my friend with Logic Pro 9 can send files to me but they cannot accept files created with Logic Pro X.
Which is exactly what i said earlier....
You can open Logic Pro 9 projects in LPX but not the other way around.
Apple wouldn't even give me a refund on Logic Pro X (purchased just 3 days ago), which is useless to me now.
There are no refunds from the App Store... That is what you agreed to when you purchased a license for LPX.
Your choice is simply for your friend to update to Logic Pro X or use the audio stem process I outlined earlier (Not something i would recommend doing for any period of time)... or spend even more money on purchasing two copies of a different DAW... and taking the time to learn them and spending time converting over what your friend has already created... and hope your friend hasn't been using the internal plugins found only in Logic Pro... otherwise you have even more work to do...
The reality is, the sensible solution is simply to upgrade LP9 to LPX for $200... (and think of it as the upgrade price even though you can buy the full version for the same amount but that really doesn't matter does it?) Less outlay, less time lost and less hassle, but as always the choice is yours...
I have never, EVER, encountered a software company that treated customers that way.
Then you haven't been in the computer business that long...... 🙂
Seriously though, you haven't been treated that badly...
You bought LPX at a price that is basically a steal.... and your friend bought LP9 at the same 'deal' of a price.. compared to what Logic Pro used to cost ($1000)
You can 'upgrade' from LP9 to LPX for $200 which is much cheaper than it used to cost to upgrade from , say LP8 to LP9... and the same price as it cost to upgrade to LP9 via the App Storeprior to the release of LPX
The alternatives at this stage would cost you much more money......time.. and hassle..
The only things that truly frustrating is the timing of your friend's purchase of LP9... For that he has my sympathies but it happens... Some people who bought Logic Pro 9 within a month of Logic Pro X being released were given refunds on the LP9 purchase if they bought LPX... Your friend just left it way too late.... Apple has since stopped such refunds.... and you didn't do the research you should have done before you jumped in and bought LPX... Unfortunate but sadly true.
Again, you and your friend have my sympathies for whatever they are worth... but at least the obvious solution is still cheap compared to what the alternatives could cost you now and in the past!
