Tutorial I: Create your own Scale in Learn Mode using the knobs 

Creating your own scale is easy. With the 

Ensemble Oscillator

, the process of creating a new scale is called “Learning”. 

There are two ways to do it: with the knobs, or with an external CV and gate source. This tutorial covers the former. 

1. Start by unpatching all cables except the 

Out

 jack(s), and turning down 

Twist

Warp

Detune, 

and 

Cross FM. 

 

2. Turn down 

Balance

 so that you're just hearing the root oscillator. Turn up 

Pitch

 and/or 

Root

 

so that it's playing a low frequency. This is your root note. 

3. Flip the 

Scale 

switch to 

Free 

and turn the 

Scale 

knob to a scale you don't mind overwriting 

(you can restore it later). 

4. Tap the 

Learn 

button. It’ll turn red to show you're in Learn mode. 

5. Hold down the 

Learn 

button and turn the 

Add Note 

(

Root

) knob. You'll hear the original root 

note plus a new note whose pitch you're controlling. The new note will be higher or lower in 

pitch depending on which way you turn the knob. Keep turning the 

Add Note

 knob until you 

like how the two notes sound together. Release the 

Learn

 button. 

6. Repeat the last step to add another note. You should be hearing three notes now. 
7. Let’s try adjusting the pitch of the last note you added. Hold down 

Learn

 and turn the 

Fine 

Tune 

(

Pitch

) knob. The pitch of the last note will change by a small amount. 

8. Repeat the 

Learn + 

Add Note

 step again to add a fourth note. This time, make the pitch 

obnoxiously high. 

9. Oops! That last note is a mistake, let's get rid of it. Tap the 

Delete Note

 (

Freeze

) button and 

it'll go away. 

10. Add some more notes if you wish (maximum of 16). 
11. When you're done, tap the 

Learn 

button. It’ll flash green to indicate your scale saved. 

12. That’s it! You've programmed a scale. It's saved in the group and slot the 

Scale

 knob and 

switch point to. You can recall it even after you power down. 

13. Let’s listen to the notes of the scale. Notice that the 

Freeze 

button is flashing (see inset 

below). Turn the 

Root

 knob up and/or down until the 

Freeze

 button flashes green. Now you 

can slowly turn 

Root

 to play the notes of the scale in order. 

14. Listen to how the notes sound together as a chord or waveform by turning 

Balance

 up 

towards center, and adjusting 

Spread 

and 

Detune

 until you hear a full sound.  

15. Feel free to play with 

Twist, Warp

, and Cross

 FM 

to find a timbre you like. 

16. If you want to restore the original factory scale into the slot, make sure the 

Scale

 knob is 

pointing to the slot you want to restore and the 

Scale 

switch is selecting the correct group. 

Then hold down the 

Learn 

button for about four seconds. The button will flash blue and the 

sound will change when the original factory scale is restored. There is no undo for this.

Why is the 

Freeze

 button flashing? 

When you exit Learn mode, the 

Freeze

 button will often be flashing. This is telling 

you that one or more of the knobs have their values "frozen" until you turn the knob 

back to where it was when you first entered Learn mode (it also could mean you 

adjusted a Shift feature). To “unfreeze” a knob, turn it up and down until the 

Freeze

 

button flashes green. The sound won’t change until it’s back in its original position. If 

more knobs still need unfreezing, 

Freeze

 will keep flashing. When exiting Learn 

mode, you usually want to unfreeze 

Root

 and 

Pitch

. This feature keeps the pitch 

from jumping drastically when you exit Learn mode, and means you don’t have to 

retune to external equipment.
