Jelly Jammer Help

A wobbly, kid-friendly music maker.

Jelly Jammer has four rooms. Tap jellies to make sound, design your own jellies, stitch them into a song, then play along with it like a game — and put your band on a spotlit stage. Here's how each room works.

A Paid app tag means that bit lives in the Jelly Jammer app for iPhone, iPad and Android. Everything else works right here in your browser.

Jam

Play notes by tapping jellies.

  • Tap the jelly pads to play notes. Each pad is a different pitch, and its letter tells you which note it is.
  • Pick which jelly to play from the strip at the top — a built-in one or any jelly you've made in the Jelly Lab.
  • Lots of jellies to scroll past? Tap the filter button at the start of the strip and choose a family, like Keys, Guitars or Special FX.
  • Simple mode uses friendly notes only, so nothing ever sounds wrong. Turn on Advanced mode in Settings to unlock the full scale with every note.

The families: Keys · Strings · Winds · Brass · Mallets · Guitars · Voice · Synth · Drums · Percussion · Special FX. The instrument jellies are modelled note by note, so a piano really rings and a flute really breathes.

Tip: Tap the big jelly on the home screen too — it plays a little tune all on its own.

Jelly Lab

Design your own sounds.

  • Tap a jelly in the strip to load it, then tap the big jelly any time to hear it.
  • Slide the controls to change the sound. Every family has its own — a piano has Hardness and Tone, a flute has Breath and Vibrato, maracas have Beads.
  • Octave moves the whole jelly lower or higher, and tells you which note it plays.
  • Give your jelly a name, an icon and a colour, then Save this jelly. Saved jellies show up in the Jam room and the Jam Factory.
  • Drums and percussion work here too, so you can build your own kick, snare or shaker.

Tip: There's no way to break it — slide things around and listen until you like what you hear.

Jam Factory

Build a whole song.

  • Pick a jelly under Jelly to place, then tap squares in the grid to switch notes on and off. Playing left to right, the song loops around and around.
  • The name at the left of each row (like C4) is its pitch. Tap it to choose a new one: an octave, a note letter, and a sharp or flat — so a song written in flats can be typed in as written.
  • Drum rows sit below the note rows: kick, snare, hi-hats, toms, congas, bongos, cowbell, cymbals, triangle, tambourine and maracas, each in its own colour.
  • Press Play to hear it, change the Speed to go slower or faster, and choose Whole song or This block.
  • Work in blocks (sections) — swipe between them, and tap the cog to rename one, change its length, or give it colour bands.
  • Swipe left to the Sequencer to arrange the order your blocks play in and how many times each one repeats. Paid app
  • The Tools row holds Erase, Sustain (hold a note longer) and Variant (flip a drum to its other sound, like an open hi-hat).
  • More note and drum rows — up to 8 of each per block. Paid app

Tip: Start with a kick on every few beats, then add a snare and a hi-hat to find a groove.

Play Along Beta

Turn your own song into a game.

  • Open it from the Play Along card on the home screen, or from Jam Factory ▸ Menu ▸ Play Along.
  • Pick a part — one of your melody jellies, or Drums. The band plays everything else while you play your part.
  • Your notes fall down the lanes. Tap the buttons as they cross the line: land it dead on for Perfect, close for Nice. Keep a run going to build a combo, and finish for stars.
  • Choose Easy, Medium or Hard to change how many buttons you're juggling.
  • Top scores are kept per difficulty, and they ride along inside the song — share it and your friends play for the same board.
  • On a computer, the F G H J keys hit the buttons left to right, so two hands can play a chord.

Tip: A song with a simple, spaced-out part makes the best first game. Easy mode is a good place to start.

The Stage

Watch your jelly band perform.

  • Tap the masks icon at the top of the Jam Factory to send your song to the Stage.
  • Your jellies play under sweeping spotlights, with the notes falling in time and the drum floor flashing on every hit.
  • Record the whole performance as a video and share it. Paid app

  • Export Audio turns your song into an audio file you can play anywhere. Paid app
  • Stuck for a starting point? Menu ▸ Example drops in a ready-made song to poke at.

Settings

Open with the gear icon on the home screen.

  • Advanced mode shows more controls for bigger kids — the full set of notes in the Jam room, and the full envelope, filter, detune and exact tempo elsewhere.
  • Studio Filter (in Advanced mode) colours everything the app plays, like putting your band in a garage or a big hall. It bakes into exported audio too.
