hey all, I'm currently using a Motu 8pre FireWire to record drums with 8 preamps available. I want to add more inputs to close mic parts of the kit and add room mics, what 8-input interface would anyone with knowledge on this recommend me pair with it that is able to add the inputs needed to get to 16 ins? I'm having a tough time figuring out what units are compatible with what or if I need another separate converter altogether. I would prefer to keep this as cost-effective as possible, even though that can be paradoxical with anything drum recording. I'm eyeing the Art Tubeopto 8, would love to try some tubes on drums but not sure if the Adat will add any available inputs to the 8pre. Any information and/or recommendation will be much appreciated!
