Zensphere doesn't show up in my DAWUpdated 6 days ago
Zensphere is an instrument. In Ableton and in the other hosts, look in the Rapid Flow folder under instruments, not under MIDI effects.
If it is missing, rescan the plugins. In Ableton, hold Option on a Mac or Alt on Windows and click Rescan, so it does a full scan.
On a Mac, open System Settings, then Privacy & Security. If Zensphere was blocked, click Allow Anyway, then rescan. Restart the computer if it is still missing, and run the installer again.
The manual is here: Zensphere manual
