Source: Roland TR-8S MIDI Implementation Chart, Version 1.10 (Oct. 4, 2018), Roland file TR-8S_MIDIImpleChart_eng03_W.pdf (https://static.roland.com/assets/media/pdf/TR-8S_MIDIImpleChart_eng03_W.pdf): control change list, instrument note numbers (note *1), real-time messages; default channel 10. Only recognized control changes are sliders (Auto Fill In 14 and 70 are transmit only). The chart prints no value ranges, so every slider spans 0 to 127. Alternate note numbers and the Inst Note setting are listed on the page. Panic sends Note Off, All Notes Off (123) and All Sound Off (120), standard MIDI channel messages; the chart marks both as not recognized, so Note Off is what actually stops notes.
