Plugdata-fx CLAP in Fl Studio 2025 outputs all multi out channels in channel 1

[Naskomusic]

ISSUE: Technical Bug

DAW: Fl Studio

OS: Windows & MacOS

PLUGDATA VERSION: Plugdata-fx 0.9.3 (nightly)

FORMAT: VST3

REPRODUCE:

1. Load plugdata or plugdata-fx as a CLAP in Fl Studio 2025.
2. play any audio in the arranger and load a plugdata patch with multi-out (using dac 1 2 3 4 ...).
3. Plugdata-fx will now output all added out's on outlet 1.
4. This can be fixed by disabling all in and out channels in the fl wrapper settings by clicking twice (seemingly also fl related issue)
5. This manifests as a seemingly no-change when using plugdata patches like N-SPEC GATE, where the channels 3 and 4 are phase inverted versions of the spectrally processed signal.
