Toppobrillo - Sport Modulator (B-Stock)

B-Stock unit with signs of usage. Power cable, screws and washers are included. Comes without original packaging.

Dual voltage controlled lag/portamento, Sample and Hold, staircase wave generator or a LFO module. Inspired by Serge´s Stepped and Smoothed Generator (SSG). A pretty complex module.

each section can be either:

• A VC lag that can be made to hold-state on command.
• A wide-range VC linear triangle LFO that ranges from around 500-600 Hz to 30 seconds (or so) per cycle, when put into cycle mode.
• A sample and hold with controllable input slew [or sample 'correlation' ] the control input is the same. ['S/H' in the drawing].

When cycle is selected in Hold mode, the section will generate complex staircase waveforms that are synced to input pulses. [by the way the input signal doesn't have to be a pulse, but just about any rising slope, this was done to allow for even more inter-compatibility between the 2 sections.].
Finally, the unlabeled jack in the middle is a gate output that compares the top section's output with the bottom. This was heavily inspired by the Serge 'smooth/stepped generator' but expands on it by offering dual mode operation, much wider control range and improved functionality. If the top section is more positive than the bottom one, the output goes high.
