Editing on the JD-990

"Shown is an edit screen from the JD-990. This is the "structure" page, which determines how the processing blocks are to be organized in a given patch. The ability to do this is one of the improvements that the JD-990 has over the JD-800; the JD-800's processing architecture is fixed in the configuration shown on the left side. On the right side, we see a ring-modulation type patch. Tone C goes through a TVA (equivalent to a VCA), and then is multiplied by tone D. (The "R" in the box represents ring modulation, which is implemented in the digital realm by simple multiplication of the individual samples from each input. Ring modulation is one of the few synth functions that is difficult to do well in analog circuitry, but trivially easy to do in digital synthesis.) The patch then passes through two TVFs (equivalent to VCFs), and a final TVA to shape the output." click here for the full post on Sequence 15.

  1. Looks essentially like the D50/550 and Fantom Series.

  4. I think that Matrixsynth knows how much pukey digital green appeals to nerds from the pre-red and pre-blue LCD screen era.

  5. bingo tyler. That and green is my favorite color. Here's some ugly retro from '97 for you: Matrixsynth Old (still retro in '97).

    dave, yep, it sure looks nice on the site.
