I used to have a S2000. It does not have waveform display editing. You have to edit by ear. It has one simple low-pass filter. It's ok, but the OS wasn't designed very well, and you have to scroll through sh!t loads of screens to get to the thing you want to adjust, and then scroll back again....all on a tiny little screen.
If you want that type of sampler, step up to the S3000xl. It's has similar capabilities to the S2000, but it has waveform editing, and the OS is set up WAY better. Also, the multi-output board is stock. It's way more user friendly and faster to get around to the different functions.
In fact, if you want to buy one, PM me, I'll sell you mine.
