Report "I purchased a Korg 168Rc Edit from Sound Tower.com it's basically a visual way of interpreting the Korg 168 Digital Mixer, you are using the MIDI functions to control the MODES, PARAMETERS of the 168. If you go to SoundTower.com you will see the EDIT and the picture will show you what is available, but that's all, how the tools in the tool bar functions, is beyond me. There isn't even a manual to describe the functions. Below are the tools available for use with EDIT. 1. Req Mode (Required Mode) 2. Program Librarian 3. Receive Current Program 4. Send Current Program to 168RC Mixer 5. Effect Configuration 6. Faders 7. Equalizer Setting 8. Group Bus - Master 9. Aux Out Channel 10. Effects 1 & 2 11. Midi Receive (Disable) 12. Toggle Meters Display on 168 Mixer"
