Yes, in ten days it's three years. I only could imagine, that one or more main developers lost interest. It's a pity, because I like lmms. It's one of the open source daws, which work a bit like FL Studio, pattern based.
Personally I'd best like to work with something like the sequencer of the Elektron products, but in software. Finding creativity in limitation these things a thought out.
Currently I tried out Stochas, using Reaper just as a plugin host. This works well for me and Stochas is also open source, maintained by the great team around surge synth.
I never get used to these session managers, like externally usable with Carla etc. I'd best like Stochas stand-alone as Plugin host. I miss the simplicity of lmms.
