In the Edit Panel you can specify the parameters for your acts. The Edit Panel consists of a column with buttons named loop 1-4, seq 1-2 (step-sequencers), (external) stream, distortion, delay, am, and fm. Selecting loop 1 in the column displays the editor for loop 1 on the right. Selecting distortion in the left column displays the editor for the distortion effect . With these editors you can tune the settings of the loops or effects, and therefore specify the sound parameters of your acts.
In the Edit Panel you can look at the adjustments of all acts, but you will only be able to change parameters in the acts, which you did reserve beforehand.
In the Grab Panel your nickname is displayed in the status line of the acts you reserved.
