Bend time. Automate notes. A single grid as a multi-dimensional musical canvas — for iPad, iPhone, and Mac. Fugue Machine Rubato dives deeper into the multi-playhead piano roll concept of Fugue Machine Classic by adding time-bending playheads, parameter automation, and much more. At the heart of the sequencer is a nonlinear time engine that lets playheads move with a natural — or surreal — feel. Unlike conventional sequencers, where time advances at a constant rate, time in this engine can expressively accelerate, decelerate, freeze, and change direction. Playheads are now free to swing, strum, bounce, move elastically, and more. Built upon the time engine is a robust parameter automation system with time-bending automation playheads and envelopes sculpted with points, curves, and shapes. Nearly everything can be automated — even the notes. Eight years in the making, Fugue Machine Rubato is rock-solid and absolutely packed with features. HIGHLIGHTS • Bend time with curves, rates, and offsets • Automate notes and nearly everything else • Sculpt envelopes with curves and shapes • Position playheads anywhere on the grid • Play up to eight playheads at once • Apply note echoes per-playhead • Arpeggiate notes from multiple playheads • Blend notes from multiple playheads • Offset, stack, spread, and invert pitches • Clamp, compress, and expand velocities • Program drums via per-note Drum Trigs • Route notes to up to eight MIDI outputs • Organize patterns in nestable folders • Launch patterns quantized to the beat • Revert state via auto-saved Snapshots • Learn contextually via popovers • Explore ~150 built-in patterns • Control via touch, keyboard, and cursor • Resize Mac window at native resolution COMPATIBILITY Fugue Machine Rubato supports iPad, iPhone, Mac (Intel & Apple Silicon), Ableton Link, MIDI, and AUv3* MIDI. With the included AUv3 MIDI plugin, you can run multiple instances of Fugue Machine Rubato within AUv3 host apps — like AUM, Logic Pro for iPad, Loopy Pro, and Cubasis.

"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.

Verdict
The clearest difference is update cadence: Fugue Machine Rubato at weekly against Battalion's every 5 months. Fugue Machine Rubato also leads on rating (4.8 vs 4.6) and chart position (#109 vs unranked). Battalion's advantage is review sentiment (92% vs 75%) and iOS requirement (12.0 vs 15.6). On price, ratings volume, ads and in-app purchases there is nothing between them.
