Toxic Biohazard - Matrix

Toxic Biohazard Matrix

The FM Matrix is where you route each oscillator to another or itself. The matrix is laid out as follows: Oscillators 1 - 6 (top to bottom) down the left, and oscillators 1 - 6 (left to right) along the top. The modulation intersections are multiplier controls (0 to 100%). To modulate the frequency of Oscillator 2 by Oscillator 1's frequency, for example, increase the value of the cell located in the 1st column and 2nd row.

Controls

• PAN: Determines where oscillators are placed in the stereo field. This control's values range from -50 (Far Left) to 00 (Dead-Center) to +50 (Far Right). To increase the value, click-and drag your mouse pointer upwards, while hovering over the pan value display. The same action, in the opposite direction, will decrease the value into the negative numbers.
  
• LEVEL: Controls how much of each oscillator's signal will be routed to the final output. For example, if you just want oscillator 1 to modulate oscillator 2, and hear the result without hearing oscillator 1, then you would turn oscillator 1's level down to 0 and turn oscillator 2's level to 100. To increase the value, click-and-drag your mouse pointer upwards, while hovering over the level value display. The same action, in the opposite direction, will decrease the value.

• LFO: This panel is where you route LFO1 and/or LFO2 to each oscillator's amplitude. It works in the same manner as the FM Matrix. For example, to route LFO1 to Oscillator 2, you would increase the value in the cell located in the 2nd column/1st row.

• Master Pitch Modulation: Working exactly like the LFO section, this allows the user to route either LFO2, the filter envelope to the Master Pitch, as well as define the pitch bend range.

Frequency ratios

Once an oscillator is set to modulate another the table below shows how to set the source (columns) oscillator's Pitch and Detune settings to achieve a particular frequency. The table shows the approximate FM Frequency Ratios (from 0.25:1 to 32:1). The first column is the frequency ratio (1:1, 2:1, 3:1, etc). The second column is the equivalent course tuning on Toxic Bio, while the 3rd column is the equivalent fine-tuning on Toxic Bio (when necessary).
