I use a fantom x7 to send midi program changes to a Yamaha S 90. The fanton transmits this in live mode using an mix of performances and voices. The S 90 receives this in either voice mode and performance mode. So far I have fully functioning understanding here. Super. I am interested in keeping the fantom as a master but I want to play the fantom sounds on the S90. This gets complex since I now have the out and in from the fantom connected to the in and out of the s90. I have found that I can manage this configuration and can muddle thru it. ok. Now here is where I am asking for help... how does the fantom send program changes to the yamaha in the yamaha's MASTER mode. I can not decipher the manuals explaination and have not been able to use my experiences thus far to do it on my own. Please help if you can offer a solution and if you could make any of the tasks ive dicribed here any easier. Thanks
