Metronome and looping

[brabuse]

I'm having a great deal of trouble using adjusting the metronome in Morphwiz. I can get the tempo close to what I want with the slider but to get exactly 100 BPM (for example) I have to fiddle with it. It's almost like pure luck when I can set the metronome to the desired tempo. How about a tap up and down button on a future update. Also, AudioBus compatability would be fantastic.
I use this app in my school (I'm a music technology teacher) and I love the interface. I bought 20 copies for all of my students to use and it's by far the winner with my students for user friendly interface (Soundprism is next)
It is hard to use MorphWiz with other apps though as Morphwiz will not allow me to loop a short chord progression (say 4 bars of bass and drums) that I have AudioPasted in and then record a solo played on Morphwiz over it. I only get the 4 bars before I'm playing over what I already recorded.
