I searched but couldn´t find a solution to this. In previous versions you could click on one button on the top of the mixer to bring up a vst instrument, i can´t find this function with the new mixer. Help please :)
On the strip/rail there is a lil 'e' button.
(directly under the 'solo' button)
1-Clik and hold on it.
2-Option clik (on Mac here) on it.
