叠加&失谐（Stacking & Detuning） ——Smearing and pulsating

Detune：音高偏移（失谐）也会产生一定的合奏的感觉，或者描述为酒吧音乐（honky tonk）略微走音的风格。

Super-saw：很多Sawtooth Detune后叠在一起的音色

Ultra-saw：stacked and detuned sawtooth waves（这个功能在Arturia的合成器中常会出现，还有Metalizer这类功能）

Pitch：音高调节

    1. Oct：八度音高

    2. Note：半音音高

    3. Fine：音高微调

上面有个Fine tune旋钮，用于轻微的改变音高

这样就可以产生这种失谐的感觉；需要注意的是，

当只调节其中一个振荡器1 cent，另一个不改变音高，则会出现类似镶边（flanger）的效果

有时，还会有一个OSC start按钮，可以改变声音音头的感觉，打开后会产生一个类似“特”的短促的音头

但是当使用了AMP Envelope（ADSR）以后或者Filter Envelope的Attack都会影响到OSC start造成的音头的声音是否出现

由于使用的是Doubling，所以两个振荡器的波形要是一样的

①有的合成器只有一个Detuning旋钮

②Bass的声音一般要稳定，有支撑的感觉，所以不宜使用Detuning。

在频率的调节上通常有如下选项

octave / coarse

semitone / tune / transpose

cent / fine tune / detune

p.s.在图中，在低于原始频率的87 Hz基频下存在次谐波（subharmonic），基频衰减，二次谐波幅度增加。

-Two oscs. fine tune osc1 up by few cents(X), osc2 down by a few cents(-X)(d -x must have opposite directions, and must be equal numbers). Then change to 50/50 and play note.

-This is called detuning which gives a smearing, pulsating effect.

-Greater the # of cents(x and -x) is, the faster/more intense the vibration etuned note is.

-Hard rule to detuning: X and -x must have opposite directions, and must be l numbers.

-The exception to rule: Detuning one osc by 1 cent while leaving other one gives flanging effect.

-Both oscs need to have same waveform and pulse width. Mix knob should be

-Oscillator start button is a control related to detuning and doubling

-When oscstart button is on while detuning/doubling, you will get a sharp inty attack transient(tkkkk sound at beggining of note)

-on also gives you consistent pulsation(Same pulsate sound for every note ay. Especially noticeble when you use 1 cent flanging effect)

-When oscstart button is off while detuning/doubling, you will only get a and soft attack transient

-off also gives you varying pulsation(Each note sounds different sort of like ndom knob in serum)

Slyenth: Set voice of an osc to 2, then turn detune knob and stereo knob to ge amount of detune and stereo width.

If stereo is lower, means there will be pulsation. If high is no

ion. Retritg is same as start button

in syntorial. If retrig on there is atk transient, if no there is ake sound more noticable.
