Hello melodeon forum members. I am a new player and new forum member from the USA. I am learning to play a Favorit II BbEbAb instrument. I am doing well with the right side, but the bass buttons (12) leave me bewildered. One post that I viewed on your website referenced this instrument as having a "staggered reverse" layout but offered no further explanation. Can anyone direct me to a resource that explains this? I have sent several emails to Delicia for assistance, but they do not reply. I have called a Delicia dealer in the US who said they would research it and reply later but also have not responded. I also have a Hohner Panther GCF and understand the intuitive layout that Hohner uses. Thanks to anyone who can help me with this. Pat Kautzer
