sqsl Nashville App-Analysen für 9. Dezember

sqsl Nashville is a MIDI controller/tool for exploring harmonies, modes, and chord progressions within heptatonic scales. Concept When we press a key on a traditional MIDI keyboard/piano, we are saying: "play a specific note (pitch/frequency)". When we press a "key" in the Nashville app, we are saying "play a chord shape from this degree of the currently selected scale". The played chord shape is defined as a set of degree offset(s) from the played degree. Examples 1/ If the scale is set to C Major and the chord shape is set to be 3 notes (1, 3, 5), playing keys 1 to 7 would result in C Major's triads (CEG, DFA, EGB, FAC, GBD, ACE, BDF). 2/ If the scale is set to C Major and the chord shape is set to be a single note (1), playing keys 1 to 7 would simply play the 7 notes of the C Major scale (CDEFGAB). 3/ If the scale is set to C Major and the chord shape is set to be a single note (2), playing keys 1 to 7 would play the notes of the C Major scale but shifted by one degree (DEFGABC). Setting the scale Scales in Nashville are set using 3 parameters: - Scale pattern: semitone distance (interval) pattern - Mode: rotation of the scale pattern, defining which member of the scale pattern is used as the start point - Root note: which absolute note (pitch) is used as the start point for the rotated scale pattern Examples 1/ We select Diatonic as our scale pattern—meaning we want to work with the interval pattern 2-2-1-2-2-2-1 (or whole, whole, half, whole, whole, whole, half). We select the first Mode (I), which means we will not rotate the scale pattern, and we select C as the root note. We have set the scale C-D-E-F-G-A-B—usually called the C Major scale. 2/ We select Diatonic again (2-2-1-2-2-2-1) but now we select the third Mode (III)—the pattern is rotated by two steps, so we get 1-2-2-2-1-2-2. Selecting C as the root will result in this scale: C-C#-D#-F-G-G#-A#. A very different set of pitches from C Major but related, as it originates from the same scale pattern. Usage (example) - Trigger notes/degrees in the PLAY section, capture them in a loop (REC), and modify the pattern, root, mode, and chord shape to explore variations. - Looped data can evolve – timing and degrees are randomly recombined at the end of each loop, and the chord shape can also be selected randomly. Using with MIDI keyboard - White keys always trigger degrees of currently selected scale (chord shapes are ignored) - Black keys are used to change the scale on the fly - Press C# and following key will set Root - Press D# and following black key will set Scale Pattern - Press D# and following white key will set Mode - F#, G#, A# keys are used as 3 positions where 3 scales can be stored and recalled (long press = store, short press = recall) Notes - Settings and loops are saved automatically but there is no preset system - App runs in the background - Only standalone (no AUv3 support) - Does not produce any sound of its own (only MIDI notes) - More details at https://www.seqsual.com
