I recently acquired an audio mixer program called MixPad  and did comparisons with Audacity and Musecore as mixers/recorders.

Without getting technical, my go-to program became MixPad.  I was trying to piece together  a recording session using the best features from the different programs.  But again, I found myself using MixPad the most.   Great section for manipulating audio clips. 

The attached file is one I just about "created" but the violin does sound mostly like real life with me playing.  (I still can't hit high notes for a dXXX with my viola/violin.)

I know  there is much more to MixPad than I used.  It will take time.  I can imagine many opportunities for learning by means of recordings.

The attachment is WAVE from MixPad exports.  The MixPad default file is a very weird file type.   This is church music as some will know but I'm not crusading!
