Most of what happens on Jamphony happens in a room. Anyone with an Account can make one by pressing Create room, which makes them the Host. Seats are limited, and anyone else can watch.

Rooms only exist while someone's in them. When the last person leaves, the room is gone along with its chat and settings, so save a Clip first if something good happened.

The room list shows everything that's open. rooms need a passcode, and rooms are Studio rooms. To get a friend into your room, send them the room code or just the address.

Lobby

The Lobby is where you land when you open the site, and it's usually the easiest place to find people playing. It's the one room that never closes.

Its chat is shared with the #lobby channel on the Jamphony Discord. If there's a after someone's name, they're typing from Discord and can't hear you play.

Seats

You need a seat to play, so press Join to take one. Everyone without a seat is a spectator, who can hear everything and chat but can't play. A full room still lets spectators in, so you can always wait for a seat to open up.

Each seat plays one sound, and the room limits how many people can share an instrument. Variants of the same instrument count as one, so if only one player can have a sound and somebody's on Trombone Staccato, Trombone Sustain shows as taken too. If you want someone's instrument you can ask them to swap from their menu.

Some rooms need an invite from the host before you can sit. You'll know you've got one because Join glows blue.

If someone's ruining a room and the host isn't around, seated players can vote them out of their seat from the Player menu. It takes at least half of the seated players, so two people sitting alone can't vote each other out.

Private rooms

A private room needs a passcode to get in, even to watch. Jamphony makes the code for you, and everyone in the room can see it next to the room name, so anyone inside can pass it on to a friend.

Play Alone

Play Alone, in the room list, gives you the stage with nobody else on it. Studio Alone, right next to it, does the same for Studio.

Hosting

Whoever creates a room is its host. If you leave, you stay host for a while, and after that it goes to whoever's been in the room the longest.

Room settings

Room settings›Sounds›All 88 keys lets every sound play across the whole keyboard instead of stopping at its real range (see Instruments). You can ban sounds in Room settings›Sounds.

Actions

When you swap sounds with someone as host, it happens right away without asking them.

Next chord indicator

This shows everyone what chord is coming. Turn it on and hold a chord in the reserved octave, which you can move, and the whole room sees its name above the keys.

Backing tracks

A backing track is a MIDI file you play to the whole room so everyone can jam over it. Load it from Room settings›Backing track and you'll get a bar on the stage with play, pause, jump and a loop. It plays one part of the file through one sound, so the bar lets you choose which part and which sound.

The bar's menu also has speed, how hard it plays, and humanize, which loosens up the timing so it doesn't sound like a machine. Everyone else just gets a volume slider.

Bands

A band is a group of players with its own name, crest, color and chat, and it stays together after everyone logs off. You can only be in one band at a time, and you need an Account with a confirmed email.

Press to start one. As leader, you can invite people by username or from their card, and anyone can ask to join from the band's page on the Bands list. The leader can also remove members or hand the band to someone else, and a band ends when its last member leaves.

Start a jam opens a room for the band, which can be private or open. Band members can sit right away while everyone else needs an invite, and the leader is always the host. You also get a rug on the stage in the band's color.
