The picture above shows the chord symbols I asked about. CΔ7, Co (7), Cø7,C-7, for Cmaj7, Cdim7, Cm7b5, Cm7.
The picture is from BIAB help file under "import". I accidentally found it while I was searching for something else.
This shows that it is possible to use typical jazz chord symbols in the main window of BIAB.
But how do you do it?
Thanks for any comments.
