Omni: Pocket Synth is a compact, touch-first instrument for creating chords, strums, arpeggios, pads, keys, and rhythmic musical ideas with an immediate performance workflow.

Omni is designed to feel fast, musical, and expressive without turning into a complex workstation. Features: - Touch-based chord and strum performance. - Chord Voice and Strum Voice with independent sound controls. - Wavetable and subtractive / virtual analog voice engines with focused pocket controls. - Hold / latch modes for Chord and Strum performance. - Multiple strum modes including Standard, Extended, Pentatonic, Scale, and Chromatic Touchplates. - Built-in ARP with musical patterns, rate, octaves, gate, and swing. - Simple drum engine with kick and snare sequencing. - Reverb, delay, vibrato, and autopan performance effects. - Layout Editor for custom chord layouts. - MIDI In for playing from external controllers. - MIDI Out for controlling other apps, AUv3 instruments, or hardware synths. - Hold / latch performance can also be used with MIDI Out. - AUv3 Instrument support for hosts such as AUM. - Independent Chord MIDI Out and Strum MIDI Out in AUv3 hosts. - Preset Manager with factory and user presets. Omni works both as a standalone app and as an AUv3 instrument.

The free version includes the core playing experience. Omni Pro unlocks the full preset workflow, AUv3 support, advanced strum modes, Layout Editor, MIDI Out, and other creative tools.

TD3 Studio turns a MIDI file into a pattern for the Behringer TD-3 or TD-3-MO: drop a file in and the sixteen steps are cut for you, ready to edit, play and send to the device. Build a pattern from nothing too, step by step, from the on-screen keys or a MIDI keyboard plugged into your iPad or iPhone, with accents, slides, ties and rests one touch away. No TD-3 within reach? The app plays through a built-in simulator on the device's own speakers, a 303 voice of its own, so every pattern can be built and heard before the hardware ever comes out. Patterns and edits sound the same either way. One purchase covers iPhone, iPad and Mac: buy TD3 Studio once and it is yours on all three. The library lives in the Files app, under "TD3 Studio": your own patterns, the 107 TB-303 patterns from the bundled Acid-Tabs collection, and search across free online MIDI archives, all from the one panel. Open a MIDI file from Files, and it goes straight through the converter, with a timeline for picking which sixteen steps become the pattern. On iPad the whole instrument is one landscape plate: the step grid, the tone knobs, the transport and the library side by side. Below the grid sits an on-screen keyboard of one to three octaves, with accent and slide toggles and Tie and Rest buttons. Play it to edit the selected step, or press Record for 303-style step entry, one key filling one step, straight into the sequencer. On iPhone the same tools are arranged across three screens: PATTERN for the step grid and keyboard, SOUND for the simulator's tone, and DEVICE for USB or Bluetooth output and the TD-3's read and write slots. A fixed header carries file and library access and the three tabs, and a fixed transport strip below carries start, stop, tempo and the step count, so both stay in view while the middle changes. A key, Tie or Rest enters the selected step and moves to the next one, so a full pattern is sixteen taps. TD3 Studio needs a TD-3 or TD-3-MO to write or hear patterns on real hardware. On a USB-C iPad or iPhone, use Apple's USB-C to USB Adapter with the TD-3's own USB cable, or a USB-C to USB-B data cable that follows the USB-C standard (a branded USB-C printer cable; cheap ones lack the resistor that makes the phone the host and then work on a PC but not on a phone). A Lightning iPad needs an MFi Lightning to USB-B MIDI cable or Apple's Lightning to USB Camera Adapter. A Bluetooth MIDI adapter on the TD-3's MIDI IN works too. The TD-3 runs on its own power. Without the hardware, the simulator carries the whole app. TD-3 and TD-3-MO are trademarks of Music Tribe. TD3 Studio is an independent app, not affiliated with or endorsed by Music Tribe or Behringer.

Verdict

The call

The clearest difference is price: Omni at Free against TD3 Studio's $22.99. TD3 Studio's advantage is in-app purchases (none vs 1) and update cadence (every 3 days vs fortnightly). On ads, device support and iOS requirement there is nothing between them.
