Arp Tempo as Mod Destination

It would be cool to be able to modulate the Arp/Seq tempo to make it more dynamic.

I have some patches where I arpeggiate a chord and modulate the tempo by hand, which is a really nice effect, but it would be great to be able to do it with a mod source.

I think I could do it with an external clock, but would be cool to not need to!
