909 Customer Insights

1. Kick drum asideit sounds fine and has some good options such as individual volumes and changing the number of bars and stuff but you can't swing it and therefore you can't really make a good beat.

2. Regardless of the lag it's still awesome fun to play with! A few tweaks and this could be the best damn 909 emulator there is!Its too bad because the interface is dead easy but theres no way to export tracks and the the rhythm engine is pretty beat.. falls off sync with just a few hits on a beat and no swing function.

3. Developer is an as***le, or a retard! DONT USE THIS APPAbsolutely Fabulous !! Not sure what all the Moaning Minnies here are on about with the timing but I've got a Samsung Galaxy S9 plus and this works PERFECTLY ! NO SHADOW OF A DOUBT ! No ads, No permissions just The BEAT with The Buzz ! Music IS Life \m/ Way to Go Dev with GratitudeGreat little app to sketch out rhythms on the go.

4. Little choppy in the timing, and a bit disappointed by the lack of a shuffle/swing function, but for what it is, I love it! The samples are clean, but I can't tell if my tablet is just laggy or the samples aren't cleanly cut, as there is some audio lag, especially when playing certain large patterns such as "Revolution 909" and that.

5. Works well, filter would be good a addition.Probably one of the most easy to use sequencer apps that I have found here.

6. Can't play individual bars.. A real problem if you are working on something more than a few pages long, if you want to listen to the 18th bar, you'd have to listen to the whole lot to get to that 18 page/bar.

7. maybe invlude accent for samples, the volume faders would work really great with that.Garbage. Stripped down no nonsense 909 sequencer.

8. A little bit disappointing, cuz this could have been something really good.Very easy to use, just needs to have midi sync.

9. Finish the app, add the features that any emulator worth its salt can DEFINE ITSELF By and I'd probably give this a good grade.

10. Spent a couple hours making a beat to find that there's NO WAY TO EXPORT FOR USE.

11. musically its rather limitedI can't even figure out how to change the drum sounds.
