Verbos Electronics Voltage Multistage 16 modulator-eurorack-modules an audio interface or aVerbos Electronics Voltage Multistage 16 has gate ins on all the stages and in the analog address mode, it triggers the ramp every time you change stages, so it can do Subotnick type things while totally off the grid. In theory, a sophisticated enough control voltage source can replace all of the control voltage sources in a modular system. That includes saw, square, pulse, triangle LFOs, AR, AD, ADSR, multistage envelopes, tracking generators,
