Deluge Scales & velocity (Clip/track view)

Scales

Obviously, go to Synth mode.
To changes scales :
Shift + Scale button.

The Deluge will cycle through the 7 Western-music scales: major (ionian), minor (aeolian), dorian, phrygian, lydian, mixolydian, and locrian.

Scales on the Deluge will usually contain seven different notes.

(sometimes there will be more notes - for instance, if both a major 3rd and a minor 3rd are present when entering scale mode, both will be added to the scale.)

The deluge is quite clever as it can detect if a note you entered is in the correct scale.

If not , it will try to guess where that note will be 

The root note (at every octave) is indicated, anytime that a clip is in scale mode, with its audition pad permanently illuminated.

Any change that you make to the scale while editing one clip will affect all others that are also in scale mode

If you wish to transpose a clip up or down, this can be achieved by holding down the ▼▲ knob and turning it. Doing this alone will transpose a whole octave at a time. If you wish to transpose just a semitone, then hold down the shift button as well while turning.

To sharpen or flatten a note

1. Hold the audition button.

2. Turn the select knob.

Note Velocity

This effects both synth & kits

The Deluge’s pads are not velocity-sensitive but you can still edit the velocity.

Changing velocity has the effect  of changing volume.

1. hold down the pad corresponding to a note.

2. turn the ◄► encoder. (Velocity values range between 1 and 127.)

As a matter of interest,
I think Aphex Twin uses  A-sharp Phrygain a bit,
Basically all sharps, except for B
