If you start entering a number and change your mind, wait a few seconds and the QuadraSynth will revert to the previous Mix number. After switching between the Preset and User banks, press Quad Button [1] to see the name of the Mix in the display again. However, there is much more about a Mix that may be edited. Refer to Chapter 5 for more about Mix editing. If you do, you will be kicked out of Mix Edit mode and will select another Mix, losing your changes.
When enabled, the Channel number will appear in the top left of the display. Use Quad Knob [1] to adjust the level. Changes to Mix parameters are temporary and will be lost if another Mix is selected. To make changes permanent, you must store the Mix into the User bank.
Refer to Chapter 4 for information about storing changes. Each Program and Mix uses one of the Effects Patches to enhance the sound. While the Program remembers which Effect Patch to use, and how much sound to send to it and to which of the four effects buses , all Effects Patch editing is done outside of the Program in Effects Edit Mode see Chapter 6. In a Mix, you can combine several Programs, and use one of the Effects Patches.
All the Programs can use this one Effects Patch or bypass it. Also, each Program in the Mix can either retain its own effects settings send level and bus , or you can override and reroute them with the Mix Mode effects settings.
The display will change to Program Edit mode. The last function and page selected will be shown in the display. To get back to the first function, simultaneously press both. Changes to Program parameters are temporary and will be lost if another Program is selected. To make changes permanent, you must store the Program into the User bank.
Each Program can use up to four sounds, for either layering or splitting the keyboard. Each of these sounds has its own effects , as well as effects bus assignment. Many of the Programs in the QuadraSynth use only one or two sound layers, while others may use all four sounds.
This is where you determine how much level will be sent from the current Program sound layer to the effects processor, and on which of the four busses. To enable a sound, hold down its respective Quad Button i.
MIDI is an internationally-accepted protocol that allows musical-related data to be conveyed from one device to another.
The MIDI connections provide three different functions. In Mix mode, however, the keyboard can transmit on as many as 16 MIDI channels, each with its own keyboard range for more information on Program mode and Mix mode, see Chapter 4. Caution: Do not attempt to connect more than three or four units together using thru connections as this may impede the MIDI data flow to the connected devices. Depending on the capabilities of your MIDI controller keyboard, you have two different options available for how the S4 will respond when it is in Mix mode:.
To create layers or stacks, your controller must send multiple MIDI messages to the S4 simultaneously. This offers you the added control of changing the sound from the controller by sending Program Change commands on individual channels within a mix. A disadvantage of this approach is that the controller must send many channels of duplicate MIDI messages simultaneously. On playback, the sequencer sends this data back into the QuadraSynth, which then serves as a multitimbral sound module Mix mode.
The sequencer can generate data over several channels; in Mix mode, the QuadraSynth can be programmed so that individual Programs play sequenced data on specific channels. Example: If the sequencer transmits a piano part over channel 1, a bass part over channel 2, and a drum part over channel 10, you could set up a QuadraSynth Mix so that a piano sound plays only the MIDI data assigned to channel 1, a bass sound plays only the MIDI data assigned to channel 2, and drums play only the MIDI data assigned to channel The QuadraSynth can store up to User Mixes.
This allows the QuadraSynth to send data to the sequencer for recording, and play back data from the sequencer. You need to determine which way is best for your application. This is a way of verifying that the sequencer is set to receive properly. For more information, see page See page for more information. Each pedal can be assigned to independent modulation functions within a program. Example: One pedal could control volume, and the other vibrato depth.
This provides the same function as the sustain or damper pedal on a standard keyboard. You can use either a normally closed or normally open momentary contact footswitch. Plug it into the rear panel SUSTAIN footswitch jack before powering up the QuadraSynth; on power up, it will automatically sense the footswitch polarity and calibrate itself accordingly. If your footswitch seems to respond backwards notes sustain unless the footswitch is pressed , turn off the QuadraSynth, make sure the footswitch plug is fully inserted into the footswitch jack, then turn the power back on.
The QuadraSynth can send digital audio directly into ADAT, which provides better fidelity than using the analog inputs and outputs. Fiber optic cables of various lengths are available from your Alesis dealer. The shorter the cable, the better. The model OC cable is 5 meters long and is the maximum length recommended.
Remove the two pieces of clear plastic, tubular sleeving if present that protect the tips of the optical cable plug. To test the cable and QuadraSynth digital output, plug one cable end into the QuadraSynth.
The other end should emit a soft red light it is not dangerous to look directly at this light. Once the fiber optic connection is made between the QuadraSynth and ADAT or an AI-1, the QuadraSynth will output audio on the first four channels of the digital bus the bus is capable of handling eight channels of digital audio.
The Main Left and Right outputs are routed to channels 1 and 2, while the Aux Left and Right outputs are routed to channels 3 and 4.
Note that the volume knob controls the level of all analog and digital output channels simultaneously. Set the volume to maximum for most applications. For more information about using the 48 kHz clock, see page in Chapter 8. The QuadraSynth contains digitized acoustic and electronic samples , organized into 16 banks of sound groups.
The banks are:. Several functions filter, amplitude envelope, pitch envelope, LFO, multiple modulation sources, signal processors, etc. A Sound is the combination of a sample with its associated processing. A Program consists of up to four sounds. These sounds can be layered, split over specific keyboard ranges, or selectively overlapped. The QuadraSynth has User Programs that you can modify and Preset Programs that are permanently installed in the QuadraSynth at the factory although the Preset Programs can be edited, they must be stored into the User bank to permanently retain your changes.
