ESQ is a Max For Live MIDI tool designed for generation and advanced manipulation of patterns and beats.
ESQ is based on several sound synthesis techniques, adapted to a standard step sequencer to deliver incredible new flexibility.
Basically a 6 tracks sequencer, ESQ can control and trigger up to 12 (!) different notes.


ESQ is composed of two sections: the device itself, and the external window.
ESQ is designed for you can focus on writing sequences in the external window as first step, then deeply twist them with the parameters you get in the device. Once you wrote your sequences, you can close the external window and go wild on device parameters for a journey through unexplored sequencing territories.

In the external window you'll find all tools that you are already comfortable with, if you usually work with step sequencers for beat making: an unique step sequencer lets you handle velocity, chance, and relative delay for each step. You can set exclusive number of steps for each tracks, all tracks maintaining always the same length. Then advanced random functions (the K-Devices way), copy and paste, the chance to trig up to 2 notes and edit up to 2 sequences per track, will let you work faster and get complex results, when you need them.

When you got a nice pattern, you can close the external window. The device itself offers a nice visual feedback of your sequences, and you'll find here a series of unusual tools to process exclusively each track: moving steps, shifting and creating accents, introducing breaks, deeply controlling the time.

Enjoy beats you never even dreamed of.

Audio Demo



It's a phase! - ESQ sequences are audio-driven, so you can manipulate them in innovative ways, thanks to like-audio processors: bend, squeeze, warp, and more.

One step, multiple parameters! - Set velocity, chance, and relative delay for each step; easily edit and keep an eye on all values thanks to multiple view in this step sequencer exclusively designed for ESQ.

Copy / Paste - Move perfect sequences from a track to another thanks to copy and paste buttons.

Time flexibility - Once you set a global length, you can set exclusive ratio and number of steps for each track: welcome intricate patterns à la carte.

Drag them all! - Use drag function to smoothly scale the whole sequence with your mouse.

6 tracks -> 12 notes - Each track can trigger up to 2 notes, thanks to random probability rules.

Multiple sequences - Play and edit up to two sequences per track. Select track by hand, automation, or random. With chance parameter, this opens doors for infinite variations and generative music.

Global controlled random - Set your values for velocity, chance, and relative delay, check tracks you want global random affects, and hit the button to get instant coolness.

Hierarchized time resolution - All sequences phases depend on the main one. It's fun to automate global or local ratios for time fluctuations, to get back in sync when you want! All sequences will keep the same length, so to play with local ratios also introduces unexpected breaks, allowing to play your sequences for example one time and half, then start again.

OOG Series

ESQ is part of OOG series!!
OOG tools are designed to write music and control instruments and effects with a different approach and new features.
Starting as a familiar kind of tools (basically step sequencers), these devices go beyond the classic functions.
Being their engines audio-driven, OOG devices bring sound synthesis and processingtechniques (as sync, phase distortion, etc) to modulation and MIDI sequences manipulation, opening to new exciting perspectives.

These are killer devices for users that want to go wild with time signatures, complex time, micro articulation, odd grooves, IDM and experimental music; but they are also so versatile and easy to handle! They will become the best partners also for users looking for catchy bass lines, straight beats, and groovy modulations.
