Thank you very much for your answer and the precision of this one. You have enlightened me perfectly and I understand much better the operation of my 2 hammond (44 and hyper). After checking and based on your explanations I am relieved …. my two Hammond melodicas are relatively correct. I also want to say that I particularly appreciate your achievements (and that of the people who are part of your team) on youtube …. they motivated me a lot to put myself in the melodica. see you soon !!!!
I have a gift for you from Jakarta, you will be pleasantly surprised maybe, these four videos on youtube could be interressed! :
