Has anyone used the pa4x with a computer and virtual instruments? I have been trying for 3 days to get my MacBook pro os 10.14.6 to recognize my pa4x. I am using the free kontakt player 6 with Alicia Keys pianos... I can get my Roland RD 2000 to work with it but not the PA4X.... I am using the usb port from the back of the pa4x to the mac usb in. I have tried every combo of midi settings in the pa4x... (i think)
The mac does allow for the pa4x to play the alicia keys piano but it won't send the sound back to the pa4x speakers. Any thoughts would be appreciated.... thanks Ron

Is the USB socket on the PA4x a Midi & Audio interface, as with a lot of keyboards it is just used for Midi, thus you need to connect the audio output of the Mac to the audio input of the PA4x to produce sound. (If it does do audio, make sure it is showing up in the Macs sound manager, and Kontakt is connected to it)
Also make sure everything linked to the USB interface is turned on.

I think you are correct on maybe the pa4x doesn't have audio within the usb. It does not show up in my mac sound manager. When I use my Roland keyboard, it does show up in the sound manager. I will try what you suggested regarding the audio out on the mac and the audio in on the pa4x. Thanks for your help.....

Hello,
I think there is nothing sent back to the pa4x speakers but I'd rather guess that your Pa4x route its midi information to both the Mac and the internal sound generator.

If so use the Internal/External parameter to connect the corresponding part/track to the internal and/or external sound generation.
Go to track control page of pa4x and set groups (Upper1-3, Lower ...) from "Both" to "external".

Thanks for the suggestions... I did get it working but it just sounds like crap... I guess the pas speaker does not do it justice as far as the sound. I am thinking of selling the pa4x and stick with my Yamaha Montage and Roland RD2000 along with my Roland Integra and GEM Rpx piano module. I get an awesome sound with combining those ... thx Ron

If anyone is interested in my pa4x with the pas speaker system just send me a message. It is like new and played very little... Always covered... Just a year old in November.. thx Ron

How much would you want?

I would sell it for 2500.00 with the PaAS speaker.... Shipping would be additional. I would think shipping would be under 100.00 to Saline MI from Binghamton NY... I also have all original packaging.... thx for asking... Ron

I decided to drop the price to 2400.00 if anyone is interested... This is in immaculate condition and has never been moved. The PaAS speaker was 435.00 alone... If anyone is interested let me know... thanks Ron

Hey Ron. You seem to belooking for a new piano for your 4x. Have you tried the free Yamaha C5 Grand available here:
