MALSTRÖM SYNTHESIZER305
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.
Controlling playback of the graintable
Each oscillator features three controls that determine how the loaded graintables are played back. These are: The
“Index” slider, the “Motion” knob and the “Shift” knob.
D The Index slider sets the playback starting point in the graintable.
By dragging the slider, you set which index point in the graintable should be played first when the Malström re-
ceives a Note On message. Playback will then continue to the next index point according to the active graintable.
With the slider all the way to the left, the first segment in the graintable is also the one that will be played back first.
! Note that the Malström’s Graintables are not all of the same length, and that the range for the Index slider (0-
127) does not reflect the actual length of the graintables. I.e. regardless of whether a graintable contains 3 or
333 grains, the Index slider will always span the entire graintable even though the slider range says 0-127.
D The Motion knob controls how fast the Malström should move forward to play the next segment in the graint-
able, according to its motion pattern (see below).
If the knob is kept in the middle position the speed of motion is the normal default. Turning the knob to the left
slows it down and turning it to the right results in higher speed. If the knob is set all the way to the left, there will
be no motion at all, which means that the initial segment, as set with the Index slider, will play over and over as a
static waveform.
D The Shift knob changes the timbre of the sound (the formant spectrum).
What it actually does is change the pitch of a segment up or down by re-sampling. However, since the pitch you
hear is independent of the actual pitch of the graintable (see above), pitch-shifting a segment instead means that
more or less of the segment waveform will be played back, resulting in a change of harmonic content and timbre.
