Attack Drums is a synthesizer designed mainly for drum sounds, but the powerful sound engine can also be used for everything else - including vocals. Based on the Waldorf Attack VST PlugIn from 2001, it consists of a 24-part sound engine, now packed with a pattern sequencer and a versatile effects section.

One highlight of the effects section is the new Phrase Vocoder, a vocoder that uses written text instead of spoken words. Lyrics in - song out, adjust gender as you have always wanted!

Just like Waldorf Nave, Attack Drums is a seriously in-depth musical instrument - easy and fun to use, but a sonic beast at its core!

Please add Ableton Link 😎👍

I LOVE this app, but really wish it would sync better with other apps. The MIDI clock isn’t cutting it and even with an app like MIDILinkSync i still notice lag that can’t be fixed in any way. This is such a wonderful drum app, but it would be so much better if it would sync better with the rest of my apps. Ableton Link would most definitely be the key and it would make this app so much more useful for the majority of iOS musicians.

Still 5 stars to let the developer/support know there are still fans out there of this app. Don’t be demotivated by the few haters in this review section. Keep ATTACK alive please with some long awaited updates. This app has such incredible potential still and with a few tweaks could become just as much of a must-have as Nave is! 😁👍👍

Promising design! Few gripes, mostly praise

On iPad pro this thing rocks out!

I want each pattern to be up to 64 steps...

Is there a way to assign separate outputs in iOS? If so I wish this thing allowed for it in apps like AUM or Cubasis.

This is what iOS needed. My go to for drum sounds and grooves. I think this thing is very accessible. The workflow is quite straightforward and all parameters are laid out well.

I'm a Waldorf fanboy I'll admit. Everything can be improved upon is my mantra, however. This one is no different. Only 16 steps per pattern is quite a limitation in my opinion. If it must remain this way, I would like to set the loop and then have independent navigation between patterns that are within the loop. It's too hard to write in the current pattern before it shifts to the next one which is the only way to write multi-pattern loops. This is a shame because the sound engine is so nice!

Still gets high rating! Perfect for analog style drums or sample slices or one shot samples... The sky is the limit. Like I said iOS needed this.

But hey Waldorf, where is the Dropbox integration? I want to email my buddy everything in a project file, etc. we need accessibility please! iTunes won't cut it.

Stoked at First, Disappointed at Last

Pros: it's a 24-voice/48 oscillator monster synth that's great for drum creation. The internal sequencer is pretty good, and the effects are fun.

Cons: It doesn't play well with other apps. I spend about 20 hours trying to incorporate Attack with Modstep, Cubasis, and AUM. I've never been so frustrated at software before. MIDI response and routing are inconsistent as it gets, and when I can get it to communicated with other apps, eventually it breaks down like a teenager who wears too much eyeliner and listens to The Cure. Heck, even bouncing samples out of it is a pain. There's so much potential here, that it's a shame to toss it into the rubbish bin, but $20 is the least valuable thing I wasted on this.
