enable Encore performs real-time tuning for a range of
instruments, as well as presets for each instrument in a variety of styles.

You can transpose, use common jazz and orchestra references or even enter
your own custom frequencies for unlimited flexibility. enable Encore
automatically determines your instrument / string's current frequency to
high accuracy, and tells you the corresponding musical note. Use the
transposition facilities to aid you in writing music or transcribing pieces
you don't have sheet music for. Learn to "tune by ear" using the Play Tone
feature, which generates the note you are trying to play while you tune to
it.

enable Encore comes complete with an integrated metronome - providing a
range of preset speed styles (Adagio, Moderato, etc.), accents, output
instruments (drums, clapping, etc.) and even facilities for custom speed
intervals and your own real-time recording. Use Encore's metronome to
practice with a backing track: simply press record, play your own backing
riff and then loop it.
