TIME

]

.  

 

  

 

 
 

When the last track step is set, the 

[

TIME LED

]

 will light when  the last 

step is reached. For example, if the last track step is track step 16 the 

[

TIME LED

will light when

 

the

 NEXT

    or    

BACK 

button is pressed 

and held on track step 16.

 one step.  

 

   

 

 

7.3.4.7  SETTING  

D.S.

 AND   

 

 

This feature is not yet implemented as of  v1.04 software ! 

 
The Avalon uses the musical notation 

D.C.

D.S.

, and   . The use of 

notation saves panel space and is a salute to the original TB-303 
control surface. 

D.C.

 means "from the top". This button is used to 

program the track step where you want to loop back to 

track step 1

Hence it is used to set the LAST TRACK STEP along with the TIME 
button.   is the "repeat from" sign, and 

D.S.

 means "from the sign".  

They are used to set cue points to loop a section of a track, so a track 
will loop from 

D.S.

 back to the   sign.

7.4  REALTIME MODE 

 

 

 

In REALTIME MODE track steps can be manipulated realtime by 
overriding transpose, accent, slide, and mod env. settings. 

 

7.4.1   REALTIME ACCENT & SLIDE 

 

Accent and Slide can be 

played

 to trigger accents and slides. 

 
To override pattern step data with accents and/or slides, press 

[PITCH] + [ACCENT] 

/

 [SLIDE]

. For example, to force a pattern to 

accent steps press and hold 

[PITCH] + [ACCENT]

 

 

 

 

Accent and Slide can also be 

played

 realtime to mute accents and 

slides.

7.4.2  REALTIME MOD ENV 

 
The modulation envelope can be triggered in realtime by pressing 

[PITCH] + [ENV]

.  Each time the button combination is pressed the 

modulation envelope will be triggered. 
 

 

 
To mute modulation envelope triggers to prevent it from being 
triggered press
