Global Speed Control for all Groups

Hi everyone. How can I set a global speed control that effects all groups? Also, do all the groups have to be in time machine pro mode, or a mode that shows a speed control?

The code below doesn't work, but if I change the $ALL_GROUPS to 0 then it works properly, but just on group 1.

on ui_control ($speedsld)
set_engine_par($ENGINE_PAR_SPEED, $speedsld, $ALL_GROUPS, -1, -1)
end on

As always thanks!

 

You would need to use a while loop and instead of $ALL_GROUPS use the loop counter.

$ALL_GROUPS is mostly only used with purge_group(), you cannot use it with get/set_engine_par.

 

What does the while loop have to contain?

while ($counter < $numgroups)

inc ($counter)
end while

 

That set_engine_par() line from your first post, but with counter instead of $ALL_GROUPS.

 

When I do that with the while statement above, it doesn't work. My speed slider doesn't seem to effect anything.

 

Works fine here.

Code:

on ui_control ($speedsld)
    $count := 0
    while ($count < $NUM_GROUPS)
        set_engine_par($ENGINE_PAR_SPEED, $speedsld, $count, -1, -1)
        inc($count)
    end while
end on

 

Gotcha thanks! I wasn't putting the set_engine_par within the while statement. Still new to this. Thanks for being so helpful!
