Anytune Pro+ is one of a number of transcription tools for guitar, along with software such as Ronisoft Amazing Slowdowner, Sevenstring Transcribe, Riffstation and a few others, the aim being primarily to slow down tricky bits of guitar playing and be able to notate them. One of the key features of these apps and programs is the ability to loop sections, slow them down (whilst retaining pitch) and tune recordings to the record (i.e make learning tunes by those who tune to Eb easier, like Jimi, Stevie, Nuno and Eddie). It seems that Transcribe has one other feature which is great as it uses frequency analysis to break down the frequency content into pitches and chords. This is fantastic, but for me is one step too far as it take away from one of the key elements of transcribing, and that is improving your ear. I always think of it like attempting a crossword, but where the answers are given at the end of the paper, it is so easy (maybe it is just me) to get a bit stuck, and rather than really figure it out....look at the back and cheat. I see this feature of Transcribe as the equivalent of this, but I am sure I might use it at one point!Anyway, back to Anytune.Anytunes is a very comprehensive tool for analysing guitar playing (and of course for other instruments too, I recently read of someone using this for learning drum parts). One of the main things I love about it (on the iPad) is because it is so easy to drag loop point with your finger and actually see the wave form, I love waveforms, so it is so easy for me to set up points to loop around. The next thing I really like about this is the 'trainer' function, think of this like a personal trainer at a gym getting to work harder up to a certain speed. In the app, this is known as Step-it up, basically you enter a start and end tempo and Anytime gradually increases the tempo as your loop around, getting you closer and closer to your target speed, a great tool for practising I think!! Along with this, there is a Loop Delay feature, so you can pre/post roll looping to give you some time to think before the loop starts again!In terms of slowing down music for transcription purposes, you can slow down the piece without changing the pitch down to around 0.05X the tempo and up to 4X the tempo and as mentioned before you can adjust the pitch to tune to a different key.  Like other transcription tools you can also save your loops, but along side that you can also add 'Audiomarks' to label parts of a song, e.g. Intro, verse and also add comments (you can share these with your mates via email...that is pretty cool.) Along with the slowing down tools, you can use the FineTouch EQ to cut out parts of the song (eg reduce bass etc) to help you pin-point the guitar lines.There is a 'LiveMix' function, which enables you (if you have an iPad interface, e.g. iRig) you can play along with the track in really time, I haven't tried this with AudioBus, but I am sure it will work, so you could use this as a backtrack player at a gig for example.Anytune Pro+ is SO easy to use and had some many useful features! I still have Amazing Slow Downer on my Android phone, and use it from time to time when trying to figure bits and pieces out, but for the serious work it is Anytune now!Enjoy.PeaceNeil
