I see a few references to this Royal Schools of Music software from 2011, some of which seem to
indicate that it doesn't work, or at best, works very poorly. I encountered the software for the first
time at Morris practice last night, and as far as I can see/hear, it's working, and looks to be rather
useful. I've installed the Windoze version...
It is possible to speed-up, slow-down tunes for practice purposes, plus other things. It seems to
work on .mp3 files - I haven't looked to see if other formats are allowed.
The current version seems to be from 2018.
The software can be downloaded here. I've installed the Windoze version, I can't speak for any
other OS.
There's a page describing other training/learning software here, though I haven't investigated
this page yet...
