User Reviews

Sweet MIDI Player is praised as a durable, feature-rich MIDI player with strong sound quality and easy playback, plus robust file management and solid external-device support. Common drawbacks center on licensing across devices, confusing IAPs and purchase restoration, a dated UI with hidden controls, and several feature gaps around soundfonts and multi-soundfont loading. Overall, it remains a reliable choice for managing large MIDI collections and teaching or performing with hardware synths, but users should expect some setup quirks and licensing friction.

Pros

Reliable, long-standing MIDI player with years of positive use
Excellent sound quality and rich playback controls, including tempo/velocity scaling and slow-down
Flexible file management with easy import and the ability to use your own soundfonts
Strong compatibility with external hardware synths and MIDI DAWs (e.g., MIDI clock with Logic Pro)
Good for teaching and live use due to ease of use and practical features

Cons

License and purchase handling across devices is confusing: Mac vs iOS are separate apps and purchases are not always transferable
Restoring purchases across devices or via Family Sharing can be problematic
Settings and advanced options can be hard to find; the UI feels outdated and discovery is poor
Soundfont handling is limited (e.g., cannot load multiple soundfonts at once) and overall soundfont quality can vary
Pricing and IAP clarity sometimes feels opaque, with reports of high upfront costs for full features and 'what you get' not clearly explained

i use this app all the time, it’s probably the best midi player for me on my iphone. i want to use it on my mac, but the problem is i cannot redownload this on my mac because the mac version is listed as a separate app than the ios version. so, if i wanted to use this on my mac id have to pay again to use it. which, i am not going to be doing. i use the trail version of this from the website instead on my mac. it’s annoying that i can’t hear the last quarter of a song just because the mac version is separate from the ios version.
