Security & Privacy Review
Well, after using this for almost 10 years now, it's still my go-to app for learning a drum part. I set out my sheet music and create a loop for each bar or so of music. Then work up to speed the part. When the music is slowed down, it is crystal clear. There are other apps that isolate the drums or guitar or bass, but I found that only useful if I just want to play the part. It really doesn't help me practice like this does. 5 stars.
They made it much worse. It copies all played music onto internal storage. This also breaks internal file picker which now has no way to access the SD card since it starts with the directory of the last song it played. Still great for learning music, but there's gotta be a better way. A great app that I paid for and used for 10 years is spoiled. I want the old version please.
I really love this app. The Spotify linkage gives me access to all my playlists so I can slow down or transpose nearly any song I want. At first I couldn't find the saved loops but then I found out the loops are stored with each song, so you have to first load the song you want to learn, and then all the previously saved loops appear. You can rename them, delete them, etc. You can't export Spotify songs, but you can export songs from your own collection. I haven't found a fine-tuning ability to adjust the start and end points more precisely - that would be nice, so you can make loops that stay right on the beat when looped over and over.
Started using ASD on my Windows desktop, long before there was any such thing as Android and the only option for internet access was a 56Kbit max dial-up connection. For a guy who grew up learning songs from vinyl, it was the perfect digital solution to the analog turntable back when there was no other available consumer option. Although I'm now enjoying a 1Gbit internet connection and the latest Android device, I'm still using ASD. I use it because it works, it's easy to navigate, and simple to master. Oh, and it's never let me down. Thanks for the many years of excellence, Roni Music!
It had some issues starting a song at all, so I uninstalled and reinstalled and it works great. I use this app every day of my life because it's the only one that will pitch shift by semitones and simultaneously load up songs from Spotify. If any of you users like to listen to songs at specific frequencies like 432hz, or you want to hear a song in a different key, I think this app is the perfect one for purchase. Long time user here. Thanks, team~
