The lite version of Bias Amp is on Focusrite Collective for Focusrite clients until May 31.

It is amazing.

For one thing: the acoustic amp.

Before you officially "purchase it" as the final step and render it an official version in your DAW, make sure you find and save the Acoustic camp in the clean amp collection (as Acoustic Amp2 for example) and/or as a VST preset while you are still in demo mode or it may disappear from your future amp choices when you perform all the registration steps.

It will work magic on both acoustic audio and acoustic midi.

Get it now if you can.
