1. Seems like preview listening in Finder is adiquate. But, if it could also read the Serato library that would be helpful because that's really the issue - Finder is lame compared to Serato's Library. But maybe that's tough to build in.

2. Personally, I'm using like five to nine sample a time it's fine for me. But I think it should have a keyboard set up. I'm usually using MPC with 16 pads, but sometimes I'm using a keyboard and knowing which sample goes to which key is annoying, maybe in that case 2 octives of keys?

I'm using Reason 9.5 and I can't preview any Audio before I load it into serato which is annoying

Preview in Finder (mac), select the file before you drag it in, press space bar.

@akeim hi thanks for the reply, I'm using windows, is there any way I can use a preview feature in windows or is it only for use on macs?

I haven't touched a pc in years so I don't know the answer to that.
