I'm NOT writing symphonies, I just want to arrange simple well known songs from beginner violin books (e.g. Essential Elements for Strings) so a small group of mixed voice and instruments can have fun playing together. Example: Banana Boat Song - book version is shortened, I'll add the other 2 phrases. Lyrics require changing some note values. That kind of stuff.
MuseScore is free and easy enough but doesn't have a phone app that edits, just one that plays.
Notion (by PreSonus) is $149 desktop, and has a ~$10 iPhone app that does edit. However transposing from C to the key of D, it puts in 2 flats. G gets 1 flat. Bflat gets 1 sharp. All backwards. Went through the registration on the website, put in a help ticket, no answer. No record of the ticket. No way to contact a live person that I can see. So not likely to pay $149.
Symphonix Evolution, i've just downloaded on my phone but there's no desktop version.
I teach beginning violin at our local small midwest town music store. They may put software on the store computer that all the 10+ teachers can access, so that's a possible consideration. Maybe MuseScore is adequate for our simple needs. What do other people use?
I use MuseScore on PC and laptop. Never yet found a really good 'phone app for editing.... I actually suspect I wouldn't use a 'phone app in any sort of serious way - it's good to have a large working area with lots of windows visible...
Musescore has a very extensive set of plugins as well. The two I use are ABC import (for taking fiddle tunes from http://www.thesession.org which are 'notated' if you can call it that, in ABC format) - and - the MusicXML import - which I have used to successfully import files from Finale. Oh - there is also a PDF reader which I used once or twice, but the PDF score has to be an actual PDF document, not an embedded image in a PDF file.
Some folks say MuseScore can be difficult to use, and maybe don't like the way the editor works on a "bar by bar" basis if you are "composing something from scratch" making it awkward to simply insert a note and have everything "shuffle along", but if you're using it just to do simple, multi-voice arrangements of existing pieces - it's a breeze. And I suppose, once arranged, other students can just use it in play-mode on mobile devices ?
I actually spent - I think it was $40 at the time - on "Noteworthy Composer" before I discovered MuseScore... NC has never been used since...
I'm sure you knew all that already - my ramblings probably didn't help - just sort of saying that right now, I can't think of anything better for your use....
I seriously recommend not copying my mistakes. D'oh -
Please make your own, different mistakes, and help us all learn :-)
