# Music Studio vs KORG Module Pro

The clearest difference is price: Music Studio at $14.99 against KORG Module Pro's $39.99. Music Studio also leads on iOS requirement (12.4 vs 15.6). KORG Module Pro's advantage is rating (4.6 vs 3.7) and chart position (#171 vs unranked). On review sentiment, ratings volume, update cadence and ads there is nothing between them.

Music Studio costs $14.99 and KORG Module Pro $39.99 up front. Music Studio sells 6 one-off in-app purchases and KORG Module Pro sells 20 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

KORG Module Pro holds the better App Store score, 4.6 against 3.7. Both are backed by a comparable volume of ratings — 421 and 1.2K respectively. Written reviews complicate that: 69% of Music Studio's written reviews are positive against 64% of KORG Module Pro's, so the app with the better star average is not the one people write more warmly about.

Music Studio ships an update every 2 months, KORG Module Pro monthly. The most recent releases landed on October 16, 2026 and October 14, 2026 respectively.
