MOTU Micro Lite [145/166] Locking a motu interface to smpte

APPENDIX B: SMPTE SYNCHRONIZATION BASICS

145

LOCKING A MOTU INTERFACE TO SMPTE

In order to sync your MIDI device to tape, you must ﬁrst

successfully lock your MOTU Express interface to the

SMPTE on the tape. To do so, you need to:

1. Stripe a tape with SMPTE

2. Connect the MOTU Express interface to the tape deck

3. Prepare the MOTU Express interface to convert SMPTE

4. Roll the tape to see if successful SMPTE lockup has been

achieved

These steps are discussed in chapter 8, “Synchronization”

(page 113). Once lockup has been achieved, you can stop

the tape, set up your MIDI hardware or software, and then

slave it to your MOTU Express interface.

Connecting midi gear 10
Here s a suggestion if you have more than a few pieces of gear connected to your motu midi interface jot down which device is connected to each input and output in the worksheet below later on you ll enter this information into your software so you can refer to devices by name 11
Interface this means that they share the same set of 16 midi channels so try to do this with devices that receive on only one midi channel such as effects modules so their receive channels don t conﬂict with one another 11

Daisy chaining midi devices 21
Freemidi and oms are industry standard midi system extensions for mac os 9 they allow midi software to talk to your motu interface and the devices connected to it they also provide uniﬁed midi system conﬁguration for example they supply your midi software with a list of midi devices connected to your motu usb midi interface as a ﬁnal step in the software installation process you need to run the freemidi or oms setup utility to specify what devices are connected to your motu usb interface for complete details see appendix d freemidi and oms page 151 21
If you have no choice but to daisy chain you need to conﬁgure each device such that it doesn t share any midi channels with other devices in the chain otherwise you ll 21
In general daisy chain midi devices as shown in figure 3 5 on page 22 should be avoided because it is more complicated to set up than connecting each device directly to your motu interface 21

Using midi software 25
As for midi data arriving and leaving your computer via the motu usb midi interface driver imagine it coming and going from the motu interface as shown in figure 4 2 all channelizing and ﬁltering is applied before the input data arrives at the computer and after it is sent 26
From the computer this is a great advantage as it frees up your computer and midi software from having to deal with the mundane and time consuming chore of such processing just conﬁgure your motu interface and let it do all the work 26
