It’s a tiny little chip synth! The YM2149 is a neat little chip that was used in various retro arcade machines and consoles, including the Atari ST. It features three adjustable voices. They are mapped to MIDI channels 1-3.
V2 is finally here! Improvements over V1 include:
- TRS MIDI (Type A) input, adapter sold separately
- Balanced audio output (66/33, 33/66, and 50/50 L/R on the three output channels)
This synth is wrapped in clear heat shrink tubing for protection and durability.
A web-based patch editor is now available! Due to a dependance on web midi, only the Google Chrome is supported. It’s highly recommended you backup the default presets before messing around! Check it out here: https://2xaa.github.io/ym2149synth-web-editor/
A Max for Ableton Live plugin is now available! Check it out: http://www.maxforlive.com/library/device/4520/ym2149-synth
