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!

Verdict

The call

The clearest difference is review sentiment: Oracle at 100% against Attack Drums's 34%. Oracle also leads on rating (5.0 vs 4.4) and price ($12.99 vs $14.99). Attack Drums's advantage is update cadence (every 2 weeks vs every 2 months) and ratings volume (23 vs 2). On ads, in-app purchases, monetization model and device support there is nothing between them.
