thanks for this tip! ..some time ago I grabbed for free their Sie-Q plugin.. very nice and smooth sounding EQ!! but did not know about this tremolo offer..
I would suggest also to check Plugin Alliance´s deals.. their Noveltech character for 9 USD I find amazing.. also other deals are pretty interesting..
and also through Plugin Boutique you can grab Izotope´s Nectar Elements for only 31,66 €
ps: let alone Toontracks offers, hehe...
