# Midi Studio vs KORG Module

The clearest difference is price: KORG Module at Free against Midi Studio's $1.99. KORG Module also leads on rating (4.6 vs 4.0) and ratings volume (772 vs 65). Midi Studio's advantage is review sentiment (64% vs 52%) and iOS requirement (5.1.1 vs 15.6). On update cadence, ads, in-app purchases and monetization model there is nothing between them.

KORG Module is free to download; Midi Studio costs $1.99 up front. Midi Studio sells 10 one-off in-app purchases and KORG Module sells 21 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

KORG Module holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: KORG Module has 772 ratings behind it against 65, so its average is the more settled of the two. Written reviews complicate that: 64% of Midi Studio's written reviews are positive against 52% of KORG Module's, so the app with the better star average is not the one people write more warmly about.

Midi Studio ships an update every 5 weeks, KORG Module monthly. The most recent releases landed on September 26, 2026 and September 27, 2026 respectively.
