(BUG) MXXX6out & Tonal-Transient Crossover

[levendis]

When using Tonal-Transient Crossover in MXXX6out, and directing the module's outputs to independent plugin outputs, the split with the Transient portion is overblown (very loud). So loud that i recommend not reproducing without level control, like hard limiting, post effect.

i'm using FL Studio, which offers an option to "Use fixed buffer size", in the DAW's plugin wrapper's settings ("Troubleshooting" tab). Engaging that option yields a different result. The erroneous split sounds like it's accumulating, piling up.

With the same processes in MXXX6in6out, the issue doesn't occur.

Win 10 Home
FL Studio 25.1.4
Melda Plugins v.17.05 -- MXXX6out (VST2 & VST3)

The same thing happens in Bitwig as well and for any linear phase crossover too. I reported it a while back, but support couldn't reproduce it. Maybe they'll have more luck with FL Studio.

Reaper is fine on the same system.

Thanks for the verification and identification of another problematic crossover, Held.
Given that you've gotten different results across DAWs, implies that the issue isn't hardware related.

We'll check it out, but it indeed sounds like FL problem. We'll report to FL guys if we manage to simulate it. Please send us a small project to vojtech@meldaproduction.com

Shall do. Expect a zipped project attached to an email within a day or two.

We received the ZIP file with the FL project, which was prepared in a way that made the issue easy to reproduce. Thanks. We identified and fixed the problem - FL Studio does not clear output buffers in all cases, unlike other DAWs (e.g. REAPER). The fix will be included in the next release.

Thank you!
