LMMS might be a meme, but it's the best meme. It's free, so that more or less puts it in it's own league. Version 1.0.3 was alright, but the current RC builts are the tits (1.2 RC3)
It's very good. Free. Gives you all the features of FL Studio for free. I recommend this for anyone into music making.
I used to make songs on this for hours when I was younger. It is a great way to start out, but it just doesn't come with enough. It is free, so I understand why it's not the best, but it is good.
FL + Ableton = LMMS... The only thing is that it doesn't have good sounding plugins but it have vst availability, so... nice in my opinion... It has both pattern editor as in FL and step sequencer as in Ableton...
LMMS or Linux Multi Media Studio is a good DAW and easy to work with and it still have access to many different types of sound and adjustments. For a beginner, i suggest you start to work with this
I just got this a few days ago and have been using it to sketch out ideas on any pc I don't have ableton on, it works with any and all vst plugins 64 or 32 bit and is very easy to use for experienced musicmakers.
