Hands down one of the best apps ever! After years of trying to use hardware slowdown devices, and being disappointed I finally feel there is something truly excellent! Being new to Bop Jazz its a little bit intimidating to attempt to replicate Charlie Christian,
especially at 224 BPM. Further, a lot of the old recordings were off by a few cents making it even more difficult including the retuning. I will definitely buy the Mac version. The documentation is superb and beats almost all the apps I own by a mile! Guitarists every where need this its complete, sounds great and extremely versatile!
