HI Geoff
First the gif. The first file was indeed gif, and second GIF (no idea why, I created them both by using the Snipping Tool to cathc the secreen and saving from there). I changed GIF to gif, and am inserting this, and you can see how much improved (by which I mean it is much closer to what it should be) than the first. All I did was try harder to play all the notes at once.
I'm not sure how I can send a midi file - it is not included in the supported file types.
I will now have to consider the second part of your message. I should first explain that I made the recording with "Red dot" - this is a very siimple program which which records the input signal and saves it to a Midi file on request. There are very few varaible parameters - you can ignore key pressure, channel pressure and program change. I ticked the first two, not the last for no particularly good reason. I then open the recorded midi file in Musescore and it immediately shows its interpratation of the file as a score.
I've played around with the Musescore settings as you suggest, and have got a much improved version, but it still thinks I am usually plaing the bottom note first (which I may be doing!). One of the things I checked was "is a human performance"!!
But i am climbing the learning curve under your direction.
I haven't been able to record the midi directly using Musescore - I will have to read the instructions more carefully...
Cheers
Catherine
