The Software component is a smartphone app, which can be downloaded at the Apple AppStore for iPhone and iPad devices. The app is a MIDI controller & synthesizer, which features 60 different MIDI instruments. The app developed by Brainventions, Inc. is a member of an entire family of similar apps designed for Making Music in Motion. Check out Sk8SoniX (a.k.a. MusiSk8s) for ice and roller skating, MusiShuZ for walking and dancing and MusiFace for making music with your facial expressions.

The Hardware component is the Musical Braces (MBraces). It consists of a pair of wireless Bluetooth numeric keypads attached to hand braces. Each of the keypads has 22 keys. Some of the keys are mapped to musical notes in an octave (all 12 white and black piano kyes are available). The remaining keys trigger essential control functions such as MIDI instrument changes, octave changes (up and down), all types of chords, vibrato, tremolo, glissando and other musical effects.

Unlike a regular piano keyboard, the keys on the Mbraces keypads are arranged in such a way so that you don't have to move your palms left or right in order to play all the 12 keys in an octave. In this key arrangement you can reach each of the 12 keys plus a high Do (C5) using only your 4 fingers (no thumb involved) by flexing and extending them over three rows of keys. All of this can be accomplished while keeping the palms free and your fingers over the keypads.

The thumbs can be used to lightly touch the inner corners of the keypads so you can find a reference point for your palm and fingers positions with respect to the keypads. The pinkies can also be used to occasionally (when not being used to play notes) touch the outer corners of the keypads for positioning reference. In MusiMoto v1.2 the thumbs are used to chose chord types such as Major, Minor, Major-7, Minor-7, Diminished, etc.

Version 1.2 of the MusiMoto app allows only one instrument to be played at a time (due to iOS 14 API limitations). To go around this limitation you can load the app on two different iPhones/iPads and pair each keypad with a different iPhone/iPad. This setup also allows you to play the same MIDI instrument in different octaves at the same time. In future versions you will be able to play two instruments together (or one instrument in different octaves) in a single app.

The newly introduced in v1.2 MusiMotoSat hardware includes a 2-axis thumb stick with 4 restricted quadrants Up-Down & Left-Right. Pushing and holding the thumb stick in one of these quadrants when you press a note key allows you to play chords or arpeggios instead of a single note. The basic chord types are mapped to Major-Minor & Maj7th-Min7th or variation of those depending on the instrument that you have selected to play. Some instruments can play additional chord types such as Diminished, Augmented, Sus, 6th, 9th, 11th, etc.

The newly introduced in v1.2 MusiMotoSat hardware also includes a Motion Processing Unit, which captures in real time the attitude of the MBraces (Pitch, Yaw, Roll) and transmits it to the MusiMoto app. These data stream is used to implement strumming chords and arpeggios, vibratos and tremolos. Use the [enter] key on the keypad to toggle between None, Vibrato or Tremolo mode and wiggle your wrist or move your arm up and down to experience the effects while playing notes or chords/arpeggios.
