I think the +Drive is geared mostly towards people that play live sets, and who need lots of songs and setup variations to carry them through a performance. The need for that type of capacity just isn’t as important if you work mostly in your home studio (like me). And if you’re the kind of person who likes to make a jam, record, move on and never look back, then you don’t need a +Drive (IMO). You can always make and record tunes as you go, creating more space if/when you need.

The MD still does amazing sounds design and sequencing without a +Drive. So maybe ask for a lower price. I think anyone trying to sell a MD without a +Drive these days is going to have to bargain a little.
