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!
