Software Instrument Tempo Issues in Logic Pro X
I am having a lot of trouble understanding the software instrument tracks in Logic Pro and how tempo works within them. If you record into logic using a software instrument as an input, there seems to be no way to separate the track from the project's tempo. I.e., I record into logic at 120bpm and then I speed the project tempo up to 130bpm, the software instrument track speeds up with it. This is fine in some cases, but in others I really want to be able to "unlock" this from the project tempo.
One other incredibly frustrating issue I'm having right now, is that this tempo locking feature seems to be completely throwing off my attempts at recording variable tempo tracks. So I have created a tempo curve from around 110bpm to around 120bpm. I then turn on the metronome and hit record on my software instrument track. I record along to the metronome, and then listen back, and the track is just completely out of time. I think what's happened is that logic has embedded in the track a flat 110bpm tempo, and then while I've sped up with the project tempo while recording, it's not taken that into account. Then once the track is fully recorded, logic goes and speeds up the track again to match the tempo curve. Not what I want! How can I make sense of this?

I wouldn't usually post two answers for one question, but this is a completely different approach, so here we go. Both work, but this might be more what you are looking for...
Record some MIDI data at a particular tempo.
Select the region, right click, then go to SMPTE Lock->Lock SMPTE Position.
Change the project tempo at the point where your region begins.
Unlock the region SMPTE Lock.
Change the project tempo at whichever point you like (for instance, for the whole piece).
Move MIDI region as desired.
Bounce your software track to an audio track. It should then stay at the same speed, unless you specifically ask Logic to change the speed of the audio. You can bounce any midi region using the shortcut Ctrl-B.
