Soundbytes Introduces EST Sampling Groovebox VSTi

Soundbytes has announced the EST Sampling-Groovebox VSTi. EST is a mixture of hq-sampler and an advanced 12-row / 16-step-sequencer.

The EST-Loop-factory comes as a VSTi-plugin, supports (optionally) multi-out and works well with every VST-Host. EST will be released within the next week. Preorders are welcome for 49 EUR.

The heart of EST is a 12*multitimbral sampler. Each sampler can be controlled either by your host, midi-in or the internal step-sequencer. The step-sequencer contains 128 recallable patterns, which are clearly organized in banks, programs and variations. Each pattern contains complete sequences with triggers, notes and automation-data for the 12 samplers.


  • Imports WAV and AIF with all known sub formats
  • Uses its own 32-bit-float format for setting up slots (a sample with
  • extensions) and kits
  • Quick access via tree-menus and customizable sample-directory’s
  • One shot, forward, backward, ping pong
  • Scalable root-key
  • Multi-sample support by using multiple rows and key zones (from/to)
  • Keytrack-option
  • Sample-offset controllable
  • Up to 128 voices polyphony
  • Modes: Poly, Legato and Mono
  • Scalable Unison, Voice-Limit and Detune
  • Chord-mode (combinable with unison)
  • Morph mode (channels are used as oscillators)
  • Volume, pan and morph with inertia
  • Pitchbend (global and single) with scalable range
  • Fine-tune
  • Glide-mode (works even in poly mode) with adjustable glide-time
  • Amplitude envelope ADSR with velocity sense.
  • Modulation envelope ADSR with velocity sense (can be modulated by LFO2)
  • Two syncable LFO’s with sin, tri, pulse, saw, saw up/down and scalable phase
  • Filters (lp, hp, bp, notch, eq, hs, ls) with overdrive
  • Modulation of pitch, filter, morph and mod-adsr itself
  • Almost all parameters can be automated by the step-sequencer
  • Loop-recorder for reuse of sequences as samples or usage in other applications
  • Basic functions for mono/stereo-conversion, channel swap, normalize, gain and reverse
  • Menu option to edit and reload sample in your preferred sample-editor


  • Well structured, lightweight user-interface with customizable color-schemes
  • Visualization of used patterns
  • Step-LED’s for visual feedback
  • Integrated Help system
  • Support for right mouse button, wheel
  • Almost all functions are available without control/shift keys

Global settings and functions

  • Key-select (auto-activation of rows regarding key-zone)
  • Grid-size (piano-roll and drum-grid)
  • Record velocity, delay-time and auto-step
  • Audition (editing and sample-import, velocity and gate-time)


  • Host synchronization for tempo, transport
  • Inter process synchronization (mute, solo, play, record)
  • Relative tempo from 1/32. to 32/1t
  • Sample accurate timing
  • 3 different Sync-modes (internal, host, manual)

Row Parameters

  • Output-port (EST can use up to 12 outputs)
  • Trigger channel (active, all and 1-16)
  • Route-row (trigger other rows, make custom chords, trigger multi-samples)
  • Relative transpose, velocity, gate-time and delay
  • Swing affecting delay and velocity (scalable first step and interval)
  • Humanization for velocity, delay and gate-time
  • Step-divide, which allows to play a row in a different tempo (adjustable divide and length)

Live situation (midi-in targets)

  • Bank, program and variation recall via midi-note
  • Start/Stop, Start, Mute/Solo, Sync
  • Row-mute
  • Navigation and editing via controllers (every single step can be controlled)
  • Midi-Learn function
  • Midi-Thru
  • Panic
  • Transpose via midi-note (global and single-row)
  • Free and Hold mode


  • Step and Live recording
  • Adjustable auto-step, velocity and delay
  • Built-in Loop-Recorder, Wave-export
  • Record loop to sample

Pattern editing

  • Piano-roll and drum-grid
  • Colors can assigned to rows
  • All-rows-visible mode
  • Easy pattern editing with left/right mouse buttons
  • Cut, Copy and Paste for patterns, variations, rows and step-values
  • Undo and snapshot
  • Row rotate, reverse and random step shuffle
  • Auto-trigger, inverse and trigger-random
  • Note transpose, set to root/last note, note-random
  • Chord-progressions
  • Value increment, decrement, two value-random functions (absolute, relative)
  • All functions can optionally affect all or selected steps
  • Pattern lock (run one pattern and edit another)
  • Mouse sweeping for quick value drawing
  • Different random functions for notes, triggers and values
  • Rotate, reverse, transpose etc.
  • Data-has-changed indicator
  • Import/Export functions for banks and single patterns.
  • Tree-menus (quick access) for saved banks and patterns
  • Quick step mute/unmute
  • Magic function which produced sequences based on chords-progressions and random

Pattern structure

  • 16 variations
  • 12 trigger rows
  • Default variation (optionally), which is automatically selected on pattern change
  • Target-parameters of the 5 automation-rows

Variation structure

  • Tempo (relative to host)
  • Mode (free/hold)
  • LFO and row-subdivide restart option (never, always, on variation or pattern change)
  • First/Last step (pattern length)
  • Step-row (every single step can be muted)
  • Order-row (defines the actual play-order)
  • Break-row (enables triggering other-patterns)
  • Mute/Solo states of the trigger rows

Trigger-row structure
