Orgone Accumulator V3 (SMD)

Wavetable blending, modulation, and effects oscillator, bonus drum voice

This is the V3 DIY Orgone accumulator, it can be built from board/panel and is now an 0805 SMD build.

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

The Orgone accumulator module is a wavetable that blends across 3 oscillator channels, each with individual waveform and effect enable. there is a global modulator, which also has selectable waveform, frequency, and modes.

modulation modes are normal (a type of sync + AM) FM, and pulsar. the modulator can be fixed, or follow the pitch input.

on top of that, there are 7 effects available that have variation via the bipolar control. (for more detail, please see the manual link at the bottom) as well as the bonus drum voice.

The code is open source, available on github.
the code is shared with the retail version.

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 range for CV control is about 4.5 octaves, with 3 octaves on the tune control, and +-2 semitones on the fine tune.

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