A further note about lasers. Eurorack modules are particularly though but these shiny machines are not. In other words you can break it if you doesn't care about the frequencies you feed it in, specially if you use signals with a lot of spikes or angles. I have implemented all kind of protections, but trust me, you can break it anyway so, be gentle!
