Changelog MK3

 (PCB 3.0)

The circuit has been redone almost from scratch (again) to fix 
an issue with the 2.0 PCB LFO, but also to add a couple of new
features. It has a few more components than the 2.0 PCB, but
is still a straight forward build. :)

New feature: NAND modulation. XOR (ringmod) modulation 
was added in the 2.0 version of the PCB. The 3.0 version also 
adds NAND modulation for a different flavour. Both these 
settings are modulating oscillator 1 (against oscillator 2).

New feature: Manual stepping of the sequencer. Now you can 
push a momentary button to manually toggle through the 
steps of the sequencer when the LFO is off. If the button is 
pressed while the LFO is on, it will temporarily stop the 
sequencer.

While turning off the LFO, it will also stop on the current 
sequencer step (unlike the old versions which always went 
back to the first step) so that it's easier to tune each step of 
the sequencer.

Notes

The Quantum Defrakulator output is meant to hook up to an 
amplifier like a guitar amp or through a mixer to a PA system.

It can't drive a speaker directly. If you want to drive a speaker you will 
need to add an amplifier at the output, such as a LM386 or similar. 
There's plenty of simple 9v amplifier projects around if you do a 
search. :-)
