Sounds Great, plays even better

Another great audiokit app. As someone who is take it or leave it with 909 sounds, I have had a blast using it and coming up with my own. The sequencer is the highlight for me though. I like being able to see where my sounds are placed in relation to one another piano roll style instead of just where all the kicks are, snares are etc. And you can also switch between 16/32 resolution! Pattern trigging is top notch as well and great for coming up with interesting grooves. If they released a sequencing app I’d buy it for sure. Hopefully they will release an 808 version of this too.

Hopefully it will get better

Based on the positive reviews I purchased this drum app - It’s not as good as the hype. Some folks even said this was the new best drum apps. I cannot fathom how anyone could come to that conclusion. It’s no where near the top of the list for good drum apps. I like the “vibe it out” and crusher options and that’s about it. This app crashes when I press the save button. It glitches out and kills all audio when I try to solo a track. There is only one drum sample to choose from. There is no ride bell, shaker, or kalimba. There’s no probability options. Limited fx options (give us a reverb and delay bus). Speaking of bussing, there’s no fx busing. No midi mapping as of yet. No randomizer. The decay setting doesn’t really matter when the samples have no sustain information unless you set the tune to 0. Even at zero it has no impact of you want a long snare note (IE: turning the sustain knob to the right is useless) Having a synth engine for bass/snare is worthless when the perimeters only expire a small fraction of the potential range. They may as well be samples for how limited the synth engine is The GUI is very rough for a paid app. Did I mention it crashes when I press save? I have immediate buyers remorse. There’s probably worse drum apps but this does not compete with any of the well known drum app options as if bows

Developer Response ,

Hello, that does sound frustrating. We have submitted a quickfix to the app store for the save error that is affecting some users. It should hopefully be there for you soon. For those reading, the reviewer is right. This app is inspired by a very specific drum machine - the synth engine and controls are very similar to a piece of hardware and $99 desktop cloud app, all for $3. For those expecting an "everything" drum machine, this is not it. It's inspired by a very specific device and sound. And the controls and sounds match that. Thank you.

I think I found a glitch

For the kick bass when I bring the drop down menu to change the volume on my iPad the decay goes up if I put the volume up on the iPad, to see this happen bring up the drop down settings of the iPad increase the volume of the iPad, get rid of the drop down menu you should hear that the decay has increased and also see it in the knob parameters the decay has gone up without ever touching the decay, if you were on the screen to see the knobs prior to switching the volume of the iPad the decay knob won’t turn but you can still hear the decay has gone up, also this app doesn’t sound like a 909 it’s a new version of 909, it’s a little bit harsher sound which is not terrible if you like hardcore techno, the pattern creation is comfortable to use very straight forward, I have a 909 and this doesn’t do it for me, its still a fun drum machine hope you guys make more we need more instruments on iPados
