The Wow and Flutter will introduce delays but will periodically return to zero so the whole track will effectively stay in sync. The main fixed output delay is introduced by the motor start/stop section. If you want to minimise the any delays through the device and never intend to use the start/stop function, just set the "Motor Time" parameter to 0 :)
@offthesky - great idea I'll add it to my list of things to look at for V2.0
@Maerzmusic - glad you found a workaround. I'll see if there's anything that can be done in the next version.
I already have a few additional ideas to add for the next version, but if anyone else has any feature suggestions, let me know here and I'll do my best to include them.
