"A deep world to get lost in - This delivers that in spades!" - Jamie Lidell, Hanging Out With Audiophiles
Unfiltered Audio is back on iOS with its instant classic Battalion, perhaps the most advanced drum machine available on any platform. Battalion includes over 20 synthesis algorithms and 5 sampler algorithms, each built for advanced sound design via simple controls. All eight drum channels can use both samples and synthesis simultaneously. 11 filter modes and 11 distortion algorithms add further sculpting options to each voice.
Additionally, all eight drum channels contain rich modulation available for every parameter, including two LFOs, two envelopes, and more. A global Performance page shows a simplified interface that allows you to manipulate every drum channel simultaneously. Want to hear your drum beat tuned down an octave with a single knob? Done. Need a global boost to distortion or a dramatic filter gesture? Easy.
Each drum channel contains two sequencers. The first sequencer is a manual step sequencer with ratcheting, probability, velocity, pitch, micro-timing, and more... per-step! Each parameter lane can run at a different speed and length, making generative, evolving patterns a breeze. The second sequencer combines Euclidean patterns with an Unfiltered-designed permutation engine. Both sequencers run in parallel and receive further shaping via an array of Sequence Modifiers. Want one drum sequence to speed up while another slows down? The SHAPE parameter is here for you. Need that hi-hat to be a bit lazy? SHIFT will nudge it to rush or drag. And if you think drum machines have no soul, wait until you combine per-channel SWING with global HUMANIZE.
All of this advanced sound design is glued together with a flexible mixer and Unfiltered Audio's evocative effects. Battalion contains two new Unfiltered Audio effects: Shatter Delay and Headspace Reverb. Shatter Delay combines granular stretching, dynamic ducking, sample crushing, and feedback spectrum sculpting into a melange of echo bliss. Dubby, dark, dotted echoes? Chaotic glitch storms? It's all here. Headspace Reverb evolves Silo's ten classic reverb algorithms with additional filtering options. You will always find the perfect reverb for your drum mix.
Battalion includes over 150 presets to get you started. These cover a wide variety of genres and tempos, from glitch and IDM by esteemed sound designer DataBroth, to futuristic hip-hop from Willie Green (head of our favorite Backwoodz Studioz). From smoky and loose to shiny and mechanical, Battalion is ready to be your go-to solution for every rhythmic task.

Thank you for using Battalion! It has been a fun launch so far. We have a much-requested workflow improvement along with some bug fixes.
- Double-clicking (or tapping) a sequencer parameter step will reset the value to a default (i.e. pitch, velocity, ratchet).
- Fixed a crash when dragging a drum track onto the Voice/Performance button at the top of the channel selector.
- Fixed a graphical bug where the Voice/Performance button would light up when dragging a track over it, suggesting a potential drop.
- Fix for Clap engine not choking properly.
