Tap tempo

Tap the tempo for rhythmic automation

TapTempo feature steps :

1. Draft specifications
2. Draft implementation
3. Stable spec
4. Stable implementation

Draft specifications

How to define the tempo ?

• Client side : with a tap button on user interface (manually)
  • three/four hits and calc average then send VIMS_TEMPO_BPM
• Server side : based on sound peak VIMS_TEMPO_SOUND_PEAK (ui to select "sound peak tempo") - Why not bpm detection? : (pro) peak based could start without delay , (pro) seems to be faster (less cpu cycles) than bpm detection. (con) ???
  • selection between low, high, med fi
• drawing the tempo (sound or manually based) has fx anim curve
• start / stop / pause the automation.

How to choose what will be automated ?

• Like MIDI learning ?
• Widget Click + Modifier ?
• VIMS edit list ?

What could be automated ?

• fx activation (enable/disable)
• fx parameter value - bound could be defined
• vims / vims bundle ?
• macro slot

Draft implementation

You can see progress in : https://github.com/d-j-a-y/veejay/tree/djay_fxtap

More definition to come and any idea welcome !

Rename panel "FX Loop" to "Tempo Tap"

How about a simpler solution ?

1. You tap a button in the UI a few times
2. Calculate the average time between taps
3. Allow the user to send a bundle of VIMS messages to the server periodically using sayVIMS
   3.1 The time between VIMS messages is the average time

VIMS bundles:
Just a text blob containing VIMS messages

3. Allow the user to send a bundle of VIMS messages to the server periodically using sayVIMS

Why not create let say 'tempo engine' server side ? and user vims to create/delete, start/stop/resume new tempo related jobs?
