ARPJAM is an arpeggio synthesizer that generates ever-evolving ambient music. Layer two independent arpeggio engines, each with its own waveform, scale, and pattern, and let the app weave an endless soundscape that shifts and breathes on its own. ■ Two Arpeggio Engines ARP A and ARP B run simultaneously, each with its own mode, scale, range, waveform, filter, and envelope. Five pattern modes: Random & Chord, Repeat, Random Single, Skank, and Drone. ■ Generative Drums A probability-based drum machine. Tune the firing density, double-hit chance, and open/closed hi-hat ratio for kick, snare, and hihat to create rhythms that evolve naturally alongside the arpeggio. ■ Sound Design Four waveforms — sine, triangle, sawtooth, square. Adjust the low-pass filter, attack, and overdrive per engine. Add depth with ping-pong delay and reverb. ■ Sync with External Instruments [NEW in v1.4] Ableton Link support — wirelessly sync tempo and bar phase with Ableton Move, Live, Koala, and other Link-enabled instruments on the same Wi-Fi network. USB-C MIDI Clock reception is also supported. Sample-accurate timing alignment, with a fine-tune Offset slider for each setup. ■ Redesigned Settings Panel [v1.4] Settings are now organized into five colored sections — Oscillator, Filter, Envelope, Algorithm, and Effects. Each section collapses individually or in bulk, and the state persists between launches. Jump directly to any section via the side rail (iPad) or sticky bar (iPhone). Clear square ON/OFF switches and vivid theme colors — orange for ARP A, lime for ARP B, cyan for Drums — make the whole panel far easier to navigate. ■ Save & Recall Four start presets (Default + SAVE 1/2/3) let you recall your favorite setups with a single tap from the start screen. Presets can be exported and imported as .arpjam files to share with other ARPJAM users. ■ Built-in Timer Choose countdown or infinite mode. The timer fades out with a gentle resolving chord — perfect as a sleep timer or as a companion to meditation. • 8 scales including pentatonic modes • 12 keys (Just Intonation / Equal Temperament switchable) • Groove control for swing feel • BPM 30–200 • English / Japanese language support • Ableton Link / MIDI Clock sync

About

Syntien 2

Read full description

Syntien 2 recognizes a variety of input sources, including touch, movement, and sound, and converts them into data for your creative work. Syntien 2 can connect to other devices and software via MIDI, OSC, and BLE. It comes with all the standard controls you'd expect -- buttons, labels, sliders, knobs, etc. -- plus a unique set of tools that go far beyond the basics. • Use an adjustable, resizable Keyboard control to send MIDI note and velocity data, in addition to pitch bend, expression, and more. • The Touch Pad control takes full advantage of your device's multi-touch capabilities. Track multiple touches independently. Use a stylus like an Apple Pencil to send highly-expressive data with pressure and tilt sensitivity. • The IMU control uses data from your device's accelerometer, gyroscope, and magnetometer to transmit your device's acceleration, rotation, or nearby magnetic field strength. • Use the Level Meter to track audio input levels, and use the Pitch Detector control to detect pitch. • Transform and scale outputs directly in Syntien 2 without any complex scripting! • Connect controls to each other using Macros. Use buttons to toggle a Keyboard's sustain pedal, set up a Slider to modulate the frequency of an LFO, and more! • Create your own interfaces and modify the behavior of controls in-app, on any iPhone or iPad, without the need for a separate desktop editor! Place and resize controls exactly how you want them using intuitive drag-and-drop gestures. • Modify controls mid-performance by sending data from your computer to Syntien. Incoming OSC messages are displayed on the screen and color-coded, so you'll know exactly what messages Syntien is receiving and whether or not they're being interpreted. Works with Ableton, Max/MSP, SuperCollider, TouchDesigner, and any MIDI- or OSC-compatible software.
