current release of single strand MUST have timing marks. If you use the PLAY button all the way to the left, you will nothing. Only the PLAY buttonnext to the open icon will work. I will be enhancing the singlestrand effect to not require timing (Like all other effects in Nutcracker), but for my show i wanted timed chases. i did say i was releasing single strand with only half its functionality so people could get started.
as mentioned you can always use spirals to create chases on arches,. spirals so NOT need any timing to get them to move.
thanks
