Oktopus User Manual

01

Getting started

Load Oktopus as an instrument in your DAW, choose a preset, then play a few notes before changing controls. This gives you a useful starting point and makes each edit easy to hear.

1
Install and scan. Run the Oktopus installer, then let your DAW scan its instrument plug-in folders.
2
Create an instrument track. Insert Oktopus on a MIDI or software-instrument track and enable monitoring.
3
Confirm MIDI and audio. Play your controller or DAW keyboard and check that the track receives MIDI and returns sound.
4
Activate when ready. Keep your Tatreal account details and product key nearby, then follow the dedicated activation guide.

First-time setup: If your DAW does not list Oktopus, rescan the instrument plug-in folder and restart the host before reinstalling.

02

Interface overview

The main window keeps the sound engines, modulation, effects, and performance tools visible as one connected instrument. Start at the voice processors, move through the pedalboard, then use the arpeggiator and sequencer to animate the result.

AVoice processors

Build and combine the source layers that form the sound.

BModulation

Apply synchronized or free-running movement to supported parameters.

CPedal FX

Shape and route each voice through modular effects.

DPerformance tools

Create note patterns with the arpeggiator and sequencer.

03

Eight independent voice processors

Oktopus provides eight voice-processing lanes. Treat each lane as a source that can contribute its own tone, tuning, level, movement, and effects to the final instrument.

Build a patch

Begin with one active processor and establish the core tone.
Add a second processor for weight, contrast, or movement.
Balance the layers before applying global processing.
Introduce additional processors only when each has a clear role.

Keep it controlled

Lower individual levels as more voices are combined.
Use contrasting registers to keep dense layers readable.
Compare the patch at low and high MIDI velocities.
Save useful starting points as new presets.

04

Sound design engines

Shape a source continuously, draw a custom vector wave, or turn imported audio into playable slices. The short demonstrations below show the intended interaction for each workflow.

Continuous morphingMove smoothly between source states to create expressive timbral changes.

Vector wave editorDesign a custom wave shape and use it as a playable source.

Sample slicingDivide imported audio into regions and turn them into a playable pattern or texture.

Sound-design tip: Make one large change at a time, then fine-tune it in context. This keeps morphing, drawing, and slicing decisions easy to compare.

05

Modulation and LFOs

Use modulation to add motion after the static sound is balanced. Sample-accurate LFOs are suited to rhythmic movement because their timing remains precise against the project.

Sample-accurate LFOsCreate repeatable, tempo-conscious movement for tone, level, and other available destinations.

1
Choose the parameter that should move.
2
Set a conservative modulation depth.
3
Choose a rate that complements the sequence or groove.
4
Increase depth only after checking the sound across several notes.

06

Modular pedal effects and routing

The pedalboard gives every voice a flexible effects path. Build the tone in stages: corrective processing first, character effects next, and spatial effects last unless the patch needs a deliberately unusual order.

Per-voice FXGive individual sources separate processing before they become one finished instrument.

Gain staging: Compare the processed and bypassed signal at similar loudness. A level-matched comparison makes tonal decisions more reliable.

07

Arpeggiator and sequencer

Use the performance section to turn held notes into grid-locked patterns. Begin with a short pattern and a clear subdivision, then add randomization or longer variations after the groove is stable.

Grid-locked arpeggiatorKeep generated notes aligned to the project while shaping rhythm and variation.

Reliable starting point

Select a simple rate.
Enter a short note pattern.
Test it against the DAW metronome.

Add variation

Extend the pattern length.
Change note order or emphasis.
Add randomization in small amounts.

08

Knob shortcuts & control features

Use these gestures to make detailed edits, change matching controls across blocks, or reset several knobs quickly.

A Precise adjustment

Hold Ctrl/Cmd or Shift while dragging a knob for finer control.

B Adjust matching knobs

Hold Alt while dragging or double-clicking a knob to adjust or reset its match in every block.

C Drag to reset

Double-click or double-tap, keep holding, then drag across knobs to reset each one to its default.

Touch devices: Modifier shortcuts require a connected keyboard. Double-tap and drag works directly by touch.

09

Workflow tips

Oktopus is most predictable when the patch is built from source to movement to effects. Save versions at meaningful milestones so experiments stay reversible.

1Source

Choose and balance the voice processors.

2Motion

Add morphing, LFOs, or sample movement.

3Effects

Route voices through the pedalboard.

4Pattern

Add the arp or sequencer last.

Before saving

Play low, middle, and high notes.
Check the patch at different velocities.
Verify that effect levels remain controlled.

Before rendering

Confirm the DAW tempo and sync settings.
Listen through the full sequence once.
Leave enough output headroom.
