Thank you veru much for the great advice.
For me, the things about $80 things are totally unknown and unexpected and it was the last peace to make it work!
I am so excited that I now can control my effector fro BCR2000!
By the way I have got an another new question about BCR2k function.
I would like to control the level of the effect, that the value of -61 to 0.
I know how to make a 14bit hexadecimal number for negative value.
But BC Manager's Value1 and 2 setting(looks like encoder on display) shows only positive values to set.
How can I set the negative value (e.g. -61)?
