I have two of these very well made transport cases that came directly from Alternate Mode the company that makes Drumkat midi drum controller units . All of the zippers work on each case and they each come with the original heavy duty shoulder strap included . These costed $299 each back when they were bought new and were only very lightly used . I have an Anvil case that both of my Drumkat controllers fit into so these have been just sitting . Each of them is designed to fit a Drumkat controllers unit , cords , power supply all inside and they have a large size front zippered pocket for extra storage . I'd like to get $250 for each case , but I will consider a reasonable cash offer on one or both of them . These will fit other brands of multiple pad controllers too so if you need specific measurements of the inside dimensions just let me know .
