Unbox tiny instruments, arrange them on your desk, and connect them to bring your space to life with sound. A story unfolds through the strangers who write to you: read their letters, answer with songs, and watch every reply shape what comes next. Get closer to the truth, one letter at a time.

Arrange instruments on your desk to create soundscapes in Musicasa. This indie simulation lets you respond to strangers' letters through music, piecing together their stories one note at a time.
About this game
Musicasa is a retro-styled music sandbox with a secret.
You've just moved into a new apartment. The desk is empty, the drawer is full, and the letters have already started arriving. A trucker needs a song to keep him awake on night rides. A couple is asking for a lullaby for their sick daughter. Someone else won't say what they need at all, but they're paying, and your contract says you must deliver.
Turn your desk into a living studio. Unbox synths, drum machines, samplers, and quirky sound toys inspired by real gear. Arrange them on your desk however you like, patch them together with cables, tweak filters and knobs, and shape each track by hand. There are no wrong notes, just experiments waiting to happen, and clients waiting to hear them.
Answer only in music. You never meet the people who write to you. You can't reply to their letters. Every song is recorded to tape, sealed in an envelope, and sent through your employer, the mysterious company that hired your services. What you send shapes your relationship with each client… and what arrives in your drawer next.
Fulfill the contract. Then ask what happens after. New commissions bring new instruments and new sounds to master. But the letters repeat themselves in strange ways, the requests circle back like a chorus, and somewhere out there, a man who speaks only in riddles seems to know why. Every song you send is heard, you are just not always sure by whom.
Game Features
Unbox & collect instruments: From retro synths to drum boxes, each with its own personality — earned one commission at a time.
Hands-on sound design: Patch devices with cables, tweak LFOs, filters, and more in real time, and hear every change as you make it.
Compose for characters: Read their letters, imagine their lives, and answer with the only voice you're allowed: music.
Record & send on tape: Perform your songs live and burn the to a cassette, seal the envelope, and mail it into the unknown.
Arrange your space: Place gear on your desk, move things around, and make the studio yours… for as long as it is yours.
Uncover the truth: Decipher riddles, notice what repeats, and learn what your music can really do.
Retro pixel art: True 320x180 pixel art and a warm, nostalgic aesthetic hiding something colder underneath.

Introducing a new gadget: "Memories"
We just wanted to share with you the latest addition to Musicasa's roaster of gadgets: Memories.Memories is both a time-synced mono delay and a chance to resurrect a distant memory. As you stretch the moments between each echo a different memory emerges, both foreign and familiar. As you deepen the delay, the recollection sharpens, and the world around you softly fades.Read full article on Community Announcements (sloppycult)
