    Try this out and give me feedback please. Especially mentors!
    I've built a series of ten tuning exercises, tuning ten different unisons. The ten notes start at G1 and go up by fifths into octave 6. 
    Each note starts out of tune, a wobbly unison, within a range of 3 cents flat or sharp. There's a tuning hammer that you can turn 1/2 cent at a time and hear how the unison changes. When you think you've got a perfect unison, you click the YES button and if you're wrong, you can try again; if right, you go on to the next unison. 
    It's a very interesting exercise. Please listen with headphones if you can. I think you can leave feedback at the right side of the window, or respond to this message - especially if something doesn't work right. It's still early days.  https://360.articulate.com/review/content/ab33a675-b1fa-4933-bc4c-f220a29734fc/review

    Ed, please try again? I'm on a different device, and just clicked the link in your message, and it loaded in less than five seconds in working order.

    Jason, it loaded fine for me.  I will get some feedback in a bit.   It loaded fine on my phone also.

    There must be some snag in my computer, but I just sat for five minutes watching the dots turning without the page loading.

    Jason, that was a lot of fun!  I can think of two ways of scoring a person's performance.  One is to count the number of wrong answers.  The other is the measure the length of time a person takes to complete it.  Maybe combine the two into a single score of some sort.  I didn't measure my time but I think I got three wrong answers.  It did feel very natural after a couple of notes.  Well done!

    Really helpful indeed! A particularly great test and valuable training and I've forwarded it to a couple of people on the path.

    Best wishes and festive greetings

    Hi Jason! Very good tool! I did notice a couple interface behaviors that could be improved. 
    1)  I noticed that if you wait until the current note is completely gone before moving the lever, moving the lever triggers the note to play the next sample. I like this, because it lends to quick comparative judgements while moving a unison. But, if you're too quick, and move the lever before the last note/sample has finished, it doesn't trigger the sample at the new offset, it forces you to play the key "manually" on the keyboard graphic. This seems a bit counterintuitive to me. 
    2)  I'd suggest that each time you move the lever, the note should immediately trigger at the new offset. If you touch the lever again without moving it, it should immediately play the current note again with out changing it, even if the previous playing of the sample has not finished. 
    3)  If you swipe to move the lever, but you're not quite on it, and instead are in the surrounding field, swiping makes the whole frame drag. I think the frame should not be movable. And perhaps the target could be made a little larger, so it's more likely to "do what you mean."
    4)  When all this is running smoothly, you might consider increasing the number of notes. But as it is, I think it will be found very helpful for training. I like it!

    Thank you for this great exercise Jason! I sent it to someone I've been mentoring. Haven't heard back from them yet but I'm sure it will be helpful for them.
