How to get synchronized digital audio from a Roland VS-880, through Logic Express, into GarageBand.

connect the VS-880 coaxial S/PDIF output to the M-Audio Delta DiO PCI card in the G4.

connect the VS-880 MIDI out to the MIDI in on the Midiman MIDISport 2×2.

in the Delta DiO preference pane
> in the monitor mixer tab
>> mute all other inputs except the S/PDIF.
> in the hardware settings tab
>> set the sample rate to 44.1 kHz.
>> leave the “Locked” box unchecked.
>> set Clock Source to S/PDIF Input.
> in the S/PDIF tab
>> set the Input Source to “Coax (RCA)”

on the VS-880, for each song, do this:
> press [SYSTEM] several times until you get to “SYS
Sync/Tempo?”.
> press [YES].
> press PARAMETER [>>].
> the display will show “SYS Syn:Gen”.
> rotate the TIME/VALUE dial and choose “MIDIClk”.
> somewhere else in the VS-880 (i can’t remember where), you have to also set the clock to “INT” and the fps to “30″.

in Logic Express
> Preferences > Audio > Drivers > Core Audio
> [checked] Enabled
>> Driver: Delta DiO
>> I/O Buffer Size: 512
>> Recording Delay: 0
>> [checked] Software Monitoring

> File > Song Settings > Synchronization > General
>> Sync Mode: Internal
>> [checked] Auto-enable external sync
>> Frame Rate: 30 fps

on the VS-880
> enable one audio track, pan it hard left.
> play some recorded audio and set the levels.

in Logic
> select the first audio track to record on.
> make sure that track’s input is set to “1″ (select this in the “Channel” parameter on one of the left panes).
> make sure the track is record-enabled.

> hit Play on the VS-880. you should see some audio in the Logic track 1 meter, and you should hear the VS-880 audio coming through Logic.

> on the Transport window, hold down the Toggle External Sync button and select MIDI Clock Sync.
> make sure Auto Sync In is selected.

> hit Record to put Logic in record-monitor mode.

on the VS-880
> go to the beginning of the track and hit Play. Logic should respond by going into Record and chasing the MIDI clock of the VS-880.
> let the whole track play all the way through the song and then pad it with 10 seconds past the end of the audio.
> press Stop. Logic should stop by itself.

in Logic
> drag the handle for the just-recorded track to get rid of most of the silence. leave a few seconds of padding before the song starts.

> double-click the waveform for the recorded track.
> in the Sample Edit window, go to “Audio > Save Selection As…” to save a copy of this audio selection to a separate folder where you’ll keep your GarageBand audio and project files. you can import these right into GarageBand and they should line up perfectly.

> repeat for each track you need to pull from the VS-880 into Logic.
