SP2 digital VCO upgrade

SP2 has officially leveled up. This free firmware update unlocks enhanced MIDI control, MIDI CC implementation,
new CV and GATE output modes, and a bunch of quality-of-life improvements. But the real big news is that the
original analog oscillator (bless its pitch-drifting soul) has gone digital. That means vastly improved tuning precision
and stability and 8 new variable waveforms to explore and run through SP2's rich and unruly analog filter and VCA.
This update requires moving a jumper on the SP2 circuit board before uploading the new firmware. See the firmware
update instructions below.

This manual covers the differences between the analog VCO firmware v1.2 and the digital VCO firmware v1.0. For
full feature functionality, please see the digital VCO reference manual:

New features of SP2 digital VCO version 1:

1.

Digital VCO

2.

Fine-tune fader mode

3.

ENV G and SLIDE G trigger/gate modes

4.

Envelope gate probability as FX8

5.

Triggered pitch change mode

6.

VCO Pitch Limiter

7.

CV pitch tracking mode

8.

MIDI clock detection

9.

FX controlled by MIDI notes

10. Envelope triggered by Note On mode
11. MIDI CC implementation
12. MIDI transpose
13. Improvements and bug fixes

New Button Combos:

SLIDE + MIDI + GATES = select waveform
SLIDE + FINE-TUNE = set waveshape
P MIDI = toggle Triggered pitch mode
MIDI + TRIG = toggle Trigger Envelope at Note On mode
TRIG + SLIDE = toggle SLIDE G trigger/gate mode
TRIG + PATTERN = toggle ENV G trigger/gate mode

Hold SCALE at power up = toggle VCO Pitch Limiter mode
Hold PATTERN at power up = toggle CV Pitch tracking mode
Hold SLIDE at power up = toggle FINE-TUNE fader function
Hold PLAY + TEMPO + TRIG at power up = factory reset
Hold SCALE + SLIDE at power up = calibration and test mode
Hold MIDI at power up = firmware update mode
