Unfortunately I have to agree with The Sphinx. For weeks I had a problem with Logic Pro 9 seeing Spark as a plug in, going by the limited instructions of 1. Make sure you're installed the latest version of Spark, that it runs nicely in standalone mode. I did this, and it does operate as a standalone. 2. In logic, go in the menu and select logic > Preferences > Audio Units Manager... When in the plug-ins manager, check that Spark passed the validation and that it's checked as available. If not, just check the tick box to make it available in Logic. I did this numerous times, and each time it showed up as "successfully validated", and check marked under Logic, but still it wasn't showing up under "Audio Units" when I clicked "inserts" on the software instrument track, and there is nothing on this site that tells you what to do if you follow the instructions and it still doesn't show up.
I tried going to a Guitar Center for help and had someone try to find Spark as a plug-in, but they couldn't. We tried uninstalling and re-installing Spark, it still didn't work. I contacted Apples tech support for Logic Pro. They couldn't figure it out either. They advised me to uninstall and re-install Logic Pro 9, and if that didn't work, that I would have to try and get back to Arturia. I re-installed Logic Pro, and it still didn't seem to work. I've tried to Google it...nothing, I tried Youtube....nothing again. A week ago I e-mailed my problem to Arturia.
I was still waiting for an answer when I decided today to try taking it to yet another Guitar Center. One of the guys there told another guy to see if they could get a product rep on the phone. I said to him, "there's a product rep in the United States?" He said yes. It was after 7pm eastern time where I'm at in the United States and I was thinking, if there's a product rep in the US, their probably gone home for the day. To my surprise he got a woman on the phone. The next thing almost put me into shock. In less than 3 minutes of the store clerk talking to an Arturia rep, the problem was solved. Instead of going to "inserts" on "software instrument" strip, you have to press and hold down the rectangular bar with the name of the default instrument that comes up directly under where is says "I/O", then go to the bottom where it says "AU Instruments". Everywhere else I looked made it seem as if it was under the inserts area.
Now I've got another problem, and the only place that I've seen on this site that seems to answer the problem is in one of the 4 Youtube videos that Arturia seems to have up. I need to know how to record drum patterns and songs into Logic Pro 9, and like The Sphinx says, the videos are blurred and going at about 200mph. It would also help if the videos had audio and the process written out step by step.
I've never had a piece of music gear give me this much headaches. Getting tech support is difficult, you can't get answers in a timely manner, theirs no tech support number to talk to anyone, unless you work at a music store, to get feedback if Arturia's stated answer to a problem doesn't solve your problem.
