AGRESSIVA
Synthesizer rack
Free · In‑App Purchases
AGRESSIVA is a synthesizer rack you play with your fingers: four modules sounding at once, a touch keyboard, a four-track sequencer and a particle universe that moves with the sound.
SEVEN SYNTHESIZERS
• ENJAMBRE: dual-swarm supersaw with up to 16 saws per swarm that turn into chords.
• ÓRBITA: two-operator FM, from electric pianos to bells and basses.
• PULSO: virtual analog with sync, unison and a multimode filter.
• FORJA: physical modelling of plates, bars, bells, bowls and strings you strike, scrape or bow.
• ARSENAL: synthesized drum machine, no samples, with twelve pieces.
• SILICIO: 8-bit chip with combined waveforms, a two-model filter and chip arpeggios.
• CONSTELACIÓN: six-operator FM with three characters and .syx cartridge import.
PLAY
Touch keyboard with velocity by where you touch, HOLD, BEND and MOD, an arpeggiator and layers: each slot can play across the whole keyboard, on the lows or on the highs. In LIVE, the background blends four variations of the sound under one finger, with up to eight big knobs at hand.
MÁQUINA
Four-track sequencer with eight patterns, queue and chain, and four ways to write: steps with probability, ratchet, slide and tie; a tracker; a drum grid; and MATRIX, a grid of light with scales and three play modes.
EDIT
Every parameter in view, envelopes you draw with your finger (concave, straight or convex curves), a die to randomise and locks. 50 factory sets and 350 sounds, and your own sets and sounds in .agr files to take to another device.
MIDI
USB, network and Bluetooth MIDI keyboards and controllers, MIDI LEARN on any knob (endless knobs too), channels per slot and MIDI clock to follow or lead the tempo.
AUV3
It is also an Audio Unit instrument for Logic Pro, GarageBand, AUM and other apps: sample-accurate MIDI, knob automation, project tempo and transport, its sets as presets and one output per slot.
FREE AND FULL
Download it for free: the seven synthesizers play with their 350 sounds and the 50 sets, ENJAMBRE, PULSO and SILICIO can be edited, and MÁQUINA plays its demos. The full version, a one-time purchase for iPad and Mac (the AU too) with no subscription, unlocks editing all seven and writing in MÁQUINA.
It works offline, needs no account and collects no data. The full manual, with videos, is inside the app.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
- Computer keyboard: a strip under the on-screen keyboard shows which letter plays each key, and you can drag it to move the letters to another part of the keyboard.
- MIDI: Bank Select alongside Program Change to switch sets, and Program Change now also works inside the AUv3 instrument.
- Mac: the Help menu opens the manual.
- Full version: if you already bought it with this account on another device, it shows up by itself when you return to the app.
