Neutron Sound Digital oscillator

This is the DIY Orgone accumulator, it can be built from board/panel or a kit. there is now also a separate 4u/banana version by Craig Lee http://clsound.com/orgoneaccumulato.html

The orgone accumulator got it's name from a Hawkwind song, as well as poking fun at pseudoscience.

The code is open source, available on github. https://github.com/jakplugg/neutron-sound

The output sample rate is ~50,000 hz, there are up to 12 simultaneously calculated oscillators (depending on FX mode etc).

the output is 16 bit, and the waves are 512 point 16 bit. there is an analog fixed 19khz 4 pole filter.

The 1v/octave input is "real time" exponential converted every 300-450nS, no look up tables or silly pitch bend schemes. the resolution is 1/72 of a semitone.

the detuning is modulate-able, not only the frequency (which in normal mode can be an octave) but the amount via the detune enable buttons and the position. dynamic detuning is not something i have seen used much in synths, it is quite powerful.

I have called the modulation controls FREQ and INDEX, even though when not in FM mode that is not strictly true, but they do more or less the same thing. frequency and depth of modulation.

position, detune, index, and mod frequency all have analog attenuverter inputs, as well as the respective knobs

Either an on-board 12V -> 5V regulator can be used, or the module can draw from the system 5V rail. Power draw is also influenced by op-amp choice. With system 5V used, LME49740 U3 OPA2277 U4 it is 37mA on -12V, 39mA on +12V.
