This would probably be very difficult to implement, but the idea of having multiple of the same instrument would be one of the biggest game changers ever introduced to online sequencer. With the way that OS works currently, it's incredibly limited. It simply doesn't allow you to use any instrument in more ways than one. This is unfortunate considering just how unique you can make each instrument sound using various effects and distortions.
