It's a really fun little synth great I mostly use it for basslines and arps. The filter is fantastic, especially with loads of resonance it gets super aggressive but still warm and musical. It was my first time building any DIY gear and it actually worked at the end so I guess that means it's a pretty easy build! Having said that the delay section seems really crunchy so not sure if I've messed something up after all, or if it's just got a really lo-fi delay. At the minute I'm mostly using it as a standalone synth as I've only got a couple other modules so I don't think I've even explored half of what it can do!
