Studio Electronics Boomstar Modular Levels

LEVELS is a versatile, low-noise six channel summing mixer/attenuator for audio and CV, re-designed by Tim Caswell, which can be used rather effectively in a variety of ways: 6 in 1 out, or two separate mixers: 4 in 1 out, and 2 in 1 out, e. g., when only jacked-in to MIX 5/6 output all input channels pass through; utilizing the 1-4 OUT removes channels 1-4 from the MIX 5/6 output. Handy indeed.

The pots are wired with a logarithmic volume curve that is tuned for use with audio but it will work splendidly with CV as well. Pressing LEVELS into service as a wave-shaper by patching all of the individual OSCILLATION waveform outs (sub, sine, tri, saw, ramp, square) into CHANNEL inputs 1-6, makes for vivid beguiling shapes—a morphable hybrid waveform of your innermost sound designs. Consider pairing the two Modstar modules when building your system.
