In the latest version of the Synchron player manual it says on p. 31 "For technical reason, time stretching currently applicable to legato articulation (in a musically correct way)."
This sentence has no verb, I have no idea what it means.
The main reason I bought the synchronized solo strings is to control vibrato in a flexible way, as you mention on the page describing this product. How does it work?
Thank you,
