    Recording 15 ips on a 7.5 ips Reel to Reel
    I am new to Logic 8 but I do have some experience with Logic Express 7. I have two reel to reel tapes that are 15 ips but the reel to reel that I have only does 7.5 ips. Is there a way in Logic 8 to record the tape and make it sound at the right speed? Also, what's up with Soundtrack Pro? Do I even need to use it? Doesn't Logic do everything I need. I am sorry if this is the wrong forum to ask this second question. Thanks all!

    I'm no expert in Logic, but spent many years on tape machines! First up, are these multitrack tapes or stereo masters? Either way, you'd really be better borrowing a 15ips machine to do this. The bias settings will screw with your sound, and also you'll get a worse signal to noise ratio runnig the tapes on the 7.5 ips machine.. But, if you can't, and someone's forcing you, I suppose you could use Logic! You'll need to use a pitch changer to raise the pitch by an octave, and also you'll need to speed the audio (tempo) by a factor of 2. I'm not near Logic so I'm not sure what the tools/plug-ins are called. But, be aware that this is pretty severe processing, and the sound quality is going to suffer.

    Hi Just to add to this thread, you don't [i]need[/i] to use Sound track Pro 2, but it's very useful as an audio editor - really useful for applying effects to parts of a piece of audio, great for audio to video and adding and removing ambient noise. You can also use it to send audio to from Logic as an extended audio editor. Check out some of the preview videos for the SoundTrack Pro tutorials: [url]http://www.macprovideo.com/tutorial/soundtrackPro2[/url] Also look at the Logic 303: Logic TNT tutorials (April's edition) for Steve H's more advanced uses of Logic & STP for a taster of a further creative use. Cheers Rounik

    Yes. Essentially your recording is 1/2 its natural length and and octave too low. Record it into Logic. Bring it up in the sample editor. Open up the Factory/Time and Pitch machine. Select and algorithm that best describes you track. Then near the bottom of the window enter 1200 into the transposition box. (1200 is 12 half steps which is, in turn, an octave). The process!! I would try this out on a short piece of audio first to make sure you've got it right because this can take a bit of time to crunch the numbers on a large file! Good luck, Steve H.

    You will also need to change the tempo because your track is playing at half speed. So enter 1200 into the transposition box as Steve suggested and enter 100 % into Tempo Change (or double the tempo BPM). Christian

    Thanks for the soundtrack Q&A I had thought that myself because I haven't used it yet. Thats cool you got some reel to reel work, if it all works out maybe you could post your music so we can have a listen

Christian[/quote] Or, select the "Classic" mode which will effectively do the same thing. From the manual: [i]The Classic mode is for situations where you want to transpose a selected region, and also affect its tempo. This produces an effect that you are probably familiar with, as it simulates the sound of changing tape speed. This mode changes the pitch, sonic character, and playback speed of the audio material.
