Illustrated explanation

Two inputs, seen from your screen

C3 C4 C5

Your MIDIOther player’s MIDISofter → stronger key attack

  1. 01

    Your input · Lime

    Your own note messages appear as local input.

  2. 02

    Peer input · Orange

    The other participant’s note messages appear as remote input.

Intensity represents MIDI attack velocity, not measured microphone loudness.

This script explains the keyboard display from the viewer’s perspective. It distinguishes MIDI velocity from measured audio volume.

Written walkthrough

Play a note locally, ask the other participant to play, then compare soft and firmer attacks. Observe the colour and intensity changes.

Recording script

Local note. “On this screen, my own input is lime.”

Peer note. “The other participant appears in orange. On their screen, their own playing is local.”

Velocity contrast. “A softer and firmer key attack sends different MIDI velocity values. The display makes that contrast visible.”

Musical phrase. “The visual information helps us compare attacks, but we still listen for the musical result.”

Capture notes

Label the perspective before switching screens. Do not caption the colours as fixed teacher and student identities. Avoid describing the gradient as a calibrated decibel meter.

End card: “Two participants. Visible note attacks. Listening still matters.”
