Preliminary netlist sound for the Zaccaria 1B11142 board
* Tromba (trumpet) sound is not working - requires Schmitt trigger device * Connecting cassa (bass drum) swamps other instruments so it's disconnected for now * Mixing melody sound with speech/SFX is not done in netlist (should be) * Relative levels of melody/speech/SFX are probably still wrong (nw) A good test case for this is the Money Money driver (monymony). There's a bit of buzzing on this one as well. The problem with the cassa could be caused by running into non-ideal characteristics of opams again (the LM3900 seems to ignore the V+ value supplied to it). When the netlist library gets Schmitt trigger support, the tromba can be completed. Unfortunately, the tromba is a key part of the characteristic sound of these boards, so you really notice when it's lacking.
