MIDI export organ pedal clipping massacree!

OS: macOS 10.15, Arch.: x86_64, MuseScore version (64-bit): 3.4.2.25137, revision: 148e43f

Organ, like all MS instruments, is rendered as one channel (at a time), which is inadequate for controlling either real or virtual organs from the score, but interoperability tools such as mine prefer to focus on staves (seen as "Tracks"), not channels, and this generally works out ok. But the MuseScore unison-clipping-avoidance code sees "conflicting" manual and pedal notes as a problem on this account, and, quite unlike real or VPO organs with or without Tirasse (pedal coupler) drawn, the manuals passing through a pedal note "restrikes" the pedal, a gesture which, in concert, would cause the organist to be "restruck". But that's not the worst of it.

Confused in its little fiefdom, after the "brief interruption", the code continues the pedal note on the manuals! "They're all the same channel, aren't they! Why isn't that right?" Well, no, after midi post-processing.

My suggestion to a student of mine whose beautiful piece was marred in this way (pedal went silent in the middle of a note) was to add a second pedal-only "MS organ" and move the pedal notes to it (attaining a different channel to avert the unison-collision code). Depending upon compositional texture, three (or more) separate "organs" might be necessary. In any case, this presents a real problem requiring deep midi knowledge to even work around. Don't know what to suggest, but the attached score and midi are unacceptable to me.

I hate to say "more user input to the unison-collision-manager", ...but ...
