Item/Take volume with Mousewheel

That would call main() over and over again. Try this:

reaper.defer(function() main(false) end)

That was it, thanks! I'm going to add this "delayed undo" to all my "adjust x via mousewheel" -scripts

Somewhat related bug, fyi:

"...volume envelope point at mouse cursor via mousewheel.lua:1: unexpected symbol near '/'"

when I try to use your script spk77_Adjust volume envelope point at mouse cursor via mousewheel.lua

This script appears to not be working. Thanks!

@spk77
Could you add undo to these ones?

MoveUp envelope points.lua
MoveDown envelope points.lua
Compress envelope points.lua
Expand envelope points.lua

by the way, I found a bug in those, when selecting all points, the first one, at time 0.0, wasn't moved,
I changed this (in red) and it works now, but I'm not sure why.

for i=1,env_point_count do
      value = ({get_env_point(env, i-1)})[3]
      selected = ({get_env_point(env, i-1)})[6]
      if selected then
        e_i[c] = i-1
        e_v[c] = value
        c = c+1
        sel_points = sel_points + 1
        sum = sum + value
      end
    end

Does anyone know if there's a way of doing a time delay undo like this in a lua script?

          ph = vol < 0.0;
          vol = DB2VAL(VAL2DB(abs(vol)) + (val > 0 ? 0.5 : -0.5));      
          want_item ? SetMediaItemInfo_Value(item,"D_VOL",vol) : SetMediaItemTakeInfo_Value(tk,"D_VOL",ph ? -vol : vol);      
          cnt+=1;
          z=1;
        );
        idx+=1
      );
      tr+=1
    );
    cnt != 0 ? UpdateTimeline();
  );
  time_precise() < pc+1 ? defer("run(0)") : Undo_OnStateChange("Adjust Item Volume"); 
);

run(1);

Any way of changing the volume with scrollwheel, on razor edit selection? (instead of selected item). Would love that. I think the culprit is, that currently I can't select items with razor edit. Thanks
