CPU overload when turning the attack knob

Reylon

Hi guys, my CPU screams when I'm turning the attack knob. The knob is assigned to 1470 groups but that should not be a thing why the CPU overloads...

on ui_control($Caroseria_ADSR_Attack)
    $group_counter:=1
    while($group_counter < $NUM_GROUPS)
    set_engine_par($ENGINE_PAR_ATTACK,$Caroseria_ADSR_Attack,$group_counter,0,-1)
    inc($group_counter)
    end while
end on

That is exactly why it overloads. You should only update groups that are loaded/unpurged/are making any sound. Then when you change soundsources, transfer the relevant engine parameters to the newly selected group(s). This is how you save a lot of CPU.

Thanks ED,

I was browsing the forum and found a script.

with some adjustments...

Just add purge_group($menu2,1) to $menu_1's ui_control callback, and the other way around, purge_group($menu1,1)to $menu_2's ui_control callback. Also, make sure that menu entry values for group 3 and 4 are 2 and 3, not 0 and 1.

Might this do it?

on init

    make_perfview
    set_ui_height_px(500)

    declare $i
    
    declare ui_menu $menu1
    declare ui_menu $menu2


    move_control ($menu1,1,3)
    move_control ($menu2, 5,3)


    add_menu_item($menu1, "Group 1 ", 0)
    add_menu_item($menu1, "Group 2", 1)

    add_menu_item($menu2, "Group 3 ", 0)
    add_menu_item($menu2, "Group 4", 1)
end on

on ui_control ($menu1)
    $i := 0
    while ($i<$NUM_GROUPS)
        purge_group($i,1)
        inc($i)
    end while

    purge_group($menu1,0)
end on

on ui_control ($menu1)
    $i := 0
    while ($i<$NUM_GROUPS)
        purge_group ($i,0)
        inc($i)
    end while

    purge_group($menu1,1)
end on

on ui_control ($menu2)
    $i := 0
    while ($i<$NUM_GROUPS)
        purge_group($i,1)
        inc($i)
    end while

    purge_group($menu2,0)
end on

on ui_control ($menu2)
    $i := 0
    while ($i<$NUM_GROUPS)
        purge_group($i,0)
        inc($i)
    end while

    purge_group($menu2,1)
end on
