Peter.
before i reply to your latest posts back to me , and thanks for partaking in this thread, i would like to go on the record with a couple of things.
1. i have the utmost respect for how far you have brought your company and its products.
its not easy building a company. kudos to you.
also let me say you have a great team of people.
2. ive opened the eyes of more than a few musicians over the years , as to what can be done useing your products who were just not aware of what could be achieved. many times i would just sit the person down with me and open up powertraks and/or biab or rb , and watch their eyes light up as i went through building the bed tracks of a song and then adding the "cherries" on top etc.
3. i'm not trying to paint myself as a better musician or songwriter than anyone else on these forums. frankly i struggle to do the best i can in doing songs. there are many musicians on here way more capable than myself. of that i'm sure. i'm not trying to be a "smartie".
now back to the thread.
------------------------------------------------------------------------------------------------------------------

the main issue for me is how to correlate the sections of a song in biab (or rb) with the markers in the daw i use. in my case the popular reaper. <<and i dont say that to knock rb which i like.

(thank you pipeline for partaking in this thread).

Peter, you will notice in PL's tabbed graphic < > arrows on the tab line. i happen to like this as i can work on various sections of a song as i need to. also an important point is , because the song is broken up into tab sections there wont be a slew of chords in each section.
i also like in that tab view the capability of just clicking the mouse on the tab to get whatever i want > intro or verse or break or whatever i have named.

lets examine another possibility peter.
ie another possible view akin to piano roll view whereby chords linearly along the top horizontally and instrument choices down left hand side vertically. includeing the new 16 trak biab approach.
and instead of those cel areas in piano roll, cels
users can clik on to either do a partial regen or mute part of a bar and sorta the features of F5 currently.
(no i'm not saying replace piano roll which is a different purpose, i'm just saying useing its layout as a view model.)
maybe Pipeline could do a graphic example ? as due to my vision impairement i'm useless at graphics.

Peter in your example those section texts certainly help
the correlation i need to daw markers. i'm useing layers currently for notes etc.

regards.
