Paul E. asked about this in some thread somewhere.


Here goes:

One very smart device is the Emagic Unitor8mk2.

Product Description


Emagic's Unitor8 MkII is the ideal communications center for the professional studio. When it is necessary to integrate tape and video machines, timecode DATs, and mixer automation with a large MIDI rig, the Unitor8 MkII is the obvious choice. Emagic's proven Active MIDI Transmission (AMT) technology provides particularly exact timing at all MIDI ports, even in a stacked system. An external click input makes it possible to drive Logic Audio from a percussive audio signal Ö for example, control the tempo of the sequencer with a previously recorded rhythm track. Not only an interface and synchronizer, the Unitor8 MkII is also a versatile MIDI patch-bay; step between programmable patches with a footswitch or select from up to 32 patches via MIDI program change commands. In the unlikely event of notes sticking while in patch mode, the panic button will quickly fix the problem. Compatible with your professional requirements both now and in the future, the Unitor8 MkII also features an updateable operating system.

The Unitor8 MkII reads and writes SMPTE timecode as LTC and VITC. The precision sync processor built into the Unitor8 MkII is capable of reading the LTC code from a master tape machine at even 10 times the original tape speed. Using VITC is desirable when the sequencer needs to be synchronized to video with frame accuracy; the Unitor8 MkII provides this frame accurate synchronization at all times, even during fast-forward and rewind. Thanks to the video in and output, you can insert a timecode display into the video with variable position and size Ö even in LTC mode. These features plus the advantage of ultra short lock times make Emagic's Unitor8 MkII highly desirable in all production environments where intuitive workflow is as important as the time you will save.

Stackable and Compatible
The Unitor8 MkII is fully compatible with any standard MIDI software under Mac and Windows 95/98 (drivers for Windows NT and Windows 2000 are in development). With its full set of connectors such as USB for Mac and Windows, RS232 (Windows) and RS422 (Mac), the Unitor8 MkII quickly fits into any computer environment. Up to eight* devices can be stacked and they will function like one big 64x64 MIDI interface (Mac: Emagic software or Unitor8 OMS driver required) with AMT** to ensure razor-sharp timing on every port. Unitor8 MkII, AMT8 and the Unitor8 can be combined in any combination; this allows, for example, the connection of a Unitor8 without USB to a computer with USB via an AMT8.

Features
Mac compatible: Directly supported via Logic Audio and SoundDiver, OMS, MTP emulation.

It must be either the mk1 or mk2 !

Howard has this one himself. He loves it. I don´t thnk he has used the sync stuff yet though. You can download the controller application from Apple´s site somewhere. I did that yesterday.

Suppsedly this one can sync from what ever click track you have slammed on on the tape. The smartest thing to do is of course to record the sync track first on free track and then get the tape machine running as master.
There will often be bleeding from the clicktrack so you must experiment a bit with how loud it has to be recorded on tape.
Re bleeding. A standard way to do this is to record the click on track 8 then not use track 7. If bleeding is a problem, then this is the way to do it. this leaves you 6 track free. Obviously what you want to get is a at least an 8 track machine.
