Hello all. I recently purchased an electric cello and a guitar-to-usb connection (Behringer UCG102), to avoid having to purchase a full-blown amp for something I'm just going to practice with. After opening the box, I opened GarageBand and tried to get it to work, but (as the title suggests) I'm not getting any input. Other posts had suggestions that brought me far, however, still no dice. I have the input in GB set to USB CODEC, the output set to Built-In Interface, Input set to "Mono 2", and the monitor is on. At first, I thought it might be the instrument not interacting with the connection (the instrument has a passive pickup, so that freaked me out a second), until I opened Sys Prefs and saw that the computer receives a signal from the interface every time I strum (about 1/3 to 1/2 bars on average). This leads me to believe that GB is simply NOT receiving the signal. I'm about ready to rip my hair out over this as I just want to sit down and play already. Any help you guys can give would be appreciated. Relevant Specs: 15" MBP OS 10.6.8 (Snow Leopard) Instrument: NS Design NXT-5 Cello GarageBand '09 (5.1) EDIT: I just tested the instrument with Audacity and it receives a signal and I can record it, so I know for sure it's GB now.
