"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.

Oscidia is an AUv3 plugin for iOS which can be loaded into your favorite DAW allowing you to use it as a sound source for any MIDI source. Its wide range of features and oscillator types allow it to produce a vast variety of sounds. In particular, the inclusion of WaveTable greatly expands the traditional wave types and brings a wealth of modulation options. Oscidia has 3 oscillators per voice, and each oscillator can be a different wavetable – all working and morphing together to create some incredibly amazing sounds. Oscidia includes SINE, SAW, SQUARE, TRIANGLE, SUPERSAW, SUPERSQUARE, WAVETABLE and ADDITIVE wave types. You can import and export compatible wavetables using drag and drop directly to the WaveTable manager. Wavetables support morphing and warping (phase distortion), all controlled by the Mod Matrix routing. The SINE and TRIANGLE wave types both support several wave folding modes which allow dramatic real-time morphing too. Oscidia also supports 5 filter types which support 12/24dB modes and morphable LP/BP/HP filter modes which can be automated from the Mod Matrix or via the Sequencer. The sequencer itself is very unique and allows up to 3 simultaneous ARPs to play at the same time. Each ARP can directly control the 3 oscillator levels independently per step, as well as the pitch, filter morph, cutoff frequency, probability, gate, note repeat and ties. This allows for some really complex rhythms to be created that are not tied to pitch. Oscidia Features: • 3 Oscillators Per Voice. • Support for Wavetable and Additive synthesis. • WaveTable supports Morph and Warp (Phase Distortion) features. • 4 LFOs Per Voice. • 5 Filter types with 12/24-bit slopes and morphable LP/BP/HP. • 4 ADSR (Attack, Decay, Sustain, Release ) or FEG (Fluid Envelope Generators). • Wave Folding is available for basic waveforms such as SINE and TRIANGLE. • OSC Sync. • XMod & Ring Mod (on osc1 & osc2). • Additive Synthesis for glass, metallic and bell like tones. • Build in Sequencer (with 3 independent ARPs). • Mod Matrix. • MPE Mode. • Internal Effects - reverb, delay, chorus, Haas, and Phaser effects. • Drag and Drop for import and export presets and wavetables. • Build in Help Manual.

Verdict
The clearest difference is price: Oscidia at $14.99 against Battalion's $39.99. Oscidia also leads on rating (5.0 vs 4.6) and update cadence (monthly vs every 5 months). Battalion's advantage is ratings volume (33 vs 11). On review sentiment, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Battalion costs $39.99 and Oscidia $14.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Oscidia holds the better App Store score, 5.0 against 4.6. Both are backed by a comparable volume of ratings — 33 and 11 respectively. Written reviews complicate that: 92% of Battalion's written reviews are positive against 88% of Oscidia's, so the app with the better star average is not the one people write more warmly about.
Battalion ships an update every 5 months, Oscidia monthly. Both last shipped on September 21, 2026.
