Jena is a digital module that may be used as a flexible waveshaper for CV and audio signals, a wavetable oscillator, a Walsh function generator, or a rhythm generator. Jena is a new member of the Leibniz Binary Subsystem which operates on signals and volt- ages by manipulating binary 8-bit numbers. The Leibniz subsystem offers direct access to all individual bits of data which can be mixed and cross-patched (like in the popular circuit bending experimental technique, but without the risk of damaging your device). Please note that for analog inputs and outputs it needs to be paired with other Leibniz modules, such as Drezno. Complex chains will be possible as more components are added to the system. For example, you can use two Lipsk expanders (one before Jena, and another one after Jena in the chain) for unlimited patching.The main purpose of Jena is to map incoming digital data to some other digital data through a transfer function selected from its waveform shape bank. For example, Jena may be connected in a loopback to a Drezno module so as to transform input analog wave- forms to some other output analog wave- forms via the ADC and DAC sections in Drezno.Jena allows one to waveshape signals through the classic table look-up technique: input 8-bit values are treated as arguments of a function stored in memory and values read from suc- cessive locations in memory are passed to the output. You can also feed a simple saw- tooth or a triangle wave from your VCO and it will be transformed into variety of wave- shapes (from 11 wavetable banks) with the additional option of through-zero (DX-style) phase modulation. The shape of the wave may be also morphed with the panel knob and/or external CV. Individual bit outputs on Jena may also be used to produce interesting signals. There is a dedicated bank of Walsh functions that can be used for an unusual twist on additive synthesis. Also, transforming slow waveforms to sequences of binary signals using the individual bit outputs is a great way to create rhythmic drum patterns. Jena comes with a special bank of 256 modern drum loops split to individual voice triggers.
