Play new arp while track is muted, unmute to play new arp

[Jameslondon74]

Would be great if you could:
1- play an arp
2 - mute the track
3- while muted, you can play a different arp, to get ready
4 - unmute track and hear the new arp

At the moment, if you play the arp while a track is muted, it halts the arp altogether.

thanks!
