What this dot point is asking
Edexcel wants you to use the DAW as both instrument and studio for a technology-based composition: working with MIDI and audio tracks, virtual instruments and plug-ins, the piano roll and arrangement view, loops and automation, and routing and effects, to assemble a whole piece in software. Fluency with the DAW underpins Components 1, 2 and 4, and how its features support composing is examined in Component 2.
The answer
Tracks: MIDI and audio
The MIDI-versus-audio distinction governs how each part is created and edited, and the freedom of MIDI is central to composing in the DAW.
Virtual instruments and plug-ins
The piano roll, loops and arrangement view
These views let you compose visually and structurally, building and reshaping a piece directly on screen.
Automation, routing and effects
Examples in context
When a composition is built from programmed virtual instruments, sampled loops and automated effects entirely in software, the DAW is serving as the whole studio. When a part is edited note by note in the piano roll, the DAW's editing power is at work. When sections are copied, moved and reshaped on the timeline, the arrangement view is structuring the piece. The DAW is the single environment in which a technology-based composition is conceived, developed and produced.

Q1. State the difference between a MIDI track and an audio track. [2 marks]
- Cue. A MIDI track holds editable performance data driving an instrument; an audio track holds a recorded waveform.
Q2. What does the piano roll let you do? [1 mark]
- Cue. Enter and edit MIDI notes precisely (pitch, timing, length, velocity) on a grid.
Q3. Give one advantage of virtual instruments when composing. [1 mark]
- Cue. A wide range of sounds in software with editable, recallable MIDI control (any valid one).

Edexcel 9MT0/02 20214 marksExplain the difference between a MIDI track and an audio track in a DAW, and state one advantage of working with virtual instruments when composing.Show worked answer →
A MIDI track holds performance data (note, velocity, controller messages) that triggers a virtual instrument or hardware to produce sound; it contains no audio of its own and is fully editable, so notes, timing and the instrument can all be changed after recording. An audio track holds recorded audio (a waveform), the actual sound captured by sampling, which is edited as audio (cut, fade, process) rather than as note data.
One advantage of virtual instruments (software synths and samplers) when composing: a huge range of sounds is available within the DAW without any external hardware, and because they are driven by editable MIDI you can change the notes, the performance and even the instrument at any time, experiment freely, and recall everything exactly. (Other valid advantages: low cost, total recall, easy layering, integration with the project.)
Markers reward MIDI track = editable performance data driving an instrument, audio track = recorded waveform, and a genuine advantage of virtual instruments (range of sounds in software, editability, recall, low cost).
Edexcel 9MT0/02 20234 marksDescribe how the features of a DAW (such as the piano roll, loops and automation) support the process of composing a technology-based piece.Show worked answer →
The DAW provides the tools to build a whole composition in software. The piano roll (a grid showing MIDI notes against pitch and time) lets you enter, see and edit melodies, chords and drum patterns precisely, adjusting pitch, timing, length and velocity, which makes composing and refining parts easy without traditional notation. Loops let you build and repeat sections of material and audition ideas quickly, and you can layer and arrange loops in the arrangement view to assemble the structure. Automation records changes to parameters (volume, pan, filter, effects) over time, so the music can evolve, building energy or opening up sections, which is central to developing a technology-based piece.
The arrangement view ties it together, letting you lay out sections, copy and move material, and see the whole form. Together these features let you compose, develop, arrange and produce entirely within the DAW.
Markers reward the piano roll for entering/editing MIDI parts, loops for building and auditioning material, automation for evolving parameters over time, and the arrangement view for assembling the structure, all supporting composing in software.
