Pulsar-ES is a sample-based drum machine inspired by the Estradin Pulsar. Start with 128 factory rhythms, 64 in bank A and 64 in bank B, play the eight-pad kit, and edit MIDI notes and velocities. In version 1.0.8, Random rhythm generates a new pattern in the current slot. Swing adjusts the timing from 0 to 100%. Shape the sound with filter, reverb, overdrive, delay, chorus and compression. Save edited rhythms as separate user patterns; the factory patterns remain available. Open LINK for tempo-sync settings with compatible peers. Start/stop synchronization is a separate setting. With a MIDI output selected and a compatible route configured, send pattern notes to another instrument. In a plug-in host, routing depends on the host. For iPhone and iPad: standalone app and AUv3. Hosting, MIDI and Link features require the corresponding compatible setup.

Sean's Strange Box is a polyphonic house synth with a step sequencer that jacks. Part of Time2Jack's Architect Series, it brings hands-on sound design, pattern writing and live performance to iPhone and iPad. THE SOUND Two oscillators with SHAPE, DEFORM and SYMMETRY, a sub and noise, and up to four-voice UNISON with DETUNE and stereo SPREAD. Shape the sound with LP12, LP24, high-pass and band-pass filters, two ADSR envelopes and three LFOs, including Lorenz and Rössler chaos. A twelve-slot modulation matrix connects the LFOs, envelope, velocity, XY pad, pressure and tilt to your sound. Chorus, phaser, ping-pong delay, reverb and a three-band EQ run in the order you choose. Sixteen-voice polyphony. STRANGE AND BENT STRANGE moves from subtle instability, filter motion and stereo drift into deformation, deeper modulation, effects movement and rhythmic variation. BENT focuses on timbre. Variations evolve every bar, and the same gesture produces a repeatable performance. FREEZE and REPEAT add momentary delay and rhythmic effects. THE SEQUENCER Build patterns up to 64 steps long with velocity, accent, probability, ratchets, ties and slides. Put up to five notes on a step, or let CHORDS generate a progression in your key and scale. Record four automation lanes. Eight scenes, A to H, change on the bar line, and CHAIN plays them in the order you choose. GENERATE offers a new house bassline when you need a starting point. JAM AND PERFORM JAM gives you a note matrix, two octaves of keys, a metronome and recording into the sequencer. Lock your key and scale to stay in tune. PERFORM brings the XY pad, macros and effects together for live playing. EZ AND PRO Two control surfaces share the same instrument. EZ groups sound design into SOURCE, TONE, SHAPE, MOTION and SOUND, plus STRANGE. PRO opens the full set of controls. Switching surfaces preserves your sound, pattern and playback. 58 FACTORY SOUNDS Explore house basses, acoustic-inspired instruments, unison and chaos sounds. Search, tag and audition presets, or HYBRIDIZE two sounds into something new. PLAY TOGETHER Use Ableton Link, DJ SYNC and MIDI input to play in time with other gear. MIDI Learn connects controls to your controller. The included AUv3 instrument runs in compatible iPad music hosts. Save a complete sound, modulation matrix and all eight scenes in a .strange project. Runs on iPhone and iPad. No account, subscription, ads or in-app purchases. Make music offline; enable local-network sync when you want to play together.
