If your ok with your bassline being in Mono cant you use the channel converter in soundforge to convert stero to mono and use the preset "Use left 100" (or right depending on which works)...

Just a thought of a way round it till you fix it.....

The fruity way loopdon showed me works really well and if your working soley in Fruity then its perfect...

But I been creating my basslines with midi tracks and soft synths in Acid 4 so its a bit of a bastard trying to export loops then pop em into the fruity slicer and side chain to a kick then re export again.

Does anyone know if theres a peak controller or simerlar plug to the one in fruity that you can use in Acid 4.0 to link a kick to say the waves C1 for example?
