TG300B mode
TG300B mode is a feature on some Yamaha XG devices that provides unofficial Roland GS compatibility.
Yamaha do not document what GS features are supported beyond the list of patches. In testing, it seems to support a substantial number of GS System Exclusive messages, among others:
- GS Reset (switches to TG300B mode)[1]
- Editing the reverb and chorus (type, rate, delay, feedback level, etc)[1]
- Per-part controller mappings, including LFOs[1]
- Per-part voice editing (e.g. adjusting filter cutoff)[1]
- Drum setup editing (e.g. reverb level for drums)[1]
Like the Roland SC-55, the patch set for TG300B mode includes Roland CM-64 compatibility banks. Unlike the SC-55, many XG devices also offer a specific CM-64-compatible mode (C/M mode).
Name
The name refers to the Yamaha TG300's similar "GM-B" mode, but this is a euphemism, presumably to avoid infringing on Roland's GS trademark. Yamaha's own manuals admit it "may not be able to play back TG300-specific song data with complete accuracy", but it is compatible with "MIDI data designed for other computer music tone generators".[2] Also, whereas the TG300's GM-B mode only attempted to be compatible with the Roland SC-55,[3] the TG300B mode provides compatibility with newer Sound Canvas devices, e.g. the Yamaha MU80 TG300B patch list looks more like the Roland SC-88's.[4]
