I’ve had grids previously so was familiar with mlr, pages, 64fingers, polygome etc when using my PC as part of my setup. Got rid several years ago and always regretted it. In the last few months I’ve sold a lot of unused gear to be able to fund grid/ansible. I love the ansible take on sequencing that I’d seen in videos. Before I’d used Meadowphysics max4live port it looked way too complex to me. But having a play with it after I’d bought the grid let me really gel with the interface.
Circuit is still a part of my workflow for Ableton live based work and I use it mainly for sketching ideas to import into live or a a controller. It’s still a brilliant device and I will not be getting rid of it anytime soon!
With the right interface, if circuit suits you it can create some amazing stuff on the modular. Several channels of CV plus drum tracks that could be repurposed as gates (I believe, I never got round to trying that).
Andy Pidcock has some good videos on Circuit and modular, with a big emphasis on the sequencing/playing.
And Enrique Martinez has some solid review/tip videos about circuit integration.
Hope that helps a wee bit!
