now, this is where the fun is! orca's heart has 2 mod matrixes built in for self modulation. with just a few button presses you can create some really interesting and complex sequences. to open a mod matrix press one of the 2 leftmost menu buttons. you will see a slightly highlighted area under the parameter menu buttons. each row represents a modulation source, and each column represents the parameter being modulated. create a connection by simply pressing a button - this is like a typical pin matrix, only you use buttons instead of pins.

if you send some modulation to a parameter you should see the effect it has by switching to the parameter page - the base value is shown with a bright LED and the actual value (base + modulation) is shown in a dimmer LED.

the 2 additional columns to the right can be used to switch between the 4 scales and to toggle octave transposition (which you select on the transpose page). please note that when switching between scales it will not switch if the scale is empty - this is to prevent it from being "trapped".

there are 4 snapshots available for each matrix.

as with other parameters, no rules here - just press some buttons and see/hear what happens. the 2 buttons in the left bottom corner can help with trying things - the right one generates a new random matrix, and the left one clears it.

the 2 buttons located under the mod matrix menu buttons can enable/disable the corresponding matrix. this can be an effective performance tool. and you can even perform on the matrix itself - the leftmost button in the 2nd row from the bottom enables the momentary mode where matrix buttons will be toggled only while you press.

the 2 matrixes use different mode sources, so the effect will be different as well.

matrix 1:

  • the top 4 rows are note CVs from the first 4 voices
  • rows 5 & 6 are gates from the first 2 voices
  • row 7 flips between on and off on every 2nd sequence reset

matrix 2:

  • the top 4 rows are modulation CVs - higher range than note CVs
  • rows 5 & 6 are modulation gates
  • row 7 is the same as on matrix 1
