Lower on a key plays louder; drag up on a held key to open the sound. Top rows are lush chords, bottom rows single notes. Slide sideways to bend, drag up to brighten and swell, press harder where your screen senses it. Swipe up or down a chord column to strum, tap a string to pluck, slide sideways on a held string to bend it. Slide along a string for continuous pitch. With Auto-bow on, drag up for more bow; turn it off and bow by moving your finger up and down. Left to right is pitch, bottom to top morphs the vowel from ooh to ee. Every finger is a voice; the stack adds harmony. Lower on a pad hits harder. Hold with note repeat for rolls and slide up or down to change their strength. Tap the tone fields. The center is the ding. Notes follow the key. Slide for liquid legato, drag up for brightness and vibrato. Notes stay in key. Tap harder for a harder finger pluck, slide along a string for glissando. Pitch and mod wheels work on every instrument.
