Available as an assembled Module and as a DIY project.
This Module is currently available.
This 12HP Eurorack module provides four separate LFO's, which each can deliver three different waveforms. Each LFO can output both a square, triangle and sine wave. The frequency of each LFO can be altered by twisting each of the corresponding knobs. While each of the four LFO's is similar in terms of design, they do operate on different frequency scales. The top LFO being the fastest and operates roughly at wavelengths between 0.1 and 5 seconds. The bottom one is the slowest and can generate wavelengths of up to 10 minutes, lending itself perfectly for the creation of slow emerging soundscapes. Due to the availability of these four distinct LFO's, this module is a great addition to almost every Eurorack setup.
