It seems that the behaviour of Ermaster 6.1 is not correct when using a microphone ....
the metronome stops after only one reading of the score (in the other case, the number of score readings is unlimited).
Thank you for this wonderful tool.
I am not sure I understand what you mean. Could you be more specific and give us an example (which activity, which lesson, what happens exactly after each click).
If EarMaster stops playing after one bar and tell you that you answered wrong even though you didn't sing anything, then it means that your mic picked up ambient noise which triggered the start of the evaluation. In that case, you could try adjusting the mic input sensitivity in Tools-->Mic Calibration Tool
