The heart of EST is a 12*Multi-timbral 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.

Sampler

• 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).
• Oscillator mode (waveform are used as oscillators) with 2 distortion modes and lp-filter.
• 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 LFOs with sin, tri, pulse, saw, saw up/down and scalable phase.
• Filter (lp, hp, bp, br, eq, ls, hs) 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.

GUI

• 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

• Preset browser.
• Scope and level display (with clip and sync indicator).
• Gain slider.
• Songinfo (opens linked web site or document).
• Sync mode (internal, host, manual).
• 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).

Synchronization

• Host synchronization for tempo, transport.
• Inter process synchronization (mute, solo, play, record).
• Relative tempo from 1/32. to 32/1t.
• Sample accurate timing.

Row Parameters

• Output-port (EST can use up to 12 outputs).
• Trigger channel (active, all and 1-16).
• Route (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.

Recording

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