  • • Sample & Hold, Filtering of CV signals

Video clips

Audio examples

The Volt SH-1 is a control voltage (CV) sampling and filtering unit. With it you can sample a signal at any rate, any resolution, hold the value for any duration, and even sample the signal asynchronously with a gate trigger input. The signal can also be low pass, high pass and band pass filtered before or after sampling.

Product details

Available in a bundle with the Volt CB-1 and Volt SL-1

Sample and Hold

This unit enables you to sample the input signal at a user defined rate, holding the CV value for a specified duration. The rate can also be synced to the tempo for creative rhythmic effects. Finally, you can even trigger your samples at any time with an external CV signal.


If you want to adjust you modulation signals live, switching from harsh brutal variations to soft oscillations, or add some interesting side oscillations, this is the tool. The Volt SH-1 lets you filter your signal with the classing low pass, high pass and band pass modes with resonance.

Separate Rise and Fall filtering

Sculpt your CV signals with separate filter settings for ascending and descending signal fronts. Less classic is the possibility of having different filter settings between signal rises and signal falls. Use this to keep sharp rises while creating slow releases in your signal or add resonance only when the signal decreases for “whobbling” and “bouncing” modulations.


Of course, all the front knobs and buttons can be fully automated inside your song tracks and the Sample and Hold unit can be controlled by a dedicated “Gate” CV. You decide when you want the sampling to take place.

Release 1.0.1

This version corrects some minor glitches in the SH-1 - The device name sticker is now visible when the SH-1 is combined. - The filter does not show a slight "overshoot" anymore when resonance is set to 0. This is really nice if you want to create some smooth glissando effects.

Release 1.0.5

This version fixes a bug with an incorrect filter cutoff value when changing Reason 7 audio output sample rates.
