PocketMixer
A personal monitor mixer for worship teams — every musician controls their own mix from their phone.
On a worship team, everyone wants something different in their in-ears — more vocals, less drums, a click only the drummer hears — and the sound tech can’t keep up. Hardware personal-monitor systems solve this, but cost hundreds of dollars per musician.
PocketMixer does it in software. A Mac in the sound booth captures every channel from a USB audio interface and streams it over the local network; each musician builds their own stereo mix on the phone they already own.
