+1 on Reaper.

I know some prefer to use Realband when working with the Realtracks because of its multiriff function before moving to Reaper. I however generate and import all BIAB wav files to reaper directly and create my own version of multiriffs in Reaper. Once set up in Reaper cutting and splicing Real tracks is much faster than using the multiriffs function in Realband. The process also allows for much more creativity and the development of more originality than is possible just using the multiriff function in Realband.

Reaper also allows you to change and customize its menus to match your workflow. You can create custom skins or download a user created skin some of which are outstanding (Something PGM should consider implementing in BIAB).

Many fans of Reaper and for good reasons as listed in this thread.
