I searched the forum, but could not find an answer that related to implementing in mindev.

I am trying to build an external which has a long-running computation. From the documentation, I tried creating a timer and calling this function using the timer. I am expecting that this function will run in the background on its on separate scheduler thread. However, the UI / Patcher gets locked up during this execution.

I have tried running on a scheduled thread and on a deferred thread. but both seem to lock up the UI. Can someone point me to an example of how to make this work?

I have defined the timer as:
timer<timer_options::deliver_on_scheduler> findGrooves{ this,
        MIN_FUNCTION{
            //This is just the definition of the timer.
            //and the link to the timer call back function
            calcCombis();
            return{};
        }
    };
and my calcCombis is a simple for-next loop to block the thread
void calcCombis() {
        m_CalcIsRunning = true;
 
        //Block the thread
        for (int i = 0; i < 1000000000000; i++) {
            int y = 0;
            y = y + i;
        };

       m_CalcIsRunning = false;
       outlet2.send("bang");

   };    
   
 I have tried defining the timer with timer_options::defer_delivery and the default empty declaration. But the result is the same.

In addition to above - I did some research and tried creating my own thread using C++ std::thread. I spin off a new worker thread to do my calculation. I have a timer to check if the thread has completed execution and when done, send out the required values from outlets.

Surprisingly, it still blocks the MAX UI. I am not sure how to debug multiple threads, however, the statement that spawns the new thread is not giving any error. Any ideas?
