YMCK Magical 8bit Plug
Magical 8bit Plug is a plug-in style software-synthesizer for producing primitive electronic sounds like the old 8bit game consoles. It is released as freeware by YMCK, the popular Japanese Chiptune band.
- Includes 5 waveforms (square, pulse (2 kinds), pseudo-triangle, low-resolution noise)
- ADSR envelope assignment for volume
- Supports pitch bending, bend range variable
- Frequency sweep function
- 32 sounds (maximum)
This plug-in was released a while ago (updated to v0.2 June 19th), but just recently a page with information in English was published.
