My first experience of sample and hold within modular and I’ve been spoilt! Two input mixer taking CV and/or audio internal clock and external syncing with white and pink noise on board. Plus an additional lag circuit with a gated on/off. Feature packed module that’s all nicely spaced and very playabale to getting your hands in and messing around. It also makes a very good audio processor a mixer, with noise and downsampling bit crusher style when at audio rates.
