Question: When using CLAP plugins with stepped parameters via CSI, I often run into mapping issues (not moving through steps as expected). Is this due to how CLAP handles stepped parameters vs VST3, something with Reaper’s API, or does CSI need to handle them differently? I've heard of AU users running into similar issues. Just not sure where the issue might stem from.

If you can reproduce the issue using a freely available CLAP, and ideally a ReaScript calling TrackFX_SetParam()/ etc, that would be a good step in sorting that out. 1 Comment...

Question: If you automate a JSFX parameter and it causes zipper noise because of the sudden change in parameter value but then it stops once you are done dialing in, shouldn't that be a concern with regards to my audio fidelity on export? A couple of nice jsfx effects put there are like that when you check phase in plugin doctor or bertom analyser. Smoothing causes slider to be a bit slow for automation, what's your suggestion? Should I ignore since I usually don't automate such sliders?

If it makes the zipper noise when changing, and doesn't make the zipper noise when not changing, then as long as it's not changing it should be fine. If you need to be able to have those parameters changing during playback, then someone should fix the JSFX in question... 1 Comment...

Reply on April 2 2025, 1:05pm (edited at April 2 2025, 1:13pm):

 edge_gap = GetEnvelopeInfo_Value("I_TCPY") - GetEnvelopeInfo_Value("I_TCPY_USED");
 ai_label_ypos = GetEnvelopeInfo_Value("I_TCPY_USED") + GetEnvelopeInfo_Value("I_TCPH_USED");
 ai_label_height = GetEnvelopeInfo_Value("I_TCPH") - GetEnvelopeInfo_Value("I_TCPH_USED") - 2*edge_gap;

Question: Some courts have decided (quite bizarrely from a foreigners perspective) that buying votes is legal. Do you think it's legal to take the money and vote the other way?
