I'm making some tests with the SAA1099 and I can produce lots of sounds but I can't set the envelope duration. I have tried different values for frequency and octave of the channel 2 (I assume a 0-5 channel number) and in fact the length of the envelope varies but it's always very short. There is any way to produce long length envelopes like we do in AY-3-8912?
By the way, what is the meaning of the bit 5 (external/internal clock) and bit 4 (16/8 bit resolution) on the envelope registers?
Note: I am using SimCoupe and DOSBox with the Game Blaster option.
Thanks in advance,
