Great app so far. This is the solution I have been waiting for for quite some time. The interface is very user friendly and intuitive with a very small learning curve. I have not tested my mashups on a big system yet, so hopefully the Eqing sounds proper. Any "shortcomings" of the software can easily be addressed with simple workarounds. For example 2 tracks only- reimport your finished mashup again and then add your new track for your 3rd track. No fx - bring mashup into your DAW or Traktor for that last pass edit. Negatives- I was able to make the app crash after doing multiple undos (i will send the MIK guys a formal FYI if it happens again) The auto save did not work in this instance :( I am only 2 days into using it and with just a little more experience I can foresee being able to bang out a great mashup in 5 minutes! Cheers!
