You can get mark I version for free two posts below.
Some of new features of mark II version:
- algorithmic mode, makes it possible to playback or loop sequences of random events,
- music box, tunes melodic samples to defined pattern, to create melody sequences,
- reworked and expanded sound banks, including third tonal bank to use for generating melodies,
- saving and loading presets, presets can then be sequenced in meta-sequencer, to create tracks inside the machine, preset-set can be then saved to file,
- automated effects rack.
Rhythm patterns were partly programmed by hand and party shuffled by the machine. Melody lines were applied entirely by machine's looped randomizers.
You can find detailed description in the manual.
To see how it works look at videos in previous post.
Psychodrumma mark II is available at Sampleism.
Note, you need full version of Native Instruments Kontakt 4 or newer to make it work. It won't work properly in Kontakt Player. Also, as it's written in KSP script, it is quite impossible to import it to any other sampler.
