!USB Interfaces Manual Book Page 21 Tuesday, October 10, 2000 12:43 PM CHAPTER 4 SMPTE Sync and MMC with a Windows Sequencer USING MOTU USB MIDI PORTS There are only a few simple preparations you need to make to take advantage of the powerful MIDI routing, SMPTE synchronization and MIDI Machine Control (MMC) features of a MOTU MIDI interface and any Windows sequencing software that supports SMPTE synchronization and MMC.
!USB Interfaces Manual Book Page 22 Tuesday, October 10, 2000 12:43 PM interface as shown below in Figure 4-2. All channelizing and filtering is applied before the input data arrives at any software input port and after it is sent from any software output port. 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.
!USB Interfaces Manual Book Page 23 Tuesday, October 10, 2000 12:43 PM The first step is to slave your sequencer to MIDI Time Code as described in the previous section (and shown in Figure 4-3). of passing on MMC record commands from your sequencer and the MMC device. Just send them directly to the appropriate Windows MIDI port. The next step is to establish MMC transport control of the MOTU interface from your sequencer. To do so, make sure your sequencer knows the MMC Device ID of the MOTU interface.

!USB Interfaces Manual Book Page 27 Tuesday, October 10, 2000 12:43 PM CHAPTER 5 Working with Presets OVERVIEW This chapter describes your MOTU Express interface’s eight factory presets and explains how to: The eight user presets can be configured any way you wish, and they can be stored in the interface hardware itself for later recall.
!USB Interfaces Manual Book Page 28 Tuesday, October 10, 2000 12:43 PM MIDI Express XT front panel preset controls micro express front panel preset controls Figure 5-1: The eight factory presets on the front panel of the Express XT and micro express. Each factory preset is described in the following sections, including situations in which you would find it useful.
!USB Interfaces Manual Book Page 29 Tuesday, October 10, 2000 12:43 PM For the micro express, input 1 is routed to outputs 1-3. Input 3 is routed to outputs 4-6. For the Express XT, input 1 is routed to outputs 1-4. Input 5 is routed to outputs 5-8. MIDI Machine/for the Express XT This preset provides MIDI data, time code, and MIDI Machine Control settings for using MIDI Machine Control between devices without a computer.
!USB Interfaces Manual Book Page 30 Tuesday, October 10, 2000 12:43 PM USER PRESETS Your Express interface provides eight user presets, which you can configure any way you wish. From the factory, these eight user presets match the eight Factory presets described earlier in this chapter. To change one of the eight user presets, use the Express Console software as described in the next section to modify and save the user preset in your Express interface itself.
!USB Interfaces Manual Book Page 31 Tuesday, October 10, 2000 12:43 PM CHAPTER 6 Using Micro Express Console About Micro Express console Micro Express Console serves as a “control center” for the Micro Express. For example, you can make changes to the synchronization settings, filter some data on a particular input or output, or route MIDI data from any MIDI device to any other MIDI device connected to the Micro Express.
!USB Interfaces Manual Book Page 32 Tuesday, October 10, 2000 12:43 PM ☛ THE TOOLBAR Before covering some of the other main elements of the toolbar, we’ll quickly define the functions of each of the buttons, or “tools”, along the bottom. These functions will be covered in greater detail in the following sections. You may activate one of these functions by simply clicking its associated tool (shown above), or by choosing its equivalent menu command as shown below.
!USB Interfaces Manual Book Page 33 Tuesday, October 10, 2000 12:43 PM The Setup list will always contain the eight user Setups followed by the eight factory Setups. Selecting a Setup from the list with the mouse will cause the Micro Express to change to the selected Setup. You can also use the keyboard up and down arrow keys to scroll through the list, pressing Enter to select the desired Setup. Alternately, you may use the Micro Express’s front panel buttons to change Setups.
!USB Interfaces Manual Book Page 34 Tuesday, October 10, 2000 12:43 PM WINDOWS MIDI PORTS As for data arriving and leaving your computer via the included Windows MIDI driver, imagine it coming a going from the Micro Express data bus as shown in Figure 6-5. All channelizing and filtering is applied before the input data arrives at any software input port and after it is sent from any software output port.
!USB Interfaces Manual Book Page 35 Tuesday, October 10, 2000 12:43 PM MIDI ROUTING WINDOW The MIDI Routing window is the control center for routing and processing MIDI data with your Micro Express. Although your computer will always be able to receive MIDI data from the four inputs and send data to the six outputs with your Windows MIDI sequencing software, the Console has the ability to configure the Micro Express to internally route MIDI data from any input to any combination of outputs.
!USB Interfaces Manual Book Page 36 Tuesday, October 10, 2000 12:43 PM Naming ports Naming the MIDI input and output ports is easy. Simply select the desired port and press Enter or directly click on the current name with the mouse. A pop-up edit field will appear containing the current name. Edit the name and either press Enter again to save it or Esc to abort the changes. The names you enter for the ports will be displayed and remembered in the Console.
!USB Interfaces Manual Book Page 37 Tuesday, October 10, 2000 12:43 PM Removing routings To “unroute” a routing, you first must select its source and destination. The isolated routing connection will be shown bolder than the other routings (as in the right-most example in Figure 6-8). Pressing Delete or Backspace will remove the routing. You can also drag source icons to the Clear icon to remove all their routings.
!USB Interfaces Manual Book Page 38 Tuesday, October 10, 2000 12:43 PM appropriate window to be “brought to the top”-another one will not be opened. Alternately, the Window menu will always contain a list of all the open Console windows from which you can select one to activate. The Sync In and Sync Out icons The Sync In and Sync Out connectors represent MIDI Time Code (MTC) routing to and from the Micro Express itself.
!USB Interfaces Manual Book Page 39 Tuesday, October 10, 2000 12:43 PM Express “listens” to MMC transport commands from any devices (or computer software) connected to this icon. MIDI messages (those that are not sent on a particular channel, such as “System Exclusive” messages). For MMC transport control of the Micro Express from the computer, enable the transport master option as shown Figure 6-18 on page 45. Doing so makes the Micro Express follow MMC transport commands sent from software.
!USB Interfaces Manual Book Page 40 Tuesday, October 10, 2000 12:43 PM Filtering channelized messages Each channel in the Channelized section has its own filtering settings. Think of the channel selection as letting you step through the 16 different filter combinations on each channel on a particular port (as conceptualized in Figure 6-14). Clock messages are from a general class of MIDI messages called “real time” messages.
!USB Interfaces Manual Book Page 41 Tuesday, October 10, 2000 12:43 PM 2 With the port selected, click on the channel map button above the selected port as shown in Figure 6-7 on page 35. 3 Now, with the Channel Map window open, select the channel you wish to remap on the left side and enter the new (remapped) channel on the right side. SYNC WINDOW The Sync window is used to configure the Micro Express’s many synchronization features.
!USB Interfaces Manual Book Page 42 Tuesday, October 10, 2000 12:43 PM Frame lock The Frame lock check box is only available when LTC or MTC is chosen as the master sync source. It is not available when you are using internal mode or LTC QuikLock mode. To understand the Frame lock option, you first need to know that the Micro Express continuously monitors the time code to which it is locked (either LTC or MTC) to detect any possible discontinuity in the frame times as they advance.
!USB Interfaces Manual Book Page 43 Tuesday, October 10, 2000 12:43 PM This slider lets you control how many frames in a row the Micro Express needs to receive to consider incoming SMPTE as being parked on a single frame. While lowering this value makes the Micro Express more responsive when you park on a frame with your video deck, it is also more likely to misinterpret ordinary transport shuttling.
!USB Interfaces Manual Book Page 44 Tuesday, October 10, 2000 12:43 PM TOOLBAR SYNC DISPLAY The toolbar Sync display provides detailed information about what state the Micro Express is in as a synchronizer.

