Malström Synthesizer

121

The Oscillator section

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

erators, 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 gener-

ate 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 select a graintable for one or both of the oscillators.

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

top left corner.

When an oscillator is activated, the button is lit.

An activated oscillator

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 grainta-

bles.

The graintables are sorted alphabetically into a number of descriptive cate-

gories, 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”.

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 key-

board at 440 Hz.

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

The range is -12 – 0 – +12, thus equalling one full octave down or up.

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.
