Studio Electronics ATC-1X - Manual (Page 11)

The oscillators are the unmodified building
blocks of Analog synthesis. An oscillator
produces periodic or regularly repeating
waveforms, i.e. pitched sounds. The tuning
controls alter the frequency or pitch of the
oscillators. The waveshape selectors determine
the harmonic spectrum of the signal, its basic
timbre, or tone color.
The
ATC-X 1 has two oscillators that each
produce three waveforms. All the waveforms are
continuously being generated, so they are
available to be outputted either individually or
simultaneously, depending upon how they are selected.
What the Switch pads do:
Selects the triangle waveform. Press once to display current patch setting then
press again to turn on or off. Triangle shaped waveforms produce smooth flute-
like tones (same for both oscillators).
Selects the sawtooth waveform. Press once to display current patch setting then
press again to turn on or off. Sawtooth shaped waveforms produce punchy brass-
like tones (same for both oscillators).
Selects the square waveform. Pressing will display the current pulse width
setting: use the encoder to edit. A true square wave will be obtained by setting
the pulse width at 60
60. Square shaped waveforms produce bright reed-like tones
(same for both oscillators).
Selects Oscillator 1 coarse-tuning. Provides continuous tuning of Oscillator 1;
raises or lowers the pitch in half-step increments. 0
0 is the lowest tuning, with
multiples of 12 being the octave intervals.
Selects Oscillator 2 tuning. Pressing once will select coarse tuning; pressing
again will select the fine-tuning. Continuous presses will toggle between coarse
and fine. Slightly detuning Oscillator 2 will add warmth and depth to the sound.
