Additionally, the following global settings are saved whenever a setting slot is saved:

Custom scales

Slider LED mode

The six Settings Slots are represented by the six Lock buttons. When you enter System Mode, the Lock buttons will flash in a 
way to tell you their status:

Dimly flashing: Settings Slot is empty

Brightly flashing: Settings Slot is full

Lit solidly (not flashing): Settings Slot is currently selected

Recall Settings

To recall settings from a Slot, enter System Mode and then tap one of the brightly flashing Lock buttons. The settings from 
that Slot will be loaded and you will instantly exit System Mode.

Saving Settings

To save the current settings into a Slot, enter System Mode and then hold down one of the Lock buttons for three seconds. 
The SMR will beep for a fraction of a second. The next time you power the SMR on, it will boot into the last saved Slot. 
Recalling a slot and then saving it is the way to set a default startup slot without changing any settings.

Table of Scales and Banks

See Scales and Banks section, and ROTATE (SCALE) knob section (page 10) for details on how to change scales and 
banks. The order of the banks is this table is left to right, then top to bottom.

1. Western scale (white)

Just intonation. Each scale contains 
a root note and one interval, 
repeated over 10 octaves. Each 
scale uses a different interval (m2 to 
M7) and spans 27.5Hz to 15kHz

2. Indian pentatonic (green)

Scales 1-8 have five notes per 
octave, spanning four octaves. Each 
is one octave above the previous. 
Scales 9-11 contain selected notes.

3. Alpha scale, selected notes

 

(lavender)

.

 Each scale contains 

intervals from Wendy Carlos's micro-
tonal scale, spanning roughly from 
20Hz to 20kHz

4. Alpha scale, selected notes

 

(cyan)

More variations. All intervals 

are multiples of 78.0 cents (perfect 
fifth split into nine equal parts), so 
there are no octaves, yet rich 
harmonies. 

5. Gamma scale, selected 
notes (orange)

Each scale contains intervals 
selected from Wendy Carlos's non-
octave repeating Gamma scale, 
spanning roughly 20Hz to 20kHz.

6. 17-note per octave (yellow)

The first scale starts at 13.75Hz and 
each note is equally tempered to a 
17-note octave. Each scale is one 
octave above the previous.

7. Chromatic (purple)

The first scale starts at E2 (82.4Hz) 
and each note is one semi-tone 
above the previous. Each scale 
spans an octave and a half and is 
six semi-tones above the previous.

8. Diatonic 1/2 (magenta)

Each scale is a diatonic scale 
spanning almost three octaves. The 
first two scales start on A, the next 
two start on A#, then B, C, C#, D. In 
each pair, the second scale is two 
octaves above the first.

9. Diatonic 2/2 (rose)

Continuation of previous bank, 
starting at D#, E, F, F#, G, G#

10. Western dual-interval (light 
green).

 Each scale starts on G1 

(49Hz), followed by two intervals. 
The triad is repeated across seven 
octaves, an octave higher each time. 
The pair of intervals varies per scale: 
M2/P5, M3/flat5, m3/M5, M4/P5, 
m3/#5, P4/P5, M3/M6, m3/flat6, 
M3/#5, m3/m7, P5/M7

11. Mesopotamian (Red)

Various ancient scales from 
Mesopotamia. Scales 1, 3, 5, 7, 9, 
and 11 have six notes starting on A2 
(55Hz), and then repeats over 3 
octaves. The remaining scales are 
copies of the previous scale, but 
three octaves higher. 

12. Shrutis, Indian scales 
(Yellow-green).

 

Uses 20 notes 

from a 22-note octave, so each 
scale spans one octave and is one 
octave higher than the previous 
scale.

13. Graphic EQ (blue)

These are common frequencies in 
Eqs. The first scale is 20Hz, 40, 60, 
80, 100, 150, 250, 350, 500, 630, 
800, 1k, 1.3k, 1.6k, 2k, 
2.6k,3.5k,5k,8k,10k. Each scale is 
the same as the previous scale, 
shifted up about 3%

14. Gamelan (azure)

Scales 1 and 2 are the Gamelan 
Pelog (5-note) scale repeated over 4 
octaves. Scales 3, 4, and 5 are 
Slendro (7-note) scales spanning 3 
octaves each. Scales 6-11 are a 
selection of five notes from the 
Slendro scale.

15. Bohlen-Pierce (Lime)

Instead of octaves, the BP scale is 
based on the tritave (triple the root 
frequency), with thirteen notes per 
tritave. Each scale starts on C1 and 
contains four selected notes per 
tritave, spanning five tritaves

16. Custom scales (gray/pearl)

These are user-programmable 
scales. See section above for how to 
write and save your own scales. By 
default, they are chromatic scales
