The System X S/H Noise is a sample and hold/noise module based on the Roland 100M 150 module. As well as sample and hold – and both white and pink noise – it includes some nifty additional features not found on the original:
- A 2 input CV mixer, with each channel having its own attenuator. This enables you to mix a couple of different CV sources to get some really complex S/H modulations. The idea for this is ‘stolen’ from the ARP Odyssey’s S/H mixer, though the implementation uses the CV mixer circuit from the Roland 100M 132 module. White and pink noise are normalised to the two CV inputs, so they will feed the S/H circuit unless an external source is connected to these sockets.
- Gated Lag: The stock 150 module had lag/ slew/ glide which was set manually. This module goes one better by making the lag gated, so you can use an external pulse wave to turn it on and off. When no source is present at the lag input, lag reverts to being set manually. The implementation is based on the way in which Roland implemented this feature for their MC202/ TB303 units.
