How saving works
Turn your current SYNTH settings into a new WAV sample in My Library. Your original sound stays untouched. Saves one C4 note with the current filter, envelope, movement and effects. For loops, exports a 2-second note.
New sounds appear in MY LIBRARY and can be selected as another SYNTH source. Existing CREATE WAV downloads are unchanged.πΉ MIDI KEYBOARD

Privacy & storage
Saved sounds and Recorder projects stay in this browser profile on this device. The app does not upload recordings. Browser data can be cleared or evicted; private browsing may discard it. Export sample packs and use the Schools backup before closing or changing devices. Old local-file and other web addresses have separate storage; restore an exported backup to move work here.
Ask permission before recording another person's voice. Children should use this with appropriate adult guidance.
π« SOUND SPARKS FOR SCHOOLS
Keep creating after the workshop! Make a sound, shape it into an instrument, save it, then take your project to another computer.

Existing sounds are never replaced. Privacy: this file includes WAV audio (which may contain voices) and is not encrypted. Store and share it securely.
Your library stays on this device unless you choose to export it.

π©βπ« TEACHER CORNER
Three short classroom activities, with no accounts or uploads:
- Sound hunt (15 min): record five safe sounds; discuss what makes each recognisable.
- Build an instrument (20 min): choose a sound and explore pitch, filter and envelopes on SYNTH.
- Sound story (20 min): create a collection of five sounds that tells a story; export the pack and share it locally with your teacher.
Safety: ask permission before recording voices. Do not put children's names or personal information in sound names or backups. Exported projects contain audio, so handle them according to your school's safeguarding and data policies.
