Noddy Holder

author: Sean Bechhofer (github.com/seanbechhofer) date: 2022-03-26 labels: gates, sample&hold, track&hold

Cum On Feel the Noize! Two channels of sample/track and hold based on a single trigger and CV source.

Digital in is a gate, Analog in is arbitrary CV.

Output 1 is the original gate, Output 2 is S&H based on gate and CV, Ouput 3 is T&H based on gate and CV.

Outputs 4, 5 and 6 are similar, but with the gate inverted.

Basic Usage

1. Switch on
2. Connect outputs to modules
3. Send gate and CV to inputs
4. Send resulting gates and CV to modules

Details

Sample & Hold: When gate goes HIGH, CV is sampled, and the resulting value is output until the gate goes HIGH again and we re-sample.

Track & Hold: When gate is HIGH, CV input is mirrored to the output. When gate goes LOW, CV is sampled and the resulting value is output until the gate goes HIGH again.
