this moved me to tears but not in a good way, it hurts my ears... 1) sounds like a pretty stock digital piano, anything will do, just try compressing the shit out of it and EQ with a lower midrange notch and and an upper midrange boost if it lacks sheen, i would start with a cut around 350hz and a boost at 6khz maybe and tweak until it sat. then maybe compress it some more, no, defintiely comrpess some more, its really compressed.... strings? compress the life out of some ROMpler strings, its one fo the msot irritating soudns I've ever heard. EQ with peaks, not shelves so the vocals have more 'air' and sound clsoer than the isntruments
2) vocals? get a group of guys who sing decently together in abrbershop ahrmony and then autotube the shit out of them to the point of stealing their humanity? Youa ren't doing this wthout multiple singers and lots of antares or similar tuning software. The real key is the 4 distinct voices in well-developed harmonies. If you do it on your own without auto tune software at best you will get Queen's Bohemian Rhapsody with lto of the same guy in ahrmony. at worst you will get mush. You aren't known for your singing.
I really am not sure why you would want to replicate anything n this... it is so artificial sounding it made a trickle of blood come ut of my ears. I got a minute in to hear the other soudns you asked about and started to cry.
also, compress the shit out of everything and then compress the music ina group, the vocals in a gorup and then use a tone of bus compression, this is compressed until all the dynamic range has been squeezed way probably with layers of gentle and reasonable comrpssion as I suggested... oh, and after you put some VCA bus comrpession on the mix whack any remaining dyanamics off with L2 ultramaximizer to make it extra flat and lifeless. This is everything I hate about modern music. OH! mastering? send your finished song that's over compressed and over-tuned to a coke-head new york amstering engineer and tell him to make it the loudest song without rums on the radio and pay top dollar to ehar him destroy all the nuance with brickwall limiting over your already lifeless and soulless music. If Iw ant soulless music I'll listen to real amchine music like kraftwerk or soemthing.
I am tempted to say soemthing really cruel right now but I won't since i have a track record of getting in your face when you say things thata re way outside of my worldview. if you like this go look for a studio itnernship in india and learn all the modern pop tricks, your Baliwood (spelling?) has this sort of 'production' down.
