Knob Acceleration
Due to the enormously flexible nature of Solaris’s design,
there are often times when the physical knobs will control
parameters with greatly differing value ranges. For ex-
ample, the 4th knob in the Oscillators section controls the
oscillator frequency either in semitones (-60 to +60), MIDI
clock divisions, or absolute frequency, from 0Hz to 20kHz.
A sort of “acceleration” scheme has been implemented that
ensures the user is able to interact with a given parameter
in a way that makes the most sense for the parameter--pro-
viding fine adjustment for an LFO’s rate, for example--while
still allowing the full range of values to be accessed without
endlessly turning the knob. In order to accomplish this,
several default knob behaviors have been developed. For
example, the range of the Cutoff frequency of a filter is 10
octaves 6 semitones. This is listed in the Cutoff parameter
as 0.0 to 126 semitones. The default knob behavior ap-
plied to Cutoff is to increase or decrease the frequency by
1 semitone as the knob is turned. There is a small amount
of acceleration programmed in, to ensure the entire range
is available with only a couple of full turns. In this case, the
default knob behavior is to compress the range of values,
which allows faster access to the range of values, but by
making larger “steps” along the way. In contrast, the LFO
Rate parameter uses the opposite scheme. In order to al-
low fine adjustment of LFO Rate, the knob is programmed
to increase or decrease in steps of 1/100th of 1Hz as the
knob is turned. Clearly, this scheme would require many full
rotations of the knob to reach 500Hz.
Knob Acceleration and the Shift Button
Pressing and holding down the Shift button as you turn a
knob will invert its default acceleration scheme. Holding
down the Shift button while turning the LFO Rate knob will
cause the value to jump by 1Hz, making it much quicker to
access values at either end of the range. The exact oppo-
site happens for Cutoff, allowing for very fine control over
the frequency.
The
Data Wheel
is not affected by the
Shift
button.
It always scrolls at the finest resolution available for
the parameter.
