MOS Technology TED

also called 7360/8360, TED stands for Text Editing Device. it's both a video and audio chip of Commodore budget computers, like Plus/4 and 16.

its audio portion is pretty barren - only 2 channels. one can output square wave and other may be either square or noise. pitch range is limited as well, akin to that of SN76489, and volume control is global.

effects

none so far.

info

this chip uses the TED instrument editor.

chip config

the following options are available in the Chip Manager window:

  • Clock rate: sets the rate at which the chip will run.
  • Global parameter priority: change the priority of macros which control global parameters, such as volume.
    • Left to right: process channels from 1 to 3. the last one to run macros will take effect.
    • Last used channel: process channels from oldest to newest (since last note). the one which had the latest note on will take a effect.
