Global

The global page controls the global properties of BLUE which are stored in each individual preset.

Global Tuning

The global tuning of BLUE. By default it is set to 440 Hz

Play Mode

Polymore than one of note can be played at once, so you can play chords
Monoonly a single note can be played at once, pressing another key stops previous note
Legatosimilar to mono but if you have a key pressed down and then press another key the note is not retriggered (i.e. envelopes don't restart and so on), and if you release this second key the pitch returns to the original note
Sequencersequencer is played (see the Sequencer page)
Arpeggiatorarpeggiator is played (see the arpeggiator page)

Unison (off, 2, 4 or 6voice)

In Unison Mode more than one voice is played when you press a key, The slider controls the detuning between these voices.

Port Mode

Portmento mode (the amount of portmento is controlled by the Port control)

Constant RateThe portmento changes at a constant rate, greater keyboard note ranges take a longer time.
Constant TimeAlways takes the same time to portmento between any notes.
Held RateSame as Constant Rate but portmento only appears if you are holding a note and then playing another.
Held TimeSame as Constant Time but portmento only appears if you are holding a note and then playing another.
Port TimeTime/rate for portmento

Bend Up

Amount the sound's up pitch is altered by the pitch bend midi controller.

Bend Down

Amount the sound's down pitch is altered by the pitch bend midi controller. First setting is as up which makes that it uses the same amount as the Bend Up setting.

Chord

The Chord memory control enables you to record chords. Up to 8 notes can be memorised and it is also saved within the preset.

Clicking the chord gives you the options:

OffChord memory is Off and has no effect.
LearnChord memory will store any 8 notes you play. First, play the root note and then the other notes of the chord.
PlayThe chord memories will be played, so if you pressed C, E & G while in chord learn mode, then press D in chord play mode, it will play the chord D, F# & A.
AltThe chords are played in normal order than in reverse order

The slider next to chord button controls the delay between the notes played, so you can create a strum type effect.

Tempo Mode

Whether the tempo is synced to the host tempo or is free.

Tempo

Tempo of BLUE either synced to the host tempo (¼ x host tempo to 4 x host tempo) or the tempo in beats per minute

Voices

The number of voices that can be played at one time, from 1 to 16. The lower you set this value, the lower the CPU usage. So if a sound needs only 8 voices you can set it to 8. Note: voices setting is not active when arpeggiator is selected.

Filter Smoothing

This is used to smooth out zipper type noise when you change the filter frequency by smoothing these changes in filter frequency over time.

Velocity Curve

Velocity curve alters the shape of the velocity, with the velocity being biased to low values for negative values, biased towards high values for positive values, and normal for 0%.

Over-sampling (off, 2x, 4x, 8x, 16x)

This sets the level of over-sampling. When it is off no over-sampling is performed. When it s at 2x the output is calculated at twice the host sample rate and when it s at 4x the output is calculated at four times the host sample rate. The higher you have over-sampling the more CPU is needed to calculate the sound.

Anti-aliasing Filter / Frequency

When over-sampling is turned on the anti-aliasing filter is used to cut out additional unwanted aliasing noise at high frequencies. The button turns it on and the slider sets the filter frequency. It depends on the oversampling / type of sound if you need this filter.

Osc Vol. Knob

This setting determines the volume range of all oscillators volume knobs. It can be set to 10dB to -30dB or 10dB to -60dB.

Osc Precision

Each oscillator can be set so they are not always in tune; they can vary in pitch over time. The Osc Precision controls sets the level of this detuning, with 100% meaning that no detuning occurs. The Prec Max / Min speeds are used to set the upper and lower period limits that the detuning occurs over.

Equalizer

BLUE has a 2 band equalizer, which alters the total output sound, the button turns it on / off and the sliders control the low frequency / boost and the high frequency / boost.

Note: keep in mind that the Equalizer can be used in a preset. If you build a new sound, check if the Equalizer is turned off.

Dry Volume / Pan

The volume and panning of the dry output. Default the Dry volume is turned to zero which saves CPU resources if the dry channel is not used in the current preset.

External Controller Setup

Here you can load / save the external (midi latching) controller setup Each preset can have its own setup, but you can use also "Global midi". This you need to select at the "Back panel" of BLUE. See manual page 54.

Note: "per preset" or "global midi" have both their own file format
