Product Description
As with any digital recording system, sound quality is a primary concern. That’s why Roland gave the SI-24 Studio Interface the best 24-bit/96kHz converters. You can use up to 8 analog inputs simultaneously, choosing from either 1/4 in. phone jacks or professional XLR connectors. Six analog outputs are also provided, plus S/PDIF digital I/O. Once audio is routed into the SI-24, it is transferred digitally in and out of the computer via R-BUS. And since Logic supports 24-bit/96kHz recording, the sound quality is never compromised. You can even dither back down to 16 bits when you’re ready to burn a CD.
Fully Automated Mixing
With 13 motorized faders, mixing on the SI-24 couldn’t be easier. Simply switch fader banks to access more channels and watch as the faders instantly snap to the proper positions! Naturally, the SI-24’s faders can also be used to control Logic’s "virtual" faders for more natural mixing. And when you really want to create complex mixes, tap into Logic’s wealth of automation functions. Tools like HyperDraw let you draw in fader moves and panning, while the new track-based automation makes it even easier to automate any mixing or plug-in parameter without leaving the Arrange window.
Dedicated Transport/Function Buttons
Besides functioning as a mixer, the SI-24 works as a remote control for Logic. Dedicated transport buttons and a large Jog wheel make moving around your song easy, while ten numeric keys perform multiple functions: Push the Screen Set button and they automatically select Logic’s screen sets, making it easy to switch between the Arrange window, Mixer window or other screens. Press the Short Cut button and the numeric keys automatically perform functions like Save, Undo, Copy, Paste and Cycle. They can even call up automation views for volume and pan. And that’s just the beginning!
Easy Editing with Real Faders and Knobs
Logic’s mixer makes it easy to see levels, panning and effects -- but who wants to mix with a mouse? Instead, try using the SI-24’s faders, buttons and knobs for a more "hands on" approach. To adjust a track’s level, for example, just grab one of the motorized faders and watch it change onscreen. And when you want to pan a track, simply select the desired channel and twist one of the Pan knobs. Similarly, you can use the SI-24’s multi-function buttons and knobs to set EQ and send levels. There’s even a dedicated Surround joystick so you can maximize the 5.1 surround capabilities of Logic RPC Pro.
