Gary, Thanks. Thanks for your input!
I did review this section of the tutorial, but the examples didn't reflect the simplicity of my inquiry. However, I found the resolve for the problem. There was a key point within a similar request after researching through the MACOSXAudio website: http://www.macosxaudio.com/forums/viewtopic.php?t=49188.
So in essence, all I needed to do was the following:
1) [i]Go to the preferences icon, select midi and the Midi Sync tab --checkmark the MIDI Clock's "Allow to send Song Position Pointer while playing."
2) [i]Select the "Midi Sync Project Settings" tab, and checkmark the "Transmit MIDI Clock - Destination 1" tab; then choose my midi interface (in my case it was the AudioBox USB), checkmark the "MIDI Time Code (MTC) "Transmit MTC" box, and checkmark the "Transmit MMC" box under the MIDI Machine Control (MMC).[/i]
3) [i]On my Alesis SR-18, I went to the midi controls under "system setup" and set the "Clock In" feature to "On."[/i]
The results were right on point. I proceeded to press the space bar on my computer to engage the logic sequencer, and it triggered my Alesis SR-18 Drum Machine. Super! Sorry I get a little impatient with the lethargic manuals. Logic is such a heavy equipped sequencing tool (too much I think), it just takes so much time to dig through the parameters for simple stuff.
