MALSTRÖM SYNTHESIZER

227

The Oscillator section

The two oscillators (osc:A and osc:B) of the Malström are the actual sound genera-

tors, and the rest of the controls are used for modulating and shaping the sound. The

oscillators actually do two things; they play a graintable and generate the pitch:

• A graintable is several short, contiguous segments of audio (see above).

• Pitch is the frequency at which the segments are played back.

When creating a Malström patch, the fundamental first building block is usually to se-

lect a graintable for one or both of the oscillators.

D To activate/deactivate an oscillator, click the On/Off button in the top

left corner.

When an oscillator is activated, the button is lit.

D To select a graintable, either use the spin controls or click directly in the

display to bring up a pop-up menu with the available graintables.

The graintables are sorted alphabetically into a number of descriptive categories,

giving a hint as to the general character of the sound. Note that the categories are

only visible in the pop-up menu, not in the display.

Setting oscillator frequency

You can change the frequency - i.e. the tuning - of each oscillator by using the three

knobs marked “Octave”, “Semi” and “Cent”.

D The Octave knob changes the frequency in steps of one full octave (12

semitones).

The range is -4 – 0 – +4 where 0 corresponds to middle “A” on your keyboard at

440 Hz.

D The Semi knob changes the frequency in steps of one semitone.

The range is 0 to +12 (one full octave up).

D The Cent knob changes the frequency in steps of cents, which are 100ths

of a semitone.

The range is -50 – 0 – +50, i.e. down or up by up to half a semitone.
