Reconsider how the 'cut' command works.

In allmost all applicatons 'cut' removes the phrase or note but does not alter the time line. In SFP one must copy, then clear, in order not to change the position of later notes.

A small change, but one that brings more 'uniformity' to other music software.  The 'Delete' command is still there your intention is to remove and have following notes move forward (an equally valuable tool).  The more commands and processes that have a roughly similar counterpart in DAWs - you should follow previously set standards.  Then the user will be more able to learn the esoteric feature faster. 

NOW I GET ON MY SOAPBOX (IVORY)

It's just like the record business (or the way it used to be) You have to be 'different' but not too different that you can't make the song fit with others on a play list.  As brilliant as SFP is, if it had a bit more similarity - it would be more user friendly.  I truly have  to rate this one of the least user friendly music applications (BUT I LOVE IT).

For the last week, I've put aside all other music projects and been working on just one SFP song, experimenting with as many features as I can assimilate.. There are still whole areas that  escape me.  But first I'll become comfortable with the more elementary processes, then move on to learn the harder ones.  

I notice sometimes because of your familarity of program, you're explaination leaves a bit desired cause the new user can't get thru the first part of your explaination. Example = on Logic with SFP.  You open the 'time' parameter, I didn't get that until the third viewing.  I assumed it would be under 'synchronization' as it is on all other DAWs.  A small point, But one that many might not get.  Of course if there were a voice, or you zoomed in and selected 'time' I would have got it the first time...

I did some newspaper writing in college. We were taught the first principle was to write for an 8th graders level. 

While SFP is definetly post graduate work, you want your explainations and manuals to be more geared for an 8th grader. The faster and more gratified the user is, the more he will work towards mastering the program.  Indeed some people might use it for a much more elementary use than you had in mind.  But they'll become a customer and gradually through short and concise videos and explainations, they will be motivated to reach a higher level of understanding of this GREAT program. 

IMHO - and with respect..
