binaries available (Thank you Dmitry Wolf and @pgatt for Mac Version)
- Hoping to get some input from others in the next few weeks and see about listing on the Plugin Manager
