-
- Create empty project
-
- Add an audio track
-
- add an TestGenerator with sawtooth and an Fx plugin - e.g. a Filter
-
- Add an stepmodulator, draw some curves, set “Slope on all edges” and “Slope amount” to 100% and assign to a couple parameters of the filter - modulation should be heard
-
- Add an empty track of any kind
-
- In the Studio Setup/Audio system activate ASIO-guard, set its level to High
-
- listen to the modulations while the track with the test tone generator is in focus (v.1)
-
- listen to the modulations while the other track is in focus (v.2)
-
- listen to the modulations while the track with the test tone generator is in focus and the project is played back (v.3);
Result:
v.1 is smooth, v.2 and v.3 aren’t.
There is no issue when Asio-Guard is disabled or when Asio-Guard is at lower level than High.
Tested with third party plugin - Minimal Audio: Rift Filter Lite
Expected behavior: modulation should be smooth and sound the same in any of the scenarios above.
