At the moment you can't do it with actors*
*Note you could pause the engine using a Pythoner actor to perform the keyboard shortcut for you, but then it won't be able to un-pause the engine because it's an actor and actors don't operate while the engine is paused.
What I'd do is put a Comment in the Control Panel listing the Keyboard Shortcut for yourself or your operator:
Pause Engine/Unpause Engine on macOS = Cmd+Shift+P
Pause/Unpause Engine on Windows = Ctrl+Shift+P
Hello everyone, I need to insert a button in the controls that makes me "pause engine" how can I do it?

@panicoescenico Hello, did you test two different TH2G on your M1 Max and did it work? What was your experience? I also want to connect two TH2G DE and DP to my M1 Max Macbook. I hope it works . Thank you!!!

Also I just noticed in your screenshot you should have your Real Time Watcher connected to a Tap Tempo actor. The way you’ve got it set up the first trigger will just start the Timer actor because triggering the ‘run’ input on a Timer actor more than once doesn’t do anything.

Likely because the add-ons page is a separate account from the forum.
Thanks for sharing! <3

Ah, yes those user actors are for Isadora 4. I’ll go grab the Isadora 3 ones for you, one second.
@woland I created a Global User Actor Folder and attempted to drag the hold-range-and-scale.iua4 file from the Finder into the Scene Editor of my open Isadora document, and neither worked. I'm on a MacBook Pro with an M2 Max Chip, 64 GB of Memory, running Sequoia 15.5. My Isadora is 3.2.6.

In the screenshot your value coming into the Limit-Scale Value actor is lower than the ‘limit min’ on that actor’s first input, so nothing is coming out.
More specifically, you told the Limit-Scale Value actor to scale incoming values between 40 and 180 to outgoing values of 0 to 127, but your incoming value in the screenshot is 0.1661, which is well below 40.
Use the Hold Range and Scale User Actor I provided in my first comment to get the range of values and automatically scale them.

Re: [Using Heart Rate MIDI Data to Control Volume in Isadora](/topic/9236/using-heart-rate-midi-data-to-control-volume-in-isadora)
I just found out that the app (Movesense), which is connected from my iPhone, is receiving MIDI as a clock and needs to be converted to bpm. Here is what I have tried unsuccessfully.
Real Time Watcher to timer. Calculator A – 60 ÷ seconds → ticks-per-minute. Calculator B – ticks-per-minute ÷ 24 → BPM (HR). A Limit-Scale Value – maps 40-180 BPM to the full CC range 0-127. A Smoother, and a Send Control – sends CC 21 on channel 1 via “Isadora to Ableton Live” (I renamed my IAC Driver).
The signal stops at the Limit-Scale Value and doesn't send an output signal to the smoother, and in turn, the send control.
Any thoughts or ideas to remedy this?
