Description

SAM, the 1982 speech synthesizer, sings "One and Only" by rai1367, with a 3D wireframe music video.

It's all made on the watch as it plays: SAM's voice (lead and harmony), the bass and the keys are synthesized live, and the drums are played from six tiny drum hits. Nothing is streamed from your phone. A 3D wireframe music video plays along, timed to the music:

- Karaoke lyrics, word by word, as text or as 3D wireframe letters
- Scenes that change with each part of the song, pulsing to the kick drum and bass
- A robot that lip-syncs to SAM's singing
- Effects set off by the lyrics, including a cameo from the Index 01 ring
- A wireframe Pebble Time 2, made from Core Devices' own CAD models

Controls:
- The song starts when the app opens
- UP / DOWN: volume, in 10% steps
- SELECT: backlight on/off (after the song: play it again)
- Hold SELECT: lyrics as text or 3D wireframe letters

I didn't port over every note, I just got it sounding 'good enough'.

Needs a watch with a speaker: Pebble Time 2 only.
