We are pleased to let you know that REAPER 6.0 is now qualified by Waves for multitrack recording and playback on Waves SoundGrid systems, via the SoundGrid Driver. We will continue to qualify major versions (6.0, 7.0, etc.) of REAPER for this purpose.

In parallel, development of the Tracks Live multitrack recording software has been discontinued. Tracks Live continues to be compatible with the systems on which it has worked until now (see system requirements). On newer systems, REAPER 6.0 is now the qualified live recording software to use with SoundGrid.
For any queries, please feel free to contact Waves technical support.
