DAW means Digital Audio Workstation - better said, your computer.
Which motherboard, how much RAM, which Scope card etc. etc.
A screenshot could be made with the "print screen" key. Drag the windows on your Scope GUI so that we can see your problem, press "Print screen", open a little graphic program, paste and save as a jpg-file. Put this file on a server and copy the URL into your new message body, so your screenshot should appear.
Or you post your problematic project at "projects" here in the PlanetZ forum index.
To your problem "sts won't work": You can only drag p-files from an AKAI-CD (they have a little keyboard as icon) into the main window from sts. If you try to drag s-files (with a little wave as icon) into this window, it won't work.
If you want to work with single drum sound samples, you have to create a NEW program in the main window of sts, then you have to open the key group window, then create a NEW keygroup, click on OPTIONS, a window appears, click on ZONES and then on SAMPLE. You can see 4 slots and to here you can drag your single sound.
For more informations read your ... manual. And don't forget to save your new sts-program on a location where you can find it next day.
Good luck, Thomas
