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 note
parameter.
Each voice has a plentytude of parameters that are controlled by the two meta-parameters x0
and 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
