Fitting Audio Item to Tempo Map

Getting Stuff Done How do I .... ?
#22

You could do that via OSC (enable Preferences > Control Surfaces > Open Sound Control) e.g.

oscsend osc.udp://localhost:3819 /access_action s Editor/script-action-1

for Ardour 6 and later this will be

oscsend osc.udp://localhost:3819 /access_action s LuaAction/script-action-1

Ardour 6 has 32 numerically indexed bindable script-action and 12 assignable buttons (Ardour 5.x offers 8).

Can I use

dofile("another script.lua")

any way to get a new line in the prompt for radios ?

No. Scripts are supposed to be self-contained and portable with a session to any other machine. Relying on external files or libs would break that.

How about using a dropdown instead?

I don’t think there’s too much hope as this is not working on the main menu

WinMenuSelectItem, ahk_class gdkWindowToplevel , , Session, Open...

Sorry I did’nt realize you can only have 9 scripts in Edit > Lua Scripts because you only have 8 buttons unless you run it from the scripting window (unless I have missed something ?) . It’s all looking a bit difficult to implement things, tho the potential is there. In REAPER I can have 1000+ scripts and call on any of them from within other scripts.
Maybe I’m missing something, will have another look tomorrow.

How did you determine the key frame map?

#28

You can have unlimited scripts (Window > Scripting), but you can only assign a limited amount of them to keyboard-shortcuts or to dedicated Actions.

(Session scripts, callbacks or DSP scripts are only limited by CPU power, but that’s not relevant here)

If you have a tempo map you get the samples in the TempoMap section in the project xml.
Depending on what sample rate you are using you can calculate the samples/frames at a bar or beat, in the map you have the current sample > 441000‬ and target > 420646 will change 120bpm to 130bpm

0 0 (120 bpm)
176400 176400 (130 bpm)
441000‬ 420646 (100 bpm) 
617400‬ 632326 (120 bpm)
3131100‬ 3146026‬ (110 bpm)

In Ardour/git (upcoming Ardour 6) you can get this information with

The harder part is to map the beat-position of the file to ardour’s map. It’s mostly rule of three with incremental offsets to the previous sync point (except Ardour also supports temp-ramps so this can get complicated).
