can't apply VST to an item - what's wrong?

hello in my new song, a have a track with a VSTi synth. there's a small part of that track where i want to use additional filter from PSP Nitro. so i splitted my MIDI track and tried to apply an fx only to the short part by right-clicking that item -> Take -> Show fx chain for active take -> choosing Nitro FX. everything seems fine, but there's no filter sound - it's still just a synth. yes, i loaded a preset to the nitro. so... what's wrong? how to apply an fx to only a short part of the track? best regards

AFAIK, the item FX are applied before the track FX. So the PSP Nitro FX is applied to the MIDI notes (=> no effect) then the output is sent to the track FX (the synth). What you could do is: -- add PSP Nitro to the track after the synth, -- add a Bypass envelope for PSP Nitro, -- enable it for the section where you want to apply the FX. HTH

.. yep, if you split it up
