Have not really got time for learning anything so complex. This was a compliment to all of you people, who can build things like this. Please learn me something new. Who should I contact ? Pleeeeaaase A desription of usage: I am the lucky owner of a Yamaha PSR-9000pro keyboard and just bought 2 midicontrolled light-dimmer-packs. it worked fine with my computer as the slave, but when I used the Yamaha keyboard as slave, it did'nt. Sadly the keyboard do not send note off codes. Then I thought of a "transelatordevice" and whoooops, I had some wishes to control the MAIN dimmer, so my hair dont burn off at special jobs with "not so much place". Whoooops, one more. Between midifiles it would be good to be able to control "the light" by using the memorypads on the keyboard. Sadly the transmitted channels can only be assigned to 1 PAD / TRACK per channel. I would be most thankfull for any help and solution I will get. BEST REGARDS KENNETH
