VST Amp Rack causing click at beginning of track

Hi there,

First post here. I am doing the final mix of my sons album, using the export function. Mixing to 16 bit wavs.

At the beginning of tracks which use the built in “VST Amp Rack” insert I get a click at the beginning of the mixed track. Doesn’t happen on tracks without the VST Amp insert. Also happens if a track using this insert comes in part way through a song, with a click as the track starts.

Anyone had this problem and got a workaround / fix.

Any suggestions gratefully received.
