Streambyter: midi range

cokomairena

Hey

How one would do to set some midi note boundaries so if a note is higher than that limit, then transpose an octave down.

If it’s lower than the lower limit, transpose one up…

Should be easy right.

See this post to give you the general idea of how transpose some notes based on criteria. You would change the actual tests but the concept would be the same.

In short :
if note is in the range of interest
transpose the note and block the original

This will do it. Copy/paste into a StreamByter window and Install Rules. Be very careful with the spaces between tokens. As show, it transposes all notes into the two octaves around middle C; you can adjust as desired. Notice that the script edits the Note On and Note Off messages and allows them to pass on out. You can test it using StreamByter's MIDI monitor (magnifier icon).

#FoldOctaves

# ^C3 is middle C in Streambyter
If MT < A0    # process note on and off messages
   While M1 > ^C4
      Math M1 = M1 - $12
   End
   While M1 < ^C2
      Math M1 = M1 + $12
   End
End

This works great. Thanks
