mLab ONKEL SEM Synthesizer Expander Module

Individual item (proto type) € 1.800,- made in Germany by mLab.midisoft.de

The ONKEL SEM Synthesizer Expander Module is a modular synthesizer module that is quite versatile and packed with features.

ONKEL SEM offers flexibility with various inputs and controls for frequency, pulse width, and modulation. The inclusion of OSC 2 HardSync offers interesting sound design possibilities.

The VCF/VCA/MIXER section features multiple sources and modulation options for shaping the sound. The resonance and filter frequency controls allow an extreme range of sound design, while the three envelope section provides dynamic control over the VCO, VCF, and VCA.

The LFO section provides additional modulation options with two outputs and controls for waveform, frequency, and amount of modulation. The inclusion of a MIDI IN controller for Note number and Pitch bend is also a great feature for incorporating external sources into the modular setup.

Overall, this module is a powerful and versatile tool for sound synthesis and experimentation.
