Reply to MIDI Fighter Instant Gratifcation mapping

I'm trying to copy one feature of the new midi fighter mapping onto my Akai MPK Mini - it's the super combo one in the video. I've got the beatmasher bit already, I just want the transpose function - I currently have my button mapped to do the following:

- Select effect Transpose Stretch
- Button>Direct - set value to 1.000
- Button>Dec - coarse, auto repeat
- Turn effect on - hold

However, there seems to be a delay between pressing the button and it starting to wind down the sound (decreasing the effect parameter). I'm guessing this is because I'm telling it to set the value to 1.000 and also telling it to decrease, but there doesn't seem to be the same delay in the video. Any ideas?
