At the moment it seems as MIDIBox processes data this way...

File > MIDI File Notes > MIDI Pass-Thru

This can be problematic if I want isolate the left hand in a piano sequence by using the Output Note Range functions as the transopistion happens before that filtering. It would be handy to be able to reverse the processing sequence to this...

File > MIDI Pass-Thru > MIDI File Notes

This way I could load a piano motif, filter out the left hand bass notes, then apply the transpose to keep all the parts correlated. I know I can probably get around this by creating a new "top level" MIDI layer with MIDIBox in, but this seems a far simpler way.

I'm not sure I understand you. There is no sequence; MIDI pass-through and file playback work in parallel.

Can you explain what you're trying to achieve in more detail? When you say "filter out the left hand bass notes", do you mean notes played back from the MIDI file, or bass notes you're playing on the keyboard.

Sure...

I have a MIDI file with a single MIDI channel in, it was played in with a piano controller. I set the Output Note Range in MIDIBox to Exclude Notes with the range C2 to G8. This would reduce a part played in for piano to just the left hand, or bass part.

Then I want to have those filtered notes transpose to whatever I physically play in all the way up the keyboard whether it's C-2 or F5 etc, so I enable Transpose in the MIDI File Notes section.

This works, until the notes I physically play in go in to the filter range (C2 to C8), and nothing plays because it's all happening at once in parallel. If I physically play C4, nothing plays. The behaviour is the same as is if it was a serial process of transposing the MIDI file, then filtering.

If the processing was done in serial for these two components only, with a toggle box to reverse the sequence in which they happen (transpose before range, or range before transpose) everything could still work as it does now, and the pattern would transpose up or down the full range of the keyboard if that's the behaviour that people wanted.

Let me see if I understand you correctly. You have a MIDI file a piano sequence played hands-together, but you would like to play back only the left-hand part, with key-transpose enabled. You don't want to hear the right-hand part from the MIDI file at all. Is this correct?

If that's the case, why not just edit the MIDI sequence (e.g., in a DAW) to remove all the notes played originally by the right hand, and then load the edited sequence into MIDIBox with key-transpose on, leaving the output note-range wide open at C-2 to G8?

It's purely a usability and workflow thing I guess. I like to mess around and expirement in Unify standalone before moving in to a DAW, it means I don't have to think about creating and naming an entire project structure before actually having an idea of what the project is about, and it's a heck of a lot quicker to work that way. I have a lot of MIDI loops I've built up over the years and I've found myself just dipping in and out of them with MIDIBox.

I know it's probaby a little on the "edge case" side, but just throwing ideas around πŸ™‚

Have a look at https://www.midieditor.org/ for a free MIDI file editor for Windows.
