I’m running Logic Pro 10.7.4 on MAcOS 12.3.1. After u^grading to Scaler 2.7.0 I found ou that I had no sound with the scaler2 stereo au-instrument: even when playing a predefined chord sequence, or clicking on the GUI keyboard (the felt piano sound is loaded, the channel is not muted, and when replacing by another plugin I get sound).
I also figured out that I had no MIDI input either.
I tried to remove all Scaler2 VST and au-component files from my Library, and reinstalled Scaler, but no luck: still nothing working.
However, I didn’t have to register again, so I think I’ve not correctly uninstalled Scaler.
By the way, I also tried on Cubase12: and still no sound…
I have the same issue with Scaler 2.7 and 2.7.1 with both Ableton and Reaper. Running on Windows 10. No audio coming out. No midi input. No midi sending out either when playing predefined chords.
Tried clearing cache, rescanning vsts. Tried uninstalling and reinstalling.
Reverted to Scaler 2.6 which works fine.
Could you please check what MIDI channel settings is used in the preferences panel in the side menu?
It could be that the plugin isn’t being initialized properly by the host. In your music software you can check for the audio settings and try with a different sample-rate or block-size. Changing those settings will reinitialize the plugin.
