Before you begin

  • The library files for your intended instruments are ready.
  • Enough channels available in your current plan: 4 / 8 / 16 for Free Demo / Player / Stage and Pro.

Choosing and replacing sounds

The instrument picker organizes the available sound sources.Pixel 10a
  • Choose K Felt Upright from the instrument list.

Tap an empty channel’s instrument area to open the picker. Select a category, then a sound included in your plan. Wait for its bank to finish loading before playing. Replacing a channel’s instrument changes that channel; review its existing attributes and FX afterwards.

Factory instruments, built-in Synth presets, Sampler and imported SoundFonts are different sources. Built-in synth presets require Player; editing synth controls and importing sampler audio or SF2 libraries require Pro.

Build an overlapping layer

Overlapping ranges create a playable piano-and-pad layer.Pixel 10a
  • Tap Edit Layers before changing note ranges.
  • Read each colored bar for its layer's playable note range.

Channels accepting the same note play together. For a Free Demo example, choose K Felt Upright on one channel and Choir Pad on another. Lower the pad level and give it a softer attack or longer release if the selected sound supports envelope editing.

  1. Select an empty channel and choose K Felt Upright.
  2. Choose Choir Pad on a second channel. Leave both ranges overlapping in Layers.
  3. Play a chord and balance the second fader below the piano.
  4. Mute one channel at a time to check the contribution of each instrument; clear Mute/Solo afterwards.
  5. Save As a named preset before making another version.

Create a split range

Input controls define the inclusive range of each channel.Pixel 10a
  • Use Learn Key under Low Key, then play the note; repeat for High Key if needed.

Low Key and High Key are inclusive. A split at MIDI 60 should use High Key 59 for the lower sound and Low Key 60 for the upper sound; setting both to 60 makes that note trigger both channels.

Select a channel, open Attributes > Input, and use the Low Key/High Key steppers. Scroll the horizontal card row to reveal a control that is offscreen.

Learn Key can set a boundary from an incoming MIDI note when a real controller is connected. Manual steppers work without external hardware.

  1. Set the lower channel’s High Key to MIDI 59 (B3).
  2. Set the upper channel’s Low Key to MIDI 60 (C4).
  3. Play notes on both sides and the two boundary notes, then save the split.

Keep layers easy to identify

Name, color and mix attributes help identify a layered rig.Pixel 10a
  • Tap the instrument card's arrow to choose another source.
  • Tap the Name field to name the selected channel.

In Attributes > Settings, give each channel a short Name and Color. Voice Limit controls available polyphony; a monophonic synth lead is shown as MONO. Delete removes the channel and clears its settings, so save a copy before rebuilding a sound.

Expected result

What you should have now

You can select plan-compatible instruments, balance two layers, and make an unambiguous keyboard split.

Common problems

Both sounds play at the boundary
Low and High keys are inclusive. Put the lower High Key one semitone below the upper Low Key.
A new channel is unavailable
You may have reached the plan’s channel limit.
Notes disappear in dense chords
Check voice limits, sustain and how many layers share the same range.
