iACID8 vs TD3 Studio

iACID8 — Hardware roots. Pocket acid. Born from the beloved Twisted Electrons Acid8 family, iACID8 brings the Acid8 to your iPhone—built directly from the uAcid8 Slim Synth’s original firmware, with its distinctive digital grit and hands-on sequencing intact. The filter gets a serious upgrade: a modern, TB-303-inspired algorithm delivers richer resonance, more expressive squelch and extra acid bite. Crunchy oscillators feed a smoother filter and cleaner output stage, keeping the low-fi character while letting every slide and accent shine. Start with 16 factory grooves, twist your sound into shape and build your own basslines. Record notes live, add slides and accents, or chain patterns and key changes into evolving arrangements. Play standalone or load iACID8 as an AUv3 instrument in your favourite host. Each plugin instance keeps its own patterns and sound settings, with optional host transport following and independent Run control. • 12 level-balanced waveform variations with distinctive digital character • Enhanced resonant filter with envelope, decay and accent controls • 16 editable patterns with slides, swing and live recording • Pattern chaining and recorded key changes • Arpeggiator, bit crushing, wobble and performance effects • MIDI input on channel 1 for notes and sound control • Standalone app and AUv3 instrument, designed exclusively for iPhone • Warm tube-style saturation in the upper third of the volume knob • Tactile haptic feedback in standalone mode • Ableton Link for jamming with apps and devices on the same network • Life slider for live rhythmic variations without rewriting your patterns • Illustrated playing guide and printable cheat sheet Your pocket acid machine—reborn for iPhone.

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.
