selected track.

that you can concentrate on playing, not the mechanics of driving the program.
Autodrop is activated by clicking on the Autodrop button in the Transport bar.

when you launch Logic, and serves as a starting point for your songs and projects.

bandpass filter This filter only allows the frequency band centered around the cutoff
frequency to pass, while frequencies that lie further away (the lows and highs) are
filtered out. A sound that contains lots of mid range frequencies is the result. Also see
filter.
band rejection filter This filter cuts the frequency band centered around the cutoff
frequency, while allowing the frequencies that lie further away to pass. The mid range
frequencies will become softer and the lows and highs remain unchanged.
