Hey dude, this site is way badass!
It has potential up the wazzoo!
Can I ask how much storage you have and what that costs per month?
I'm fucking nutz about organizing my samples.. Thankfully I realized a long time ago how important it is to meticulously organize your sheez. I've often thought about how Ableton needs to have meta data options for samples and device presets, but since they don't, it really just comes down to organizing them by location, folder name, and file name.. then using the search bar to your advantage.. But..
THIS is GREAT.. this kind of organization is exactly what you need as a producer.. but the thing is.. I need an offline program that can sort through my samples..
..cuz what this site really has to offer in terms of organization, is it helps you find the exact sample you wish to preview & download.. then it gets mixed back in with the chaos that is your sample library.. ya feel me?
So I don't see myself using such a thing for more than a couple days..
Your organizational system isn't the only thing the site has to offer, as long as you successfully implement your other ideas of allowing people to sell their homemade sample packs. That would be super chill.. plus your system of earning download credits by uploading is a great way to ensure that your constantly cycling through fresh samples.
Overall, you've done a great job and it has a lot of potential. I'm excited to contribute and watch as it expands.. I'll also add your site to my affiliate list on the music production forum I'm working on so my peeps can check it out!