!USB Interfaces Manual Book Page 71 Tuesday, October 10, 2000 12:43 PM CHAPTER 8 SMPTE Synchronization OVERVIEW ACCESSING SMPTE SETTINGS This chapter explains how to use your MOTU Express interface to synchronize computer software and other devices to an audio tape recorder (ATR), video tape recorder (VTR), or other time code sources using SMPTE time code. It also explains how to generate SMPTE (a process commonly referred to as striping).
!USB Interfaces Manual Book Page 72 Tuesday, October 10, 2000 12:43 PM steadily as well. For the micro express, the lights on the front panel are arranged slightly differently than what is show here on the XT, but they perform in an identical fashion. If the LOCK and TACH lights do not behave as described, your Express interface is not successfully locking to the SMPTE time code. This could be a problem with the audio connections between the tape deck and your Express interface.
!USB Interfaces Manual Book Page 73 Tuesday, October 10, 2000 12:43 PM see “Frame lock” on page 42 (for micro express users) or “Frame lock” on page 62 (for Express XT users). Slaving a sequencer to your Express interface To slave a sequencer to your Express interface: 1 In your sequencer, make your sequencer look for MIDI time code from the “Sync” input. This is the virtual input from which MIDI Time Code is received from the MIDI Express interface.
!USB Interfaces Manual Book Page 74 Tuesday, October 10, 2000 12:43 PM Take care after using the offset/start time The LTC Start setting in the Express interface serves as the start frame when striping, but also as the offset when reading. If you stripe at 1 hour (1:00:00/00) and then lock to the time code you just striped — without readjusting the offset/stripe setting back to zero (0:00:00/00), then the Express interface converts starting at 2 hours (2:00:00/00).
!USB Interfaces Manual Book Page 75 Tuesday, October 10, 2000 12:43 PM Fresh SMPTE Time code Original SMPTE Time code MIDI Express XT or micro express Lengthening a SMPTE track If the time code on your SMPTE track ends too early and you need to add more code, you can use the “One time” jam sync option. To do so, feed the original track into your Express interface and record the fresh code onto a new track.
!USB Interfaces Manual Book Page 76 Tuesday, October 10, 2000 12:43 PM When your Express interface operates in MTC mode, it locks to any MTC coming from your computer. In doing so, however, it also “swallows” the MTC coming from the computer. If you attempt to transmit MTC from your MIDI software to a specific MIDI device in your studio, it won’t reach the MIDI device because it will get read and “swallowed” by your Express interface.
!USB Interfaces Manual Book Page 77 Tuesday, October 10, 2000 12:43 PM CHAPTER 9 MIDI Machine Control OVERVIEW Your Express interface can serve as a MIDI Machine Control (MMC) transport control “hub” for all MMC-compatible devices, allowing you to manipulate the transport controls of everything from one master set of controls: either an MMC hardware controller device such as JL Cooper’s CuePoint or from MMC-compatible MIDI software on the computer.

