# MIDI Designer Pro X vs Knob Lab

The clearest difference is update cadence: MIDI Designer Pro X at every 5 days against Knob Lab's every 4 months. MIDI Designer Pro X also leads on rating (4.6 vs 4.2) and ratings volume (272 vs 13). Knob Lab's advantage is iOS requirement (15.0 vs 18.6). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. MIDI Designer Pro X sells 9 in-app purchases, starting at $1.49 per month and Knob Lab sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

MIDI Designer Pro X holds the better App Store score, 4.6 against 4.2. That said, the two scores are not equally well evidenced: MIDI Designer Pro X has 272 ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 79% of MIDI Designer Pro X's written reviews are positive against 85% of Knob Lab's, so the app with the better star average is not the one people write more warmly about.

MIDI Designer Pro X ships an update every 5 days, Knob Lab every 4 months. Both last shipped on November 6, 2026.
