I wouldn't mess with bit depth. Logic Pro will only let you choose 24 or 16 bit. Logic does upgrade to 32 bit, for processing audio, running thru it's filers, reverbs, etc.
but it returns it to 24 bit (or 16) when you output.
So in Logic, you only have the choice of 16 or 24 bit recording, you can select sample rates, 44.1K up to 192K
Don't know what each DAW does.. I do believe some DAWS offer you more choices.
If your using Genos digital out, you have to set your DAW to accept that (or it might do it automatically).. I tried Genos digital out, going thru my old but expensive RME Fireface 800.. But, the Genos audio out, seems slightly clearer, and a lower noise floor than the Tyros, so I usually just use the audio outs. You can get really anal about noise floors, sampling rate, bit depth. You can spend many thousands of cleaner A/D and D/A converters too..
And then you can go listen to a well recorded and mastered song from the 1950's, and ask yourself, 'Why am I spending all my money and making myself crazy..
Setting your levels carefully, and getting a good arrangement and performance are far more important.
Different folks have different opinions about sample rate. Some set up to highest (192K I guess).. But then your files are 4 times larger, and that presents a more work for your CPU..
Different studies, claim, you can't hear the difference over 24 bit. Other studies, and individuals claim they can.. When you reduce it to mp3, 4, other formats, and ear buds, I don't
If you are recording incredible music and want to be able to re-master, if a newer cleaner format comes out. I would go for the higher your DAW can do..
I've made a number of CD's, records, TV commercials, I make it 24 bit, 44.1K I think 24 bit, 48K format is pretty popular.
Then if you get all crazy about this stuff, it's pointless if you have a $400 speaker set-up.. I spent about $2,000 a number of years ago on Genelec 8040A's. I love them. I can hear that the acoustic guitar player needs to file his wedding ring finger, if he is playing without a pick.. In the last few years, a lot of improvement has been made on very reasonably priced speakers..
Take it all with a 'grain of salt' - I however am on a salt and sugar free diet. So this is a juggling act, of all the above factors, your budget, etc.
