Pocket BeatS, Massive Sound

Jolt was designed from the ground up to be the mobile beat station that you keep coming back to.

At its core, it’s 8 voices, each with their own step sequencer, with per-section and per-sequence parameter automation, as well as per-instrument LFOs.


Made with GRIT At
66.6761° N
12.5683° E

Six Sound Sources

Each voice can play one of 6 instruments, with a custom preset, on each step.

Each instrument also has a fully-automatable ladder-style filter, an extra noise generator, and can be assigned to a frequency band to make space in your mix.

Pitched Sampler

Classic repitching algorithm for that oldschool sampler sound.

Sliced Sampler

Slice a sample into up to 16 segments, great for breakbeats, percussion sampling, or chopped up vocals.

Sample with impunity

All samplers can record from your phone mic, resample your beats, or load in custom sample packs directly from your phone storage

Granular Sampler

Build texture out of any sample by applying granular synthesis.

Classic Synth

Classic waveforms, with spread and FM

AutoChord Synth

4 note chord synth with classic waveforms, automatically fixed to your track’s key

Modal Synth

16 sub-synths, based on Mutable Instruments Plaits, from harmonic waveforms to modelled analog drums

Classic Send FX

Multi-Tap

BPM-synced multi-tap delay with per-stage volume

Sidechain

Simple per-voice sidechain “ducking”

Reverb

A classic plate reverb algorithm with adjustable tail

Digital Delay

Crystal clear digital delay with BPM sync and feedback

A Whole Track

In your pocket


So 16 steps for one voice might include your kick drum, snare drum, hi hat, and a few reverbed sample slices. Multiply that by 8, and you’ll be surprised at the soundscapes, beats, and grooves you can build.

Finally, patterns can be chained, exported as stems or a mixdown, and you’ve got a full digital audio workstation in your pocket.
