Source: Behringer UB-Xa User Manual V1.0 (FACE-PRIN-PH1_M_BE_0722-AAF_UB-Xa_A4_EN.pdf, Music Tribe's own file at mediadl.musictribe.com, read from the Internet Archive capture of 5 February 2024, https://web.archive.org/web/20240205102541/https://mediadl.musictribe.com/download/software/behringer/0722-AAF/FACE-PRIN-PH1_M_BE_0722-AAF_UB-Xa_A4_EN.pdf, SHA-1 12391e483470e25d416429eda8e6fa634c7a5cb8), MIDI Continuous Controllers, page 22; USB / MIDI settings, pages 14 and 15. Sliders send the control change most significant part only; the manual pairs each with a fine part (34 to 61) and also lists NRPNs (pages 23 to 29), which are not sent. Several parameters have two control changes (resonance 27 and 71, loudness attack 89 and 73, decay 90 and 75, release 103 and 72, portamento 5 and 84); one of each is on a slider. UB-Xa D (desktop): its quick start guide (QSG_BE_0718-AAL_UB-Xa-D_WW.pdf) mentions MIDI control changes without numbers, and its full manual could not be retrieved intact, so this page is not verified for the UB-Xa D. Panic sends Note Off, All Notes Off (123) and All Sound Off (120), standard MIDI channel messages.
