I’d like to practice playing a musical instrument (a 34-string lever harp) by playing in sync with previously recorded or synthesized music.
In the past when I’ve tried to use my computer or phone to play a song, I’ve found it starts right away and I am not able to get my hands into position fast enough to play the first few notes in sync with it.
I would love to be able to sit at my harp, choose all or some of a piece, select a tempo, push a button, have a lead-in, and have my fingers on the strings ready to play along before the song itself starts — and it might be even better if the playback automatically repeated. It’d be cool if it could give me advice on where I’m messing up, but let’s not go crazy here 😉
Is there any software that might help with this? (If I had some additional hardware, like a USB footpedal, is there any software that then becomes more useful in this regard?)
Are there any tools, perhaps, that, instead of modifying the playback with a lead-in, easily modify a (copy of) the audio file itself, to add a lead-in?
While F/OSS that works on my Mac is my preference, it is not a requirement.
