Thanks for your reply.
I was able to use POWAIR with OtsAV with the help of DDMF’s Virtual Audio Stream.
Since OtsAV doesn’t support VST plugins directly, Virtual Audio Stream is what allows you to place POWAIR after OtsAV and before your computer’s audio output.
Here are the steps:
Download and run POWAIR and Virtual Audio Stream.
Click the speaker icon on your taskbar, click ‘Open sound settings’ and set your output to ‘Steam 1 (DDMF Audio Device)’.
Launch OtsAV and play some music.
Launch Effect Rack.
Click Plugins --> Edit list of available plugins --> Options --> scan for new or updated VST3 plugins --> Scan - let Effect Rack complete the scan, if it crashes, reopen and scan again until it finishes.
Click Options --> Change settings for first stream.
Set device type to Windows Audio, set the correct output, set the input to Stream 1, and close the settings windows.
Right-Click somewhere in the middle of stream 1 (first one on the left) and select Sound Radix --> POWAIR
Right-click at the top of the stram and select Audio Input and at the bottom right-click and select ‘Audio Output’
Make the connections as shown in the picture below and you should be hearing your music through POWAIR!
Double click the POWAIR box to open the POWAIR’s GUI.
If you have any questions, just let me know.
