I wonder if anyone has a measure for the period of time it takes between a button being pressed and a note being sounded?
I realise that this will vary from concertina to concertina and even from reed to reed, but what I am trying to find out is what would be an acceptable maximum value for this latency on a good quality instrument.
I am asking because in building a midi concertina there are various places where delays occur and the sum of these delays should not exceed this maximum acceptable value.
