期待どうり

声が入ってない楽器だけの音源が欲しかったのですがインターネットのどこにもなく、困っていたのですがこのアプリは分けてくれるだけでなく、細かく楽器ごとに音量調節ができるのでとても素晴らしかったです。無料ですぐ使えるので本当に助かりました。

すぐ閉じてしまう

課金しましたがすぐアプリが閉じてしまう。midiもほとんど合ってない。

Great app

I’ve been using this app since the day it was released. I don’t know why people are complaining that they had to pay an extra $4.99 to use more features of the app as there are no advertisements, no overpriced subscriptions, the app is always updated, it works, and it is on my top 15 must have iOS audio apps. I’ve been using iOS audio apps since 2011 (plus beta testing) and I’ve seen wonderful apps go through putrid changes, go to subscription service even after you’ve paid for them, and some have no updates (basically wasting your money without it ever working on a new device). Not this app- truly fabulous. I adore this app and appreciate the updates!!
