Hey team
After talking to Presonus technical support and getting no definitive ETA on 44.1, I decided to call a major US music supplier to get an opinion on which board could do what I need. The knowledgeable gentleman I spoke with said that presonus is further ahead than anyone when it comes to I/O/daw control/live board combination units (the only company making a reasonable go at it according to him), he convinced me not to buy something else from him and keep my sl16s3. He also said that his technical guys are in touch with presonus development people and he would see if there was eta info available.
He got back to me saying his tech guy was TOLD BY PRESONUS DEVELOPMENT FOLKS THAT 44.1khz on STUDIOLIVE SERIES 3 BOARDS SHOULD BE READY THIS SUMMER
Even if it doesn't come it be, I immediately felt better knowing this is the goal. I feel if presonus would advertise this to us with a big disclaimer saying it's only the goal and may not actually happen on schedule, we'd all feel better and chill out.
Anyway, I hope this makes all who wait impatiently feel a little better.
