Hmmm ok Then I'm confused why it would have 16 channels?
TY
Because, the midi specification means that it must respond to any one of the 16 legal midi channels being feed to it. But as Scook mentioned, it will only play one instrument per instance. The same is true of many other soft-synths, such as Dimension Pro and Rapture.
The TTS-1 is a multi-timbral synth and is probably GM/GS compliant with it's channel mappings. Therefore, for example, channel 10 always maps to the percussion instruments. There are also standardized program mappings, so when a GM or GS midi file calls for an acoustic piano, it will call up program number 1, or program number 12 for a vibraphone, etc.
Not all synths are multi-timbral, like TTS is. Therefore, they are one patch/program per instance and do not comply with the GM, GS, or XG midi standards.
