I recently bought a Fender Expo Array powered speaker system and also a passive YAECCC mixer board and I have tried to connect the PX-S3100 using the 1/4 inch Left (mono) output from the keyboard to the 1/4 inch Left (mono) input on the mixer board and then to the Fender speaker system using the 1/4 inch output channel from the mixer board to the Left channel of the Fender speaker. The YAECCC mixer board cannot even find the signal. What am I doing wrong? Is there an internal switch on the PX-s3100 when sending out audio to the mixer and then to the external speaker. I already turned the internal keyboard speaker output off, but I am still not receiving any signal from the piano to the mixer board and conversely to the Fender speaker. Is there anything else I need to know. Please advise. Thanks so much. David

Hello Guys, Wondering if you can help me with my problem. I require more REGISTRATION BANKS (beyond the 24 internal ones, with the 4 presets per bank). I have tried the USB Flash drive, which does not increase or SAVE for that matter, my presets. I want to be able to "lay down" more "Transposition, rhythm/instrument styles, split-points, and other assignable parameters". I need extra registrations for all the new repertoire I am working on and wish to "call up" on a dime at my gigs. IS THERE A WAY to add more registrations through either a flash drive, or are there any external modules that can be connected to my keyboard, re MIDI or USB to affect these requirements?? If not, is there "music software" that can be downloaded that INTERFACES with the CASIO (communicates) and perhaps I can run my "registration patches" off a TABLET or LAPTOP???? Please help me with any ideas that you might have.......GETTING DESPERATE. Cheers, David S
