Include Control Change (CC) automation data and Program Change (PC) events in MIDI exports. This information is part of the MIDI specification and it could be included in the exported MIDI files to work easily with external hardware.
This request is not about converting each and every automation to CC, since implementing this might be non-trivial. It is about CC automation that was explicitly created as CC automation.
Bitwig MIDI export supports only for note events, not for CC automation and PC events. The lack of this feature complicates the workflow when using Bitwig with external hardware, in particular with hardware sequencers/grooveboxes.
Many of them can import SMF, but for data exchange users have either to record their patterns (with CC data) back and forth, or to use another DAW.
Bitwig aims to streamline your creative process. It also puts its emphasis on integration between hardware and software. This request is about better and more fluidly controlling hardware with the MIDI data that the software is capable of producing.
Only recording MIDI back and forth. However, this is very time consuming even for relatively simple projects, so it is not really an option.
Cubase, MusE, and probably more DAWS.
