Swell60 Drone60

Swell is how far the drone ebbs on each exhale. Cues are soft tones in your key: octave to breathe in, fifth to hold, root to breathe out.

Tuning

Cents

B♭ is for trumpet, clarinet and tenor sax, E♭ for alto and baritone sax, F for horn. Note names follow your instrument; the drone plays at concert pitch. Tuning moves the lines and the drone together.

Microphone

Headphones help: through the speaker, the drone reaches the microphone too and can hide quiet notes.

A slow swell in level and brightness, each wave a little different, like surf. Depth is how far it ebbs between waves.

Harmonic Systems

No takes yet. Tap ● Rec to record along with the groove, the breath or the drone. Takes stay on this phone.

Microphone

BackTrack records with the phone's own mic, so AirPods don't switch to call quality. While the mic is on, iPhone may still play the backing from its own speaker; that routing is up to Safari. Automatic uses the AirPods' mic instead.

Sync …

Measure with the phone speaker in a quiet room: BackTrack plays eight clicks and listens for them. Over Bluetooth, use each take's Sync slider instead.

Takes live in this app. Each Home Screen shortcut keeps its own, and removing a shortcut removes its takes, so share the ones you want to keep.

History

Sessions longer than 20 seconds show up here.

BackTrack uses the microphone only while you record, tune, measure sync or find mics, never at any other time.
Tune draws your pitch while the circle runs. Nothing is recorded unless you tap ● Rec. Slides, wobbles and vibrato are all welcome, and there's no score.
Headphones help. Through the speaker, the drone reaches the microphone too, so quiet notes may not show.
Takes stay in this app on this phone. Nothing is uploaded. Share any take you want to keep: removing BackTrack from your Home Screen removes its takes.
For the tightest timing, use the phone speaker or wired headphones. Over Bluetooth you can slide a take into sync afterwards.
