4ms Quad Pingable LFO
Four tap-tempo LFOs with voltage-controlled waveform skew
12 HP Eurorack module
Four independent LFO channels with tap-tempo rate setting. Each channel's rate is set by "pinging" — sending a clock pulse or tapping the Ping button defines the LFO period. Skew morphs the output waveform continuously from ramp-up through triangle to ramp-down. Channels are color-coded (red, black, blue, green) and can be individually enabled or disabled. CV inputs allow external modulation of waveform skew and phase reset per channel.