With the MIDI Timepiece AV, you can, in most situations, choose which device will be the master. And you can even choose different, independent master sources for transport control, time base, and address.
!USB Interfaces Manual Book Page 119 Tuesday, October 10, 2000 12:43 PM Basically, QuikLock mode is a way of achieving faster lock-up time in situations where you do not need the MIDI Timepiece AV’s digital audio synchronization features.

Routing MIDI Time Code At times, you may need to route MIDI Time Code to a device connected to one of the MTP AV’s MIDI OUTs. Similarly, you may have the need to route MTC to the network port on the MIDI Timepiece AV. For example, the network port might be connected to a Macintosh, which you need to slave to time code.
!USB Interfaces Manual Book Page 126 Tuesday, October 10, 2000 12:43 PM You can use the SMPTE Controls window in the MIDI Timepiece AV software or the MIDI Timepiece AV front panel LCD to generate SMPTE. This section covers how to do so with the software. See “Using the SMPTE controls” on page 108 to learn about how to stripe SMPTE via the LCD display. Note that the MIDI Timepiece AV always generates fresh time code while reading existing time code.
!USB Interfaces Manual Book Page 127 Tuesday, October 10, 2000 12:43 PM Of course, if you want to stripe a tape and meanwhile get on with other work, you can quit the MIDI Timepiece AV software. Striping will proceed in the background. Striping frame-locked LTC onto video The MIDI Timepiece AV can stripe LTC onto video while syncing to the video, ensuring that the LTC is frame-locked (i.e. LTC won’t drift out of sync with the video frames).
!USB Interfaces Manual Book Page 128 Tuesday, October 10, 2000 12:43 PM Timepiece AV receives a SMPTE signal on its SMPTE IN cable, it always regenerates a fresh signal that exactly matches the incoming signal and sends it out the SMPTE OUT cable (except for drop-outs, which it eliminates with freewheeling). 4 When the levels are set, roll tape and convert as normal.

!USB Interfaces Manual Book Page 131 Tuesday, October 10, 2000 12:43 PM CHAPTER 13 MIDI Machine Control with the AV OVERVIEW The MIDI Timepiece AV can serve as a MIDI Machine Control (MMC) transport control “hub” for ADATs and all other connected devices, allowing you to manipulate the transport controls of everything from one master set of controls: either an Alesis LRC (or LRC-compatible device) connected to the front panel of the MIDI Timepiece AV, or from MMC-compatible MIDI software on the computer.
!USB Interfaces Manual Book Page 132 Tuesday, October 10, 2000 12:43 PM There is no advantage to doing MMC this way; in fact, it will probably not provide as stable a time base as the MIDI Timepiece AV does in the recommended scenario described in the previous section. You should only really use this setup if you have a MMC device that does not have the ability to be a time code slave and therefore must be the master.

For most MMC devices that support being an MMC slave, routing time code (either MTC as just discussed or LTC) to them is all you need to do. For some devices, you may also need to get the MIDI Timepiece AV to send MMC transport commands to the device.
!USB Interfaces Manual Book Page 134 Tuesday, October 10, 2000 12:43 PM Generally speaking, once you’ve successfully established overall MIDI communication between your software and the MIDI Timepiece AV, all you have to do is tell your MMC software what the MMC Device ID is of the MIDI Timepiece AV. not have the ability to be a time code slave and therefore needs to be the time code master.

!USB Interfaces Manual Book Page 146 Tuesday, October 10, 2000 12:43 PM WHAT IS LTC? Longitudinal Time Code (LTC) is the audio form of SMPTE Time Code. LTC consists of an audio signal that oscillates between two frequencies (approximately 2 and 4 kHz) to form an 80-bit word of 1’s and 0’s for each frame on the tape. The 80 bits in each SMPTE frame describe, in binary form (1’s and 0’s), the location of that frame in hours, minutes, seconds, and frames.
