Lesson 1 of 4 - Pattern Lab
Piano + Xylophone Pattern Lab
Read simple rhythms, try instruments, and build short songs.
XylophonePentatonic answer
Hear the mallet answer, then use the coral keys below to add xylophone replies.
Tap keys to build the loop.
Each square is a beat. The top label is the beat number; the bottom label is the note target. Teal keys are piano, coral keys are xylophone.
Piano
Xylo
Build a rhythm together.
Start here: tap an instrument, then tap note beats below. Each active square plays its labeled note.
Mixer + amp lab
Mixer + amp labMix the lesson like a small studio.
Each channel is generated in Web Audio, then routed through real gain, filter, drive, pan, fader, delay, compressor, and master output nodes.

Channel strip trainerShape tone, then control peaks.
Select one mixer channel, adjust low, mid, and high EQ, then set compression so the loud moments sit in the mix without chasing volume.
Automation laneDraw control movement over time.
Opens and closes the mallet melody filter so learners hear bright versus covered tone over time.
Synth + sampler patch bay
Synth + sampler patch bayRoute a sound like a real studio patch.
Pick a source, patch the route, then hear filter, envelope, LFO, delay, and amp-drive stages change the signal.

Amplifier + cabinet lab
Amplifier + cabinet labMake the speaker color the sound, not just louder.
Preamp gain, tone, cabinet filtering, room reflections, limiting, and master level all change the final sound that reaches the ear.

Choose a source and hardware path, then hear preamp gain, high-pass EQ, compression, aux ambience, pan, monitor level, and limiter protection as one routed system.

Open Cabinet + RoomCommon methodOne Knob, One Ear
Change one parameter at a time so the ear learns causality.
Koydo-built methodSignal Before Song
Teach microphones, cables, preamps, and speakers as a physical system before DAW shortcuts.
Koydo-built methodVisual Ear Loop
Pair waveform feedback with listening so production is not invisible magic.
Common methodCurve as Performance
Automation turns a control move into a repeatable musical performance over time.
Common methodTone Then Dynamics
A channel strip works best when learners first shape frequency balance, then control dynamic peaks without mistaking compression for loudness.
Common methodRights-Safe Reference Listening
Borrow general ideas such as brightness or space without copying recordings, melodies, or arrangements.
Koydo-built methodPatch Before Plugin
Learners understand modern plugins faster when they first trace source, route, modulation, and output as a signal graph.
Koydo-built methodLoud Is Not Better
Amplifier lessons should separate tone color from unsafe volume chasing.
Koydo-built methodTrace Then Turn
A learner should trace where the signal is going before changing knobs, because hardware mistakes are usually routing mistakes first.
Koydo-built methodFault Before Fix
Real studio learning improves when learners hear a broken hardware state, identify the stage, and only then apply the fix.
Koydo-built methodPlacement Before EQ
Feedback is usually an acoustic routing problem before it is an EQ problem; kids should move the microphone and speaker path before cutting frequencies.
