Lissadron contains a dedicated sound engine, so a
reset might be required. If the reset results in a
supercollider fail, just reboot the norns and it should be fine. The engine is quite heavy and takes some time for loading. Lissadron uses global clock, which requires 200424 to run.
The underlying synthesis engine is monophonic and consists of four voices, each playing in harmonic relation to the base frequency determined by the
Each voice has a plentytude of parameters that are controlled by the two meta-parameters
x1. Influence of the two meta-parameters on the sound as well as the harmonic structure of the voices are chosen at random. The powerful part of the system lies in the possibility to retrigger the randomisation by providing a different random seed. This also makes it possible to save and recall the (seemingly random) state of the system.
The integrated sequencer allows to step through random seedsm, based either on the intenal clock, or an externally provided one. By an integrated euclidean trigger-pattern distributor, a broad variety of rythms can be created.
The norns-native interface is:
K2 seed-- -- increase random seed by one K3 seed++ -- decrease random seed <shift>-K2 seed - 131 <shift>-K3 seed + 131 E1 amp -- legato E2 x0 -- meta parameter, different for each seed E3 x1 -- meta parameter, different for each seed <shift>-E1 note <shift>-E2 seq_steps <shift>-E3 seq_freq K1 <shift>
Parameters (controlled e.g. via MIDI mapping) are
amp— if 0dB, plays a continuous sound, otherwise the synth can betriggered either by (MIDI-)notes (first MIDI device) or seed changes
seed— 14bit value determining the current random seed
x0— meta-parameter (see above)
x1— meta-parameter (see above)
lazy— determines speed of parameter adaptation to a new seed
grit— overall resonance
attack— envelope attack
decay— envelope decay
seq_freq— frequency relative to clock
seq_steps— number of sequencer steps, if 1, then sequencer is turned off
seq_fill— relative density of the euclidean pattern
seq_shift— relative value determining shifting of the euclidean pattern
trigOnSeed— weather or not to trigger the envelope on seed change
Here is the current release. The dust project manager always points to the git head of the master branch, so you should be save.
