MT 2.1- I like it! Still great 7 years later!

It's quite amazing what MT 2.1 does for just a couple of bucks, considering you can pay several hundred bucks for a Tascam slow downer device and around fifty for some of the current computer-bound guitar/riff/song software packages. Those products do a lot of other functions, too, but the fundamental and most desirable feature for learning songs with any of these programs or devices is the ability to slow the songs down significantly without introducing noise artifacts. MT does that quite well and you can change key easily too.
Some reviewers have complained that it's not so easy to enter songs into MT 'directly' from your IPhone. But how you do this is basically just like adding a song to an ITunes playllist: go to a web site, upload the song via an "upload" (browse) button, and then ITunes syncs it into MT. I'll be interested to see if even more features are added to later versions, but I'm very impressed with MT 2.1 and still find it hard to believe I got it for just a couple of dollars.

Still great after using it for 7 years!

Works well

The app seems to work well so far.
Only issue is the app struggles with variable bit rate mps files. It only shows 0 to 23 seconds of the song at a time and is pretty much impossible to select a phrase from variable bit MP3 song. I was able to slow down an speed up but unable to choose a phrase to loop over.
So works well with fixed bit rate but not variable bit rate encoded MP3 files.

Worth every penny - almost perfect!

As with other reviewers, I own a Tascam CD-GT1 practice tool and it is still one of the most useful pieces of gear I've ever used. A couple of days ago it occurred to me that an iPhone app might exist with similar functionality. Turns out there are a couple of them out there, but I believe this one is the best available thus far. The ability to create and save many phrases within a song is brilliant - no more resetting loop start & end points as you work on different sections of a song. The WiFi upload is flawless. My only complaint echoes other reviewers' comments that frequently used buttons could be larger to improve ease of use. A landscape layout might have helped in that regard. I have also occasionally experienced audio dropout during looping, but this is quickly rectified by pausing and restarting playback. I would also like the ability to make fine adjustments to the start and end points of phrases while audio is audibly scrubbed, but I don't know if the iPhone has enough processing speed or horsepower to enable this. In all, this is an incredible value and I am thrilled with this app. Most reviewers complain about high prices - I would have gladly paid double the price for this app! I look forward to updates that address users' comments.