Note that each Effects Patch has its own memory location, apart from the Programs and Mixes. This location can have the same number as the Program being effected, or the Program can select an Effect Patch in a different location. Example: Suppose Effect Patch location holds a nice, clean room reverb sound that you want to use on several different Programs. The Effect Patch itself must be saved.
This is extremely useful for multitimbral setups where the QuadraSynth plays back different sounds on different MIDI channels. Because of the 64 voices and built-in effects, the QuadraSynth is often the only sound generator needed. The QuadraSynth provides voice polyphony i. If a program uses one sound, up to 64 notes can play at once. Layering two sounds allows for note polyphony and layering four sounds, note polyphony.
Layering is a powerful technique that allows you to build up complex timbres. This is crucial because acoustic instruments have extremely complex, evolving sounds. Being able to layer up to four sounds allows for creating large ensembles e.
When creating layered Programs, keep polyphony in mind. If all Programs in a Mix use all four available sounds, the QuadraSynth will quickly run out of voices. The QuadraSynth is always in one of two main modes: Program mode or Mix mode.
Here are descriptions of these modes:. Initially, both the Preset and the User Programs contain data loaded in at the factory.
The User Programs can be edited or replaced with your own Programs. In some cases, the Program is heavily dependent on its effect; in others, the effect is more subtle.
Therefore, much thicker and richly textured sounds can be created. In Mix mode, the QuadraSynth can be used in a wide range of applications. It can be used for live performance, in which sounds are layered or assigned to sections of the keyboard. It can also be used as a multitimbral sound source for desktop music and home studio applications. In Program Edit mode, you can change the various settings which determine the sound of an individual Program, or create an entirely new Program from scratch.
In Program Edit mode you can:. Mix Edit mode lets you change the parameters of an existing Mix. Up to 16 Programs can be active in each Mix, and Mix Edit mode sets up how each will be played. Mix Edit mode allows you to:. Effects Edit mode is used for setting up the Digital Signal Processing effects. Each Effect Patch has 4 effect bus inputs, and an internal configuration of multiple effects such as reverb, delay, and pitch-related effects chorus, flange, etc.
You can determine what kinds of effects are used on each bus, change parameters such as reverb decay time or chorus speed of effects, set modulation such as having the modulation wheel change the delay time , and set the effects mix how much reverb, delay and chorus on the output of each effect bus. Use Global Edit mode to set various parameters which effect the entire instrument, such as overall master tuning, display contrast, MIDI controller settings, keyboard sensitivity, and how the unit will respond to or generate messages during Mix mode.
Note: This illustration shows all display flags turned on at once. Actual displays show only some of these at any time. When Edit 4 mode is selected press [EDIT 4] , all four numbers appear, to indicate that all four sounds are available for simultaneous editing Edit 4 mode is available in Program Edit mode only. Displays the various editing functions available in a particular editing mode.
When a function is chosen, the page number strip and right-hand side of the display will show values related to that function. Only the functions used by the current edit mode will be displayed and selectable. Some functions have too many options to fit on a single screen. These functions use multiple screens, with each screen considered a page. This strip shows which page is selected by underlining the page number. When in Mix mode, the name of the currently selected Mix will appear here.
Likewise, when in Program mode, the name of the currently selected Program will appear here. This line is used to show the labels of the bar graph meters, which determine the functions of the four Quad Knobs and Buttons. These labels change depending on which function and page is currently selected. The labels are abbreviations of the parameters; the complete name and value of a selected parameter will appear in the Name strip.
Note: Not all four Quad Knobs are active in all pages. In Mix mode, they are used to select one of the 16 Programs for viewing and editing. The Quad Knobs have two editing modes: Immediate and Pass-thru. When using the Quad Knobs to adjust parameter values, you may prefer using one mode over the other.
Mix parameters edit a Mix. Program parameters edit a Program. Effects parameters can be edited from within a Mix or a Program see below. Global parameters edit general characteristics that affect the entire instrument. The selected function will be underlined in the display. There can be up to four editable parameters on a page. Turning a Quad Knob or pressing its Button selects the associated parameter for editing. The currently selected parameter is indicated by a thick line at the bottom of one of the four bar graph meters.
With bipolar values that can go positive or negative, turning a knob clockwise increases the column height upward from the midpoint, and turning a knob counterclockwise increases the column height downward more negative value from the midpoint. Always refer to the parameter name strip in the display above the bargraphs for the current parameter label and value.
Feel free to make changes and twist dials; these will not be made permanent unless you store the Program described later.
Pressing this button toggles between Program Edit mode and Effects Edit mode. As you select the different edit Functions, the page number strip shows how many pages exist for that function, and the right part of the display will show the parameters on the current page.
Some functions have more parameters than will fit on a single display page, and therefore will have multiple pages, as indicated in the lower left corner of the display. A Program is made up of four sounds. Other times, you may want to edit one variable in all four layers for example, the attack parameter of each layer. The only difference between the two modes is what variables will appear in the display at the same time.
Programs or the Effects Patch. So keep in mind that when you edit an Effects Patch, it may affect the sound of any other Mixes that also use it. View the discussion thread. Alesis QS8 Tuning Model?
