I jumped in on Octatrack last spring. As is mentioned here it is deep and has a learning curve - but if you stick with it and work with it a little ever week or day - you’ll find everything makes a lot of sense. It’s kind of like learning all the shortcuts in a desktop app like a spredsheet. Once you do you can really fly.

Re. “I do wish I had more than 8 tracks to work with though” - I find 8 is plenty if you start to use layers. Each of the 4 Parts (which I think of as layers) is like a separate Octatrack. Each layer can have completely different track assignments and you can switch on-the-fly or you can assign layers to patterns so when you switch patterns you also switch layers.

For example you Part 1 could look like this:

[ol]
[li]Flex (recording buffer 1) - Filter - Echo Freeze Delay[/li]
[li]Flex (recording buffer 2) - Filter - Echo Freeze Delay[/li]
[li]Flex (recording buffer 3) - Filter - Echo Freeze Delay[/li]
[li]Flex (recording buffer 4) - Filter - Echo Freeze Delay[/li]
[li]Static (kick drum)- Filter - Echo Freeze Delay[/li]
[li]Pickup Machine - Chorus - Echo Freeze Delay[/li]
[li]Pickup Machine - Comb Filter - Echo Freeze Delay[/li]
[li]Master - Lo-FI - Dark Reverb[/li]
[/ol]

Part 2
[ol]
[li]Flex (recording buffer 1) - Lo-Fi- Echo Freeze Delay[/li]
[li]Flex (recording buffer 2) - Lo-Fi - Echo Freeze Delay[/li]
[li]Flex (recording buffer 3) - Chorus - Echo Freeze Delay[/li]
[li]Flex (recording buffer 4) - Comb Filter - Echo Freeze Delay[/li]
[li]Static (kick drum)- Filter - Echo Freeze Delay[/li]
[li]Static (kick drum)- Filter - Echo Freeze Delay[/li]
[li]Static (kick drum)- LoFi - Spriung Reverb[/li]
[li]Master - Filter - Echo Freeze Delay[/li]
[/ol]

Parts are a really time save in live performance because your one switch away from swapping effects rather than lots of button presses to browse and load an effect to swap it on-the-fly.

I also put this mindmap together to help guide me through the videos from one page. http://www.mindmeister.com/310663045/elektron-octatrack-video-tutorial-index
