    Thanks Brian, This does look smooth. The problem is that this kind of libraries probably depend on support for specific displays. I'm saving all the good things people suggest here and will take a look if I need...

    Thanks Jim, I've started my own little thing here, just what I need, which is not much. I'm half-way done. Looks like it may be longer to accommodate other people's things than make your own. Hope do be done in a...

    I just do "new AudioConnection(...), like you show. You don't have to call ->connect(). If you don't need it, just "delete". It disconnects. Having them "pre-made" is a pain, as you need to give each a new name. I...
