• • • 54 slower MIDI clock transmission rate. You can see the tempo change on the Studio 5’s MIDI IN LED for that device; it will blink slowly at slow tempos, and very rapidly at fast tempos. You can slow down the Studio 5>Macintosh communication speed. Decreasing the communication speed will give the Macintosh more time to “see” the incoming MIDI data, and will help if the Macintosh is busy with a lot of output as well as input. If you’re using only one serial cable between the Macintosh and the Studio 5, try using two. OMS applications, such as Vision and Studio Vision, will receive data generated from within the Studio 5 out the Studio 5’s “B” port. This includes time code, Studio 5 footswitch and foot controller data, as well as Audio In note events. All other data coming from MIDI devices connected to the Studio 5 is received from the Studio 5’s “A” port. If you are running a non-OMS application, select Studio 5>Compatibility Setup in OMS Setup and select either Standard Interface In or MIDI Time Piece In. Make sure that sync and only sync is sent out the Studio 5’s “B” port (the Auto button will also do this). If you are running Vision or Studio Vision, select Setups>Enable Input Devices and only enable those input devices from which you will receive MIDI. If you have 15 devices, but you only play one or two of them when you record, disable all other inputs. • With Studio Patches you can design Virtual Controllers to filter out MIDI clock messages, active sensing, or any other offensive data. You can then use these Virtual Controllers instead of the actual devices. In Vision or Studio Vision, select Setups>Enable Input Devices, then enable the Virtual Controllers and disable the actual devices on which they are based. For non-OMS applications, choose Studio 5>Compatibility Setup, select either Standard Interface In or MIDI Time Piece In views, then replace the unfiltered devices with their corresponding Virtual Controllers. Studio 5 will not sync to tape Make sure the power cord is firmly inserted into its connector, the power switch is on, and that the SMPTE/Power indicator light is lit. Check all the cables between your computer and the Studio 5, and between the Studio 5 and your tape deck. Verify that the SMPTE/Power indicator light blinks when it is receiving time code from the tape deck. If not, you may have a bad cable or connection between the Studio 5 and your tape deck. Also, your SMPTE level may be recorded too low. If so, you may need to use a preamp or mixer to boost the SMPTE level before sending it to the Studio 5. See Guide to Setting SMPTE Levels (pg. 33).
