interval identification, exercise 21

[jcs37]

The exercise is designated as diatonic tones in the key of C. However, I believe that the intervals are both chromatic & diatonic. Am I correct that this is a mistake? Am I correct that the exercise is is out of sequence in the Tutor, or, in other words, is too difficult for its position in the exercise sequence? If so, are there plans to change it?

Lesson 21 is the same as lesson 20, but in lesson 21 the intervals are played descending. It is not out of sequence, but you are right there is an error. Some of the intervals are not diatonic as they should be.
We will fix this within the next couple of days. You can use the "Check for update" function in the "Help" menu to find out when the update is available for download.
