Elastic OSC is a synthesizer app based on the DSP code of the Mutable Instruments Plaits hardware oscillator module, one of the most beloved (and cloned) oscillator modules in the Eurorack modular scene! Like the original, Elastic OSC comes with a wide variety of possible sounds, from analog-style, FM, and additive sounds to physical modeling, percussive, and even drum sounds. Elastic OSC can be used in both monophonic and 8-voice polyphonic modes. You can play the app using the (on-screen) keyboard or an external keyboard or sequencer inside your DAW of choice. The app focuses on ease of use, featuring two XY pads for intuitive sound manipulation of the OSC engine and the effects. Despite the simplicity of the cleaned-up interface, the sound possibilities are vast – thanks to 24 different oscillator models and the ability to automate parameter changes, as it is possible in all Elastic apps released so far. A versatile Arpeggiator makes it easy to start with simple ideas or can already create entire sonic worlds. Elastic OSC includes an integrated help system (tap “?”) to provide explanations for nearly every GUI element, the underlying DSP model, and most of the app’s functionality. CDM: "Elastic OSC becomes a must on iOS. It’s fun to use as an instrument in your iPad DAW of choice." SYNTH ANATOMY: "Takes the Mutable Instruments (Plaits) algorithms on a wild trip. A nearly perfect app." ROBERT LIPPOK: "Elastic OSC is incredibly fun to work with from the very first minute. The GUI is really well thought out and has 24 integrated synthesis models, as well as the ability to load DX7 sound banks. Omg, so good." --- FEATURES --- SYNTHESIZER – 24 different Sound Engines from MI Plaits DSP code – 4 main parameters per synth engine (Frequency, Harmonics, Morph, Harmo) – Recordable Modulations/Automations for almost all Parameters with a length of 1, 2 or 4 beats. – ADSR Envelope for Amplifier – LPG Envelope for Modulations of Timbre, FM, Harmonics – Adjustable Velocity effect on Volume and/or LPG Modulation – DX7 Bank and Wavetable Import ARPEGGIATOR With different Arp Modes, Rates, Octave Ranges and Skip Notes functionality MASTER FX – 5 effects (5 different Overdrive/Distortions, Hi-Low-Filter, Chorus/Flanger, Delay, Reverb) – Automations for all effects parameters – Master Gain and switchable Limiter effect SYNTH ENGINES - Virtual Analog - Waveshaping - 2 OP FM - Granular Formant - Additive - Wavetable - Chords - Speech - Granular Cloud - Filtered Noise - Particle Noise - String Model - Modal Resonator - Bass Drum - Snare Drum - Hi-Hat - Virt.

LFO MODULATION TARGETS • Frequency Amount • Timbre Amount • Morph Amount • Harmonics Amount • Filter Amount • Pan Amount LFO MIX The MIX view enables you to blend multiple LFOs and define how strongly each active LFO influences a target parameter. The closer a target is placed to an LFO corner, the stronger its influence. All active LFOs always sum up to 100% (e.g. LFO1 50%, LFO2 30%, LFO3 20%).

About

TD3 Studio

This application converts MIDI files into patterns for the Behringer TD-3 or TD-3-MO synthesizer. It allows users to build and edit patterns step-by-step, with or without the physical hardware, using an on-screen keyboard and simulator.

Highlights
  • MIDI file to pattern conversion
  • Step-by-step pattern building
  • On-screen keyboard and MIDI input
  • Built-in TD-3 simulator
  • Accents, slides, ties, and rests editing
  • Library management via Files app
  • Cross-platform compatibility (iPhone, iPad, Mac)

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: Elastic OSC at $14.99 against TD3 Studio's $22.99. Elastic OSC also leads on iOS requirement (12.0 vs 17.0). TD3 Studio's advantage is in-app purchases (none vs 2) and update cadence (every 3 days vs fortnightly). On review sentiment, ads, monetization model and device support there is nothing between them.
