[. . . ] Chapter 2: Your First Session with the QuadraSynth. This section provides a brief tour of the QuadraSynth, shows you how to audition the various sounds of the QuadraSynth, and points out the various performance features. Details rear panel connections (like MIDI, footpedals and the optical digital interface), proper hook-up procedures, plus application examples. Covers the structure of sound sources within the QuadraSynth, how to read and navigate through the LCD display pages, how to edit parameters, and how to store edited Programs, Mixes and Effects. [. . . ] Example: Use this modulation source to obtain a different sound in the upper and lower keyboard ranges. Velocity relates to how fast a key goes from the key up (note off) to the key down (note on) position, and therefore represents the dynamics of your playing. Release velocity relates to how fast a key goes from the key down (note on) to the key up (note off) position. Example: Use this to affect the level of a sounds release based on how fast you remove your fingers from the keys. 68 QuadraSynth Reference Manual Editing Programs Aftertouch Pressing on the keys after theyre down generates this control signal. Aftertouch is also called channel pressure, and represents an average of all keys being pressed. This affects any keys that are held down. The harder you press on the keys, the greater the degree of modulation. Polyphonic Pressure This is similar to aftertouch, but each key can respond to individual pressure messages. Although the QuadraSynth keyboard does not generate poly pressure, the sound generators can respond to poly pressure signals entering via the MIDI In. Example: Assign poly pressure to the sounds amplitude in a string ensemble patch. You can then increase the level of selected notes of a held chord to pull some notes out of the chord. You can find out more about these parameters and how they affect the sound in their respective sections (e. g. , to find out how Pitch Envelope Attack affects the sound, see page 74 on Pitch Envelopes).

Higher positive values increase the amount of modulation. Negative values also increase the amount of modulation, but with negative phase (i. e. , if the modulation would normally be increasing with depth set to a positive number, the modulation would instead be decreasing at that same moment had the depth been set to a negative number). Gate Mode (Off or On) When Gate Mode is on, the selected Modulator will only be routed while notes are being played. In other words, you can gate the effect of the Modulator so that it stops when you are not playing any notes. This can be used on sounds with medium to long release times, where an interesting effect (like tremolo) is intended to be active while holding notes down, but deactivated as the sound is fading away after being released. 70 QuadraSynth Reference Manual Editing Programs Pitch LFO (Page 1) The Pitch LFO is most often used to apply vibrato to a sound. 7 The following Pitch LFO variables will make a difference in the sound only if the PITCH LFO DEPTH (on Page 2 of the PITCH function) is set to a value other than 0, or, if the Pitch LFO is a source in the MOD function. Wave (7 choices) The waveform determines the shape of the LFO. Use Quad Knob [1] to select either Sine, Triangle, Square, Up Saw, Down Saw, Random or Noise. SINE TRIANGLE SQUARE UP SAW DOWN SAW RANDOM NOISE Speed (00 to 99) Quad Knob [2] controls the speed or rate of the LFO. For fast modulation, increase this value. For slower modulation, decrease this value. Delay (00 to 99) This is the amount of time that is to occur before the LFO kicks in. Sometimes, it is desirable to have modulation come in a moment or two after a note has been played, rather than starting instantly. The higher the value, the slower the LFO kicks in. +99 0 -99 TIME Trigger (Mono, Poly, Key Mono, or Key Poly) The Trigger parameter determines how the LFO should be triggered, or started. [. . . ] Sending a Program Change command from a sequencer or other MIDI keyboard can change synth patches automatically. There are 128 Program Change command numbers. Also note that not all units number programs consistently. Some number them as 000-127, others as 001-128, and still others arrange programs in banks of 8 programs (such as A1-A8, B1-B8, C1-C8, etc. ). [. . . ]
