Xewton Music Studio Documentation

		Puts the effect into the FX bus, meaning that it will be applied only to those tracks which have FX enabled (blue FX icon in the mixer's track list). All the other effects are still applied to all tracks after the FX effects are processed. The image below illustrates the bus structure:
		Each effect is calculated only once. The effect's FX switch controls which bus it acts on. The amplifier effect acts on each track before they are mixed (pre-fader). Simply put, first the amplifier is applied, then all FX effects are applied to all FX tracks, this is mixed with all the other tracks, then all remaining effects are applied, the result is mixed with the no-FX tracks and put through the limiter.

7.1.3 Preview button

Identically to the instrument tab's preview button,
it plays one or more notes (alternating) with the current instrument.

7.1.4 Default button

Resets the current effect's settings to the preset values.

7.2 Effects

7.2.1 Volume

7.2.1.1 Master Gain

This is not the device gain, instead it controls the gain of the internal limiter.

High values can lead to unwanted distortion, low values may not produce the desired volume.
Different volumes may be required depending on your output route
(the device's internal speaker, or earphones, or loudspeakers).

In technical terms, this setting is required because if all playing instruments are mixed (added up),
the resulting values will in most cases be way outside the range +/-32768 (the 16 bit border) and clipping would occur.
The limiter uses a smooth mathematical function (curve) to compress larger numbers into the 16 bit range.
The master gain slider controls the slope of this curve.

7.2.1.2 Device Volume

Brings up a popup with a slider which has the same function as the iPhone's hardware volume buttons.

If you output through the iPhone's internal speaker (not recommended), be shure not to turn it all the way up. If you connected external speakers, set this slider to maximum and control the volume via the speaker's volume controls for the best audio quality.

7.2.1.3 Decibel Meters

Indicates the current output level for each of the stereo channels.

7.2.2 Reverb

Reverb gives the illusion of a sound space by repeating the original sound in predefined time intervals with certain gains. In technical terms, the reverb is calculated with predefined, filtered delay lines.

7.2.2.1 Reverb Style

Selects the type of reverb (room, hall, canyon) which is defined by the time interval and gain of the delay lines.

7.2.2.2 Reverb Size

Controls the size of the sound space. In larger spaces, the time interval between the delays is longer.

7.2.2.3 Reverb Brightness

Low brightness gives the impression of a darker room, while maximum brightness leaves the reverb unfiltered.

7.2.3 Delay

A delay repeats the original sound in a certain time interval set by the timing buttons/switch and the song tempo. The result is then fed back into the delay, resulting in many repititions.

7.2.3.1 Timing Buttons

The selected note length will define the time interval of the delay, together with the song tempo.

7.2.3.2 Timing Switch

Dotted timing is 50% longer, Triplet timing means 33% shorter.

7.2.3.3 Feedback

Controls the gain of the feedback. Low values will limit the effect to a one audible repitition, high values will make the total delay duration very long.

7.2.4 Equalizer

The 3-band equalizer has fixed frequencies at 800Hz and 5kHz. Tap or move anywhere in the 3 areas to set the gain of bass, middle and treble tones. The range is -10dB to +10dB, the volume is automatically adapted to avoid clipping.

7.2.5 Amplifier

The amplifier simulates overdrive by clipping the sound with a mathematical function (curve).

7.2.5.1 Overdrive

Controls the amount of distortion, i.e. the input gain for the amplifier.

7.2.5.2 Style

Changes the mathematical curve, resulting in a different tone.
