At first glance, SP2 has a conventional subtractive synthesizer structure 
with an 

oscillator

 producing a harmonic-rich waveform (PULSE) fed 

thru a 

filter

 that takes away some of the harmonics to shape the timbre 

and finally an 

envelope

 that controls the loudness of the output thru 

a VCA (voltage controlled amplifier).

The deeper you delve into the SP2 architecture, the more clearly you will 
see the internal routing; and by fiddling with the MOD faders, you will 
uncover an unconventional synth-creature with unique behaviors. This 
architecture, including internal routings and normalizations, is illustrated 
on the front-facing side panel.

The envelope is normalized to the CUTOFF MOD, so you can use it to 
control the timbre of the filter by bringing up the CUTOFF MOD fader.

The envelope also triggers the Sample & Hold circuit that generates 
pseudo-random voltages that can be used to control the pitch of the 
oscillator via the PITCH MOD fader. Therefore, each time you trigger the 
envelope (either by pressing the TRIG button, cycling it with the CYCLE 
switch, or triggering it from the sequencer), it will trigger the Sample & 
Hold and can add randomness to the melody. The more you push the 
PITCH MOD fader up, the more pronounced the effect will be.

We suggest you get to know the behaviors and interactions described 
above before engaging the sequencer. There is a lot to explore!
