Macro For Sequencing Setup

Programming and Development Macros and Scripting
1

I use audacity for sequencing.

My setup is

  1. turn on snap to nearest
  2. Generate Rhythm Track based on my criteria
  3. Analyze - beat finder with defaults
  4. drag the beat finder ‘beat’ to the nearest snapping position (to the left)

From there I align my tracks with the beats.

I’ve figured out how to do 1 and 3 with a macro.
How can I open the generate rhyhtm track dialog via macro/script?
How can I move the beat finder track to the nearest snapping position?

You can’t. Audacity’s Macros are just a simple list of instructions. When a Macro sends a command to run the Rhythm Track plug-in, it can include the required parameters (settings) for the effect, or else the effect runs with default settings. You can’t change that on the fly in a normal Macro.

For more advanced scripting, you need to use a language that is more flexible than just a list of commands. Audacity provides two options:
Nyquist Macros: Nyquist-Macros - Audacity Manual
Python scripting: Scripting - Audacity Manual

Thanks, I got a pretty functional solution using only Macros. Strongly inspired by Demonic Sweaters on youtube https://www.youtube.com/watch?v=Iyio2jEPYOk

Gonna leave this here for anyone that stumbles on this thread in the future. Note, you have to edit the macro to tweak the RhythmTrack options.

RhythmTrack:bars="120" click-track-dur="0" click-type="Metronome" high="84" low="80" offset="0" swing="0" tempo="30" timesig="4"
SetTrack:Name="click"
BeatFinder:thresval="65"
SelectTracks:Mode="Set" Track="1"
SetTrack:Name="beat"
SelectTime:End="0" Start="0"
SelectTime:End="0.017" Start="0"
