Verdict

The call

The clearest difference is price: MIDISynth Control at Free against iDousyn's $9.99. MIDISynth Control also leads on review sentiment (64% vs 34%) and update cadence (every 3 weeks vs every 2 months). iDousyn's advantage is rating (4.2 vs 3.4) and ratings volume (159 vs 12). On ads, in-app purchases, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

iDousyn holds the better App Store score, 4.2 against 3.4. That said, the two scores are not equally well evidenced: iDousyn has 159 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 34% of iDousyn's written reviews are positive against 64% of MIDISynth Control's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

iDousyn ships an update every 2 months, MIDISynth Control every 3 weeks. The most recent releases landed on October 13, 2026 and September 23, 2026 respectively.
