All,

We recently acquired a CS18ai, Rm32 and Studio One 3 for our studio (rehearsal, live recording and music production studio).

I followed all the advice, watch a lot of videos, read a lot of documents and completed the installation as required however i still can't get the system to function correctly.

Allow me to describe my set up a little:on the network side I have a Router connected to the internet, a MOTU AVB switch, RM32, CS18ai and an iMac. I also have an iPad.
The RM32, CS18ai, Router and iMac are all connected to the AVB switch via Ethernet cable (CAT6). The router provides DHCP. The RM32 is also connected to the iMac via a Firewire cable. The ipad connects wireless to the Router. The wifi dongle on both the RM32 and CS18ai are removed.

I switch ON the router and the switch first and wait 5 minutes before switching ON (in this order) the RM32, the CS18ai and finally the iMac.

Some days i can control the RM32 from the cs18ai most days i can't. Power cycling many times sometimes yields results sometimes it doesn't. The UC control software from the iMac controls the RM32 everytime as it sees it as a firewire device.
On the UCNET menu, the CS18ai sees the RM32 and when i start Studio one 3 on the computer it sees that as well.
The ipad also controls the RM32 correctly. All my firmwares are up to date have tried many approaches to solve my problem.

The first approach was to reserve IP's on the Router for the CS18, RM32, iMac and iPad so that they would not get different ip's each time they were switched on, that changed nothing.

The second approach was to in addition to the reserving IPs on the router to assign static IPs on the CS18ai, RM32, iMac and Ipad that matched those reserved for them on the router. this worked the first day i configured it (i had control of the cs18ai from iMac and iPad and could also control the RM32 from the cs18ai), but stopped the next day. One very odd behavior was that I stored a scene with all my mixes and settings and named and saved it, the next day it had disappeared.

This is where i stopped trying different things and started pouring into the forums a little more to check for any solutions.

Today the CS18ai would not work at first with the RM32 not could the the software control the CS18ai (not is DAW). after a few times power cycling the cs18ai, it just came to life and everything started functioning the way it should up until i could not hear a few on my instruments despite their faders being lifted and assigned correctly. after looking a while longer I discovered that the UC surface on the iMac had a mute of those faders, and the CS18ai was not showing the mute as active nor was it removing the mute when i press the button. i had to remove the mute from the software first and then only was i able to use the mute button successfully on the CS18ai.

Your help in solving this would be very welcome as we are a small business and we have invested all our hard earned money into this setup and as things stand we are not able to reliably say to our future customers that we provide recording services if we can't rely on our equipment.

Oh and by the way, our studio is located in Nigeria, Lagos, we acquired our Presonus gear via their local agent and we do not enjoy the 30 days return your gear if not happy option.

Regards,

Marwan
