Adaptive Use Musical Instruments (AUMI) software interface enables people who have very limited controlled (voluntary) movement to independently engage in music making. The Adaptive Use Musical Instruments software interface enables the user to play sounds and musical phrases through movement and gestures. This is an entry to improvisation rather than “hitting the right notes” or playing set pieces of music. Instead, the software uses music as a way for participants to express a range of affects, both by themselves and in response to, or in conversation with, others. While the AUMI interface can be used by anyone, the focus has been on working with people who have profound physical disabilities. In taking these participants as its starting point, the project attempts to make musical improvisation and collaboration accessible to the widest possible range of individuals. This approach also opens up the possibility of learning more about the relations between ability, the body, creativity and improvisation, from within a cultural context that does not always acknowledge or accept people with disabilities. This iOS version of AUMI runs on devices with cameras, and can run on iPhones, iPod touches, and iPads. A large assortment of sounds can be triggered with configurable amounts of sensitivity. AUMI also can be used as a MIDI controller to access other iOS based synthesizers or external equipment (using the iPad's Camera Connection kit or via Core MIDI over WiFi.) AUMI can also import audio from other iOS or desktop apps to be used as melodic or percussive instruments. AUMI can capture a record of the movement in the session, which can be exported and turned into reports in a clinical setting.

Verdict
The clearest difference is rating: AUMI at 5.0 against SoundForest's 4.2. AUMI also leads on in-app purchases (none vs 1). SoundForest's advantage is ratings volume (449 vs 4) and review sentiment (67% vs 50%). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. SoundForest sells 1 one-off in-app purchase. AUMI asks for nothing beyond the download.
AUMI holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: SoundForest has 449 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 50% of AUMI's written reviews are positive against 67% of SoundForest's, so the app with the better star average is not the one people write more warmly about.
AUMI ships an update every 6 months, SoundForest every 2 months. The most recent releases landed on September 25, 2026 and October 21, 2026 respectively.
