I just switched to Reaper from Cakewalk, because there were issues with Chordjam. Chordjam works fine with Reaper, but I can’t audition the Playbeat’s presets there. The sound breaks off after less than a second listening into the preset.
I can host Playbeat in Unify from PluginGuru and there I can audition the presets though. So this is a work-around.
But I thought you should know this issue with Reaper.
I run my PC on Win10 Pro everything uptodate and the newest Reaper version.
All the best!
