B21 Stage Time app icon B21 Stage Time

Everything the gig needs. On stage, and after it.

Built by working musicians for the moment the lights go down and there is no second chance. Backing tracks that fire on cue, your own sampled sounds under your hands, a place to catch the song in your head, and the bookings, contracts and invoices that pay for all of it. One app, no internet required.

On stage

The part that has to work every single time. It plays your tracks, on cue, without ever making you hunt through a menu with a room watching you.

Playback you can trust

Fast, responsive transport with no lag between the decision and the sound. The controls are large, obvious and always in the same place.

Readable under any lighting

A high-contrast interface that survives a dark venue and a bright afternoon stage alike, with light and dark modes that follow the room rather than fight it.

Waveform and metering

See the shape of the track before you commit to it, with a scrubber, elapsed and remaining time, and left and right level meters running live.

Five-band equaliser

Shape the track to the room with named starting points, then fine-tune each band. Every PA is different and most of them are a surprise.

Your set, in order

Build the set list, reorder it, and know what is coming next. Track details, artwork and tempo are there at a glance so you can count the band in.

Free of clutter

No adverts, and nothing that interrupts you mid-set to sell you something. It was built for one band's own gigs, which is why it behaves itself on stage.

02

Beyond the stage

The player is where it started. The rest of the app is the rest of the job: your own sounds under your hands, somewhere to catch a song the moment it arrives, and the paperwork nobody forms a band to do.

Workstation

A workstation in your pocket

Your own sounds, played live from any MIDI controller.

  • Import SoundFont, SFZ, DecentSampler, Akai MPC, Logic EXS or simply a folder of WAV files, mapped across the keys for you
  • Performances of up to eight zones, so splits and layers land exactly where your hands do
  • Sixteen pads per performance, with a step sequencer for building patterns live
  • Record or import a sample, trim and chop it, and play it back as a kit or a tuned instrument
  • Chord helpers, an arpeggiator locked to the backing track's own tempo, and full microtuning
  • Shows put your performances in running order and step through them as the set moves
Ideas

Catch the idea before it goes

A songwriting scratchpad that runs entirely on the phone.

  • Record a sketch against a click, or just hum it, and keep the written notes beside it
  • Transcription in English, Hindi and Punjabi
  • Detect the key and the chords, tune the take to the key, and turn a melody into MIDI
  • Suggested harmony lines, basslines and chord pads to hear where it could go
  • Lyric help and a promo writer for bios, captions and booking replies
  • Powered by on-device intelligence, with a working fallback so every device can use it
Business

The business behind the band

The part nobody forms a band to do.

  • A calendar of gigs, each one a full profile: times, venue, client, fee, deposit, line-up and requirements
  • Contracts and numbered invoices generated as proper PDFs from your own act's details
  • Payment chasing that grades itself by how close the show is, and clears the moment the money lands
  • Record cash and bank transfers, or take a card payment with Tap to Pay on iPhone
  • Expenses by hand or by scanning the receipt, with mileage, per-gig costs and CSV export
  • Charts for income, paid against outstanding, and where the bookings actually come from

Card payments are provided through SumUp Payments Limited (FCA reference 900700). Tap to Pay on iPhone requires a supported iPhone and a supported payment platform. Terms apply.

03

It works when the signal does not

Venues are basements. Festivals have no bars of signal and a queue of thirty thousand people on the same mast. An app that needs the internet to play your own tracks is not a stage tool, so this one does not.

No connection needed

Playback, the workstation and your set list all run from the device. Aeroplane mode is a perfectly good stage setting.

No account to create

There is no login, no profile and no cloud service behind it. You install it and it works.

Your work stays yours

Your tracks, sounds, sketches and bookings live on your device. Back the lot up to a single file in Files or iCloud Drive whenever you want it somewhere safe.

The full detail is in the privacy policy, which is published and kept up to date on the band's own site.
