I am able to play and get sounds. Here are two problems:
1. I am getting no volume changes with breath strength changes.
I am using X-custom and have selected CC2.
I have not changed any of the setup switch settings.
2. I am not able to play fast tongued passages- simply does not sound.
I am able to tongue a single note fairly quickly.
3. Not able to play any way near as quickly as the acoustical clarinet, in general. I have only used this thing for about 15 minutes. Maybe I need to be patient and treat it like a new woodwind which needs some small embouchure and key manipulation adjustment, such as between sax and clarinet, for instance.
