Complex Sample & Hold and Waveform Generator with Noise Source

SSH is a random voltage generator and wave shaper. This S&H has a built in LFO and noise source, allowing for stepped and slewed random waveforms to be generated without any patching or external modules. The stepped S&H waveform can be accessed directly from the STEP output jack, or the waveform can be run through an "intelligent" slew limiter, which allows for smooth slewing between steps. The on-board slew limiter is equipped with a shaping circuit, which allows for the slew to vary between the classic R-C type of glide and linear glide. SSH features some other unique functions, which allow for an amazing variety of waveforms to be generated.

  • On-board LFO with voltage controlled rate, normalized to the sample & hold trigger generator. External triggering input jack as well.

  • Sample & hold generator is normalized to an internal white noise source, allowing for "random" stepped waveforms to be generated. External signals between +/-8V can be sampled using the EXT input jack. Stepped S&H output can be accessed using STEP output jack.

  • Separate output for slewed S&H waveform. (SLEW) Slew amount is voltage controlled. Slope of the slewing is voltage controlled and can be varied between a classic RC glide and linear glide. Using the RISE/BOTH/FALL switch, slew can be active when the S&H waveform is rising, falling, or can be always active (switch in middle position)

  • SLOPE can be controlled using external CVs. If the SLOPE input is fed a negative voltage, then the slope of the output waveform becomes 0 (A horizontal line), and the voltage is held at the last S&H voltage until the SLOPE CV becomes positive again. For example, if a +/-5vpp square wave were fed into the SLOPE CV input, and the SLOPE CV knob were slowly turned from 0 to max, while the square wave input is less than 0V, the SLOPE output will be held at it's last value, the positive half of the square would determine the slope of the output waveform. The "pause" feature is only available when in SYM mode.

  • Symmetry control switch - By using the SYM/ASM switch, slew slope can be "opposite" on rising and falling waveforms. If the SYM mode is selected, the slope of the slewed waveform will correspond to the SLOPE CV controls. If ASM is selected, when the slewed waveform is rising, the current SLOPE setting will be applied. When falling, the "opposite" SLOPE setting will be applied. This allows for RC or linear curves to be applied when the S&H waveform is rising, and the opposite curve to be applied when falling, which allows for unique output waveforms to be created. A rear panel header provides separate 5V RISE and FALL gate signals.

This module is 10HP and packs a sophisticated sample & hold generator, waveshaper, and noise source into a compact module.
