You don’t mention your Logic setup, but I’m assuming you have Channel Splitters connected to the appropriate ports on the Physical Input and that these Channel Splitters are wired sequentially to Logic Audio Instruments. Also that you have created a “No Output” track in the Arrange Window and selected it as the playback track.
You also don't mention which version of Finale you are using. This is important, because, in my experience and that of some colleagues the Mac version of Finale 2006, has very serious MIDI playback problems with
1. Frequent stuck and missing notes - - which can, under certain conditions, make Gigastudio unresponsive to MIDI input.
2. Uncertain response to pushing the stop button in Finale 2006's playback controls when playing back scores with a large number of staves – requiring repeated pushing of the stop button, which eventually works but leaves behind a trail of stuck notes.
3. Sending extraneous sync messages to other applications even when “Send MIDI Sync” is turned off in Finale 2006’s MIDI Setup dialog box. (When using Finale 2006 with Logic 7, it is essential to turn off “auto-enable external sync” in Logic’s song settings.
There have been three maintenance updates of Finale 2006, but none have addressed this issue. If you are working with Finale 2006 and encountering these problems I encourage you - - and any other forum readers who have encountered these problems - - to write to MakeMusic - - as they have been unresponsive regarding this issue, apparently preferring to allocate resources to endeavors assessed as more “glamorous” than mere bug fixes that would only affect that part of the user base not completely dazzled by Finale GPO.
On the other hand Finale 2005 does NOT have playback problems to anything like the same degree. Finale 2005 does, however, exhibit stuck or missing notes when playing back Logic through either the IAC drivers or Finale’s own virtual Outputs, but there is an easy fix for these problems.
Go to:
http://pete.yandell.com/software/Download: MIDI Patchbay (Version 1.0.1)
Using MIDI Patchbay create a document directing the IAC ports (or Finale’s own virtual ports) to Logic’s Ports. Save this document and open it when you wish to address Logic from Finale. (If using Finale’s own virtual ports it is important to open Finale first - - to make these ports exist, MIDI Patchbay second, and Logic last. If using the IAC ports - - which are established by the OS - - the order in which you open the applications does not appear to matter.)
Also, if you use Finale 2006 and encounter the playback problems I mentioned at the beginning, you can use MIDI Patchbay to buffer output to external MIDI devices by selecting Finale’s own virtual outputs as the output device in Finale 2006’s MIDI Setup dialog box and directing these ports to the intended external output device in MIDI Patchbay. This makes the problems less frequent and severe, but does not, unfortunately, eliminate them, at least in my experience. Using MIDI Patchbay one also can, simultaneously, address Logic as well external devices by assigning the IAC ports to Logic and Finale 2006’s virtual outputs to the external devices. Again this is an imperfect workaround, but it does offer some improvement for those who must use Finale 2006.
I hope this is helpful.
