How automate the BlueArp Enabled button?

[Fabrice54]

Hi all,

I try to automate the Arp enabled button in Blue Arp but i don't know how...
I expose my problem:
Via "bome's Midi Translator", i create a toogle button to disable or enable Arp

When Arp is enable, all notes are sent to BlueArp, no problem, all work fine.

When i Push on the button to disable, i send CC 7B, it's mean all notes OFF.
Here, there are 2 kinds:

-If the keybed are release, no problem, the Arp stop, and when i push keybed again, the arp doesn't start. this is ok
-But, if keybed are allready press, when i disable Arp,(it's mean the soft send all note off CC),the Arp continue to play until i release keybed, so Blue Arp doesn't respond to this CC
I select in setting page " program change : set program".

I try the same test with another Arp (Kirnu) and i don't have this issue.
May be i don't configure correctly BlueArp, but i don't know where....

Thank's

PS sorry for my poor english, i'm french...
