## What is Trombone Piano?

Trombone Piano is a touch keyboard. Touch the keys to play. Slide along the mahogany strip to move the keyboard. Two voices: TROMBONE plays the trombone and shows the horn, and PIANO plays the piano. SHOW POSITIONS prints the slide position on the keys a straight tenor trombone can play, and moves the slide on the horn. The staff uses tenor and bass clef for trombone, and treble and bass for piano. With MIDI on, the keys are sent out and this device stays quiet. A Mac can receive them over a data cable. A computer on the same network can receive them. Bluetooth sends notes only after advertising is turned on. GarageBand on a Mac uses the iPad as a MIDI input after the iPad is enabled in Audio MIDI Setup.
