XZZZX

Overview:

XZZZX is a MIDI-controlled video player with timecode display.

I had a very simple need: Use my Teenage Engineering OP-1 and OP-XY to control playback of :30/:60/:90 second social media videos on my iPhone, with a timecode display, for composing and scoring music.

Existing apps are heavy, had a ton of features I didn't want or need, and were all overkill for this simple task. I just wanted to control a video via PLAY/STOP/CONTINUE sent from my synth with a timecode to understand timing.

XZZZX does this simply and easily, because that's all it does.

Features:

• FREE
• Responds by default to System Transport messages: play, stop, and continue (with SPP)
• Supports MIDI CC control of start/stop/continue and video mute/unmute via custom configuration
• Timecode display
• Auto BPM detection from MIDI clock
• Hybrid clock sync (timecode corrects to MIDI clock every beat)
• Use app with a saved video or no video
• Loads video files locally. Takes a bit longer to start up, but no privacy concerns and it works offline.
• Configurable play and paused timecode colors
• Configurable video muted and unmuted colors
• MIDI connection selection, memory, and state detection
• Connect directly via cable, Bluetooth, or use a Mac as a wireless MIDI hub
• Auto/Light/Dark appearances
• Works on Apple Silicon Macs, too!
• Works with any MIDI-compatible synth, DAW, sequencer, or software
• Works great with my MIDI Transporter Mac app

Notes:

• Need a stand for your OP and have a 3D-printer? Check out my OP stand on MakerWorld.
• While XZZZX's timecode corrects to MIDI clock every beat, it doesn't attempt to keep the video in sync with the device that sends the start/continue command.

  Once you send a command, the video free-plays. The video will eventually drift and get out of sync with your device(s), but it's negligible for very short social media videos.

  I could invest time developing an algorithm to keep the video in sync, or I can use the video as the MIDI timing reference, but it's not really what I set out to do with this app.

  Let me know if that's something you're interested in seeing.
