Welcome.
Sorry to hear of your problem, can I ask you to clarify if the Piano is working at all?
If the transportation of your P60 was via a paid for service then they are liable for the damage and hence should pay for the repair.
If it was DIY transportation then to damage the jack would have required quite an impact. Without further research quite possibly if the jack socket is attached to the electronic circuit board then that in turn may be damaged to some degree, hence hymI asked if the Piano is functioning.
Your Macbook has or can have the free Apple App called Garage Band, if you do not have it, then if you install it and then plug in using a standard USB cable and you are good to go. I will leave it for others with more knowledge of the MIDI connection interfaces to answer that part of your post.
BTW. There are plenty of Youtube tutorials on using Garage Band.
If all works fine then yes, add an interface, but I would not get an interface yet, just make sure things work first.
The sustain pedal on a digital piano is only a simple switch, and if you know anyone handy at DIY then could always open up the piano and solder up a flying lead with a socket on the end of the lead to the circuit board where the existing jack socket connects, then your sustain pedal will function by simply plugging in the pedal into the socket on the end of the flying lead.
Biggies,
I did transport it myself. It's just a little piano (probably weighs 40 lbs at most). I have no idea how I broke it. Sometimes things happen to me that I could not do if I wanted to, and tried to do. -_- All I know is, it was working fine in the home of the person who sold it to me. I took out the cord for travel and when I got home, the jack was broken. Audio out works fine. Power cable jack is fine. I haven't tried the MIDI connections because, again, I really have no idea what I am doing with that. I took off the outer shell of the piano and figured out that what I believe to be the circuit board the input is attached to, is completely broken off and severed from the rest of the circuit board, which has all of the other inputs and outputs connected to it.
There are only 3 shops that repair these things within a 2 hour drive and all want well over $400. I just do not have it right now. I do have a friend that is handy with electronics and knows how to solder circuit boards but I'm guessing at this point I would probably need a whole new circuit board for all of the inputs and outputs since they are connected to the same piece? I don't think it would work to solder the pieces back together? Where would I get a new one?
I'm sorry I sound so uneducated right now. I can figure out computer codes, tell you in detail about any world history event, excel at math, fix any computer software issue, but electronic hardware.... that's about where all that intelligence comes to screeching halt. I took apart an almost new iPhone once to replace the screen and couldn't get it back together. I was scarred for life after that when it came to hardware issues so I refuse to touch this and I'm almost afraid to have someone else even do it for fear of making a bad situation worse.
I think I'm going to download garage band and see if the MIDI works first. My computer ONLY has a USB C connection (Apple's way of making us pay more money for connectors) so I ordered a USB-C to USB connector cable today. I am hopeful that there is nothing wrong with MIDI connections since they are on the same side as Audio out and power and those work fine. (The sustain pedal is on the far side and that is what broke off). I guess I will find out when my cable gets here.
Thanks for the help!
