TapeStop does exactly what the name promises. It's a Max for Live tape stop effect. You can set up and down time separately. Either in time or in beats. Then hit the TapeStop button (even repeatedly - try it, it's fun!) or map it to a controller. Have fun at your next gig!
It works with Live 8 and 9. And it's free.
This way for heaps more Max for Live devices & tips.
