I can do it easy in the Plugin in Reaper using Instructions as it's playing the wma section directly and not loading into RAM. I can do it in Reaper using ReaTrak-biab-drums-gui-audio-demos.zip or ReaTrak-instant-trak-creator-gui.zip
Sane deal with RealTimeSignatures I can make any time signature in a UserTrack then fit it to the DAW real time signature by changing the tempo.

Adding an escape function to PG's endless double time development loop will solve the issue:
Code
function BuildDelphiBiab
  spend 6 months programming Win Biab
  goto BuildMacBiab
end

function BuildMacBiab
  spend another 6 months doing the same thing on Mac
  if sick and tired of this
    goto JUCE
  else
    goto BuildDelphiBiab
  end
end

function JUCE

  JUCE is a cross platform framework allowing a single codebase to compile to native applications and plug-ins with the 
  same user experience on Windows, macOS, Linux, iOS and Android, across both desktop and mobile.

1-All time signatures
2-Modern customizable menus: eliminate redundancy.
3-All genres of music including EDM, R&B, trance, ambient, soul, hip hop, house, acid jazz, etc.
4-A more intuitive workflow.
5-Drop DXis and only use VSTis
All of the above and probably more is a stable VSTi.

Logic, Reaper, Abelton, Pro tools- the environments serious music software needs live in.

Quit trying to sell a DAW. If it works so well with BIAB make those features work in the plug in for mainstream DAW’s.

IMO BIAB’s growth future is as a plugin to the above environments.

Don’t rebuild the standalone UI. That’ll take million$. Instead Phase it out by attrition.
As suggested by others. Fix the broken stuff, simplify(not rebuild) the UI.

Spend dollars on the future, not the past.
Real Tracks, Super MIDI, Styles . Those things are what makes BIAB great.

Most computer users use a phone most of the time. DAW’s are available for tablets now. Don’t miss the coming convergence of software to the mobile OS platforms.
Not sure what the stratedgerie to do this is, but recognize in a few years phones will have all the cpu/gpu/ram they need to run this stuff.
