The new versions released yesterday have a problem with MIDI presets, which are now incorrectly sent on one higher channel than the desired channel (e.g., a preset intended for channel 3 will be sent on channel 4). I already have a fix and will submit it to Apple within the next 24 hours.
Meanwhile, the easiest workaround is to adjust your receiving equipment to accept the MIDI messages on the incorrect channel.
If you can't do that, and you have MIDI devices defined in your database, you can edit your MIDI devices and lower the channel number for each device by 1 to compensate for the error. In this case, you should edit the MIDI device with the lowest channel number first, and work your way up. Unfortunately, you cannot use this to fix program changes sent on channel 1, because you cannot lower a device channel to 0.
If you do not have MIDI devices defined in your database, you can define them now for every channel you send MIDI presets on. You should first create the MIDI devices on the desired channels, then go back and edit the channel for each device to the compensated value.
As always, I recommend waiting until version x.x.1 or x.x.2 of a major release if your performance schedule does not allow any app downtime.
