  1. Tiny PCM Synth View File I wanted to explore the possibilities with the PCM output. This tiny synth generates a sweet tone from three sine waves, coated in a thin shiny silver layer of aliasing. To spice it up, I also added a delay effect. You can play it with your keyboard. Use Z and X to switch octaves. I do not plan to follow this route any further, because the possibilities are quite limited with the X16. I am sure one could do better than I did, but the X16 doesn't have enough power to provide a whole lot of flexibility in the sound generation (at least with PCM).

  3. Hi everyone, in my current project, I would like to detect key releases, or at the very least if any keys are pressed, at all. The usual GETIN only returns a nonzero value one single time during a key press (except the repeated ones when the key is held down for a longer time). It doesn't provide any precise information on HOW LONG the key is held down. Are you aware of any possibilities to get more precise (and possibly more low-level) data from the keyboard? Thanks in advance. Edit I've found this thread where they mention, that keyboard input is handled by the NMI handler. Since both the ISR vector, and the routine itself are in ROM, there is no way to get the actual data from the keyboard (without modifying the ROM). I really think that the X16 would greatly benefit from a more exposed keyboard interface.
  4. Just a thought I've had: I'm currently developing on Windows 10, and if I were either a contributor to a github project or using modern tools, I'd benefit from access to the X16's PETSCII Keyboard plugged into the computer while coding or developing. Would this be possible under the current design? Would it require special drivers or application? I believe a lot of hardship can be eliminated by allowing the keyboard to work on modern systems in any case. And with less hardship, more software. Example: Plug in the X16's Keyboard into my W10 System <Punch The Keys, For Gods' Sake!> Get PETSCII Characters just like I would natively.
