fultonbot Posted December 14, 2020 Share Posted December 14, 2020 (edited) I don't know if this is useful to anyone else, but I built a tool to help me figure out what pokey sounds on the 7800 It lets me test out sound mixing on all four channels at the same time. Controls: -Joystick/arrow keys select the value to change (orange) -Left button increases value, right button decreases value - F = Frequency -W =Waveform -V = Volume (needs to be > 0 to hear anything) -D = Duration (how many frames to play the sound) -S = Silence (amount of time between plays to keep channel silent) -T = Type (C)onstant (play at same volume), (A)attack (play from volume 0 to 15, (D)ecay (play from volume 15 to 0) This is s the first version. Suggestions much appreciated. link: JS7800: Atari 7800 Emulator (raz0red.github.io) There may well already be a tool like this, but this is mine. I used to help me understand the pokey chip and what it can do. I think I probably made something similar to this in Atari 8-bit BASIC back in the 1984 or 1985 for the same purpose. pokeyplayer2.bas.a78 pokeyplayer2.bas.bin Edited December 14, 2020 by fultonbot 5 1 Quote Link to comment Share on other sites More sharing options...
