Mode Messages Channel Messages: Alesis warranty card It quadrasyhth important to register your purchase; if you have not already filled out your warranty card and mailed it back to Alesis, please take quadrasyntu time to do so now. AC Power Hookup The QuadraSynth Plus works with the voltage of the country it is shipped to either or V, quadrasybth or 60 Hzand comes with a line cord or power supply suitable for the destination to which the keyboard is shipped.

Do not operate any electrical equipment with ungrounded outlets. Alesis cannot be responsible for problems caused by using the QuadraSynth Plus or any associated equipment with improper AC wiring.

These can provide an amplification system or mixer with several different audio hookup options: Sound Cards as well, using whatever samples they wanted.

Playing the Demo Sequence The QuadraSynth Plus has a built-in demo sequence which demonstrates the wide variety of sounds this amazing instrument is capable of generating. Additionally, there are Mixes in each of the 5 Banks. Program Mode or Mix Mode. The display will change to indicate the currently selected MIDI channel.

Try out some of these functions while playing the keyboard. The sound of the effects can also change by using these controllers. The effect of these realtime controllers varies from Program to Program; Leading zeroes must be entered for Mixes 0 — 9.

Press [0] then [5] for Mix manial. If you start entering a number and change your mind, wait a few seconds and the QuadraSynth Plus will revert to the previous Mix number. Use Quad Knob [1] to adjust the level.

Changes to Mix parameters are temporary and will be lost if another Mix is selected. Each Program can use up to mznual Sounds, for either layering or splitting the keyboard. Each of these Sounds has its own effects send level and effects bus assignment. QuadraVerb 2, other keyboards and majual modules, etc.

Chapter 3 If your footswitch seems to respond backwards notes sustain unless the footswitch is pressedturn off the QuadraSynth Plus, make sure the footswitch plug is fully inserted into the footswitch jack, then turn the power back on. Quadrashnth other end should emit a soft red light it is not dangerous to look directly at this light. Programs, and the keyboard can generate up to 16 channels of MIDI data at once. Therefore, much thicker and richly textured sounds can be created.

It can be used for live performance, in which sounds are layered or quadrasynhh to sections of the keyboard. In Mix Play Mode, they are used to select one of the 16 Programs for viewing and editing. Change the parameter value.

You can edit the value either by turning the associated Quad Knob for large value changes or pressing the VALUE [ ] and [ ] buttons for smaller changes. Always refer to the parameter name strip in the display above the bargraphs for the current parameter label and value.

Quadraeynth free to make changes and twist dials; these will not be made permanent unless you store the Program described later. Notice that the manuwl of the Quad Knobs and the number of pages in a function change between Edit 1 Mode and Edit 4 Mode.

Volume, Pan and Output of a single sound. In Edit 4 Mode, the Level function has three pages: See Chapter 9 for more information on quadrazynth storage operations. Doing so will result in recalling a different Program and you will lose your changes. Or, Press any other button to cancel out of the Store operation without storing. Doing so will result in recalling a different Mix and quzdrasynth will lose your changes.

If you have edited any of the Programs in the Mix or the Effects Patch, you must store them separately. Take a note of the number.

This recalls the edit buffer in Program Mode, which is your edited Program. Use Quad Knob [2] to enter the Program number you noted in step 6. If necessary, quadrasynyh Quad Knob [1] to select a Card Bank.

If necessary, use Quad Knob [1] to select the Bank. Mix Mode is one of the most powerful features of the QuadraSynth Plus. While in Program Mode you can play only one Program at a time, in Mix Mode you can play up to 16 Programs at once, either from the keyboard as layers or splits quavrasynth from an external sequencer via 16 MIDI channels or a combination of both.

Program in the Mix. Chapter 5 changes will be lost. The same goes maunal editing the Effects, which will be stored with its associated Program. If you select another Mix before storing, your changes quacrasynth be lost. There are five Banks available in the QuadraSynth Plus. Program Number to This determines laesis Program Number — for the selected Chapter 5 AUX alesi outputs.

When set to OFF, the channel will not be sent to either set of outputs but can still feed an effect bus. A thick line will appear above any active MIDI channels as you play notes or send notes to the QuadraSynth Plus from a sequencer on those channels.

This determines whether or not the selected channel will respond to the keyboard, quadrasynht and mod wheels, foot pedals and sustain pedal of the QuadraSynth Plus itself. Range Page 3 The following four parameters determine whether or not specific types of MIDI information will be received or transmitted, and are set separately for each Channel in the Mix.

Program layer to the effects processor. The QuadraSynth Plus offers you a choice of what parameters to use for effects: Use the PAGE [ ] and [ ] buttons to position the cursor. Quad Knob [1] selects the character.

Here is a chart of available characters: Use the MIDI [ ] and [ ] buttons to hear each channel quadraasynth turn. The QuadraSynth Plus will generate MIDI messages from the keyboard, regardless of the Range settings for that channel in the Mix, but it will not play the internal sound.

Also, become familiar with the signal and modulation flow within the QuadraSynth Plus as shown in the various block diagrams included in this manual so that you can understand the many ways in which you can process a signal as it works its way from oscillator to output. The QuadraSynth Plus comes with factory preset programs, and user-editable programs. You can layer these sounds together, or divide them into regions of the keyboard, or a combination of these things.


The following diagram illustrates the signal flow within each QuadraSynth Plus Program. LFO, and other control sources described later. Note that the waveforms in the QuadraSynth Plus are different from those found in samplers or many sample-playback units. Because the QuadraSynth Plus has its own filter module and amplitude module for Program as it is raised. But in synthesizer programming, modulation is used to control even the basic characteristics of a voice: It is a complete digital signal processing unit with four input buses, simultaneous multiple effects, and flexible signal routing.

Pitch, Filter, Range, Effects Level, etc. You can use Quad Knob [4] in each Function page to select which one of the 10 drum sounds to edit. Here is a block diagram of a sound in Uqadrasynth Mode. Selects one of the available samples by name from the selected group, or OFF no sample selected. Each group has a variety of samples from mwnual you can choose, although some groups such as waves have more samples than others.

Aux outputs means that the sound will appear at only the left Aux output. The higher the number either positive or negativethe greater the amount of pitch change for a given amount of aftertouch. Chapter 6 With an exponential curve, the pitch change seems to Use 1-PITCH mode when you want a program sound layer to play a single pitch polyphonically throughout the entire keyboard range.

Aleeis negative values drive the cutoff frequency lower for a given amount of velocity. Many acoustic instruments, such as acoustic guitars, sound brighter when you play them more forcefully.

Chapter 6 positive velocity control over the filter can simulate more realistic acoustic sounds. The higher the number negative or positivethe greater the effect. Applying aftertouch with this parameter set to a positive value raises the amplitude; conversely, applying aftertouch with a negative value will make the sound softer the harder you press. This can be further enhanced in Mix Mode by using the Quadtasynth function in Mix Edit Mode to cap-off the lower and high limits.

Qaudrasynth adjusting the Sound Overlap value, you can still hear the previous note fading away after the new note has been played. It is important to note that Sound Overlap can have a negative effect on polyphony. By adjusting the Sound Overlap to a lower value, you decrease the number of voices alesiz by each new note, and thereby ensure there are voices available to play other sounds, if necessary.

Chapter 6 Velocity relates to how fast a key goes from the key up Although the QuadraSynth Plus keyboard does not generate poly pressure, the sound generators can respond to poly pressure signals entering via the MIDI In. Pitch Bend Wheel is used.

However, moving the Mod Wheel while the Quantize parameter was on would cause the pitch of a held note to rise in half-step increments.
