The 1.23 version of traumbaum for Mac was available to download on the developer's website when we last checked. We cannot confirm if there is a free download of this app available.
Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe. The application lies within Audio & Video Tools, more precisely Music Production. The actual developer of this free Mac application is Afra Masuda.
From the developer:
'traumbaum' is an ever-changing piano piece with no end. If you want to relax yourself with some calm piano music, just launch this app, and you can listen to it as long as you like. You can click the rotating circle to pause and resume the music. By dragging down from the rotating circle, you can set the sleep timer. The music will end at the approximate time you have set.
You may want to check out more Mac applications, such as V-Synth Librarian, M-Audio Key Rig or Mandala Virtual Brain, which might be similar to traumbaum.
