# iMIDIPatchbay vs KORG Module Pro

The clearest difference is price: iMIDIPatchbay at $14.99 against KORG Module Pro's $39.99. iMIDIPatchbay also leads on iOS requirement (12.0 vs 15.6). KORG Module Pro's advantage is rating (4.6 vs 4.2) and ratings volume (1.2K vs 18). On review sentiment, update cadence, ads and in-app purchases there is nothing between them.

iMIDIPatchbay costs $14.99 and KORG Module Pro $39.99 up front. iMIDIPatchbay sells 2 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 4.2. That said, the two scores are not equally well evidenced: KORG Module Pro has 1.2K ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 67% of iMIDIPatchbay'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.

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