Arpology 

 

A 4‐voice arpeggiating synth, with an auto‐improvisation feature. 

 
 
 

How to use: 

 

1)

 

Press a piano key and Arpolgy will play a 4-voice appegiating 
pattern based on what note you are pressing. 

 
  2) To shift the keyboard up an octave 

tap

 the right button. 

     To shift the keyboard down an octave 

tap

 the left button. 

 
  3)  Arpology uses two separate User Interface (U/I) "frames."  A U/I 

frame determines which parameters are controlled by the onboard 
pots.  The two U/I frames for Arpology are: 

 
              1) The Envelope Frame (BLUE LED is on) 
 
                   Top    Pot controls envelope attack 
                   Bottom Pot controls envelope decay/sustain.  
 
              2) The Arpeggiator Frame (RED LED is on) 
 
                   Top    Pot selects arpeggiation pattern. 
                   Bottom Pot controls arpeggiation rate.  
 
  4) To switch between U/I frames, 

press

 the left or right buttons. 

     

Pressing

 the right button selects the Envelope Frame. 

     

Pressing

 the left  button selects the Arpeggiator Frame. 

 
  5)  To activate the automatic improvisor 

double-tap

 the left button. 

      Arpology now "plays itself."  The LED for the current frame will 

begin flashing, indicating that the auto-improvisor is on.  While 
the auto-improvisor is on, Arpology will not respond to key 
presses.  To turn off the auto-improviser 

double-tap

 the left 

button again.
