I tend to do 4 songs per bank, with 1 part per song. I use mostly static slots with sample chains, that gives a lot of flexibility on the fly to change sounds around when writing/performing.

That's how I do it, one song per part, so 4 per bank. It depends how complex your songs are though. Some of my songs, just for convenience, extend to a second part. It's still lots and lots of songs. ... And yes, 4 songs per bank is the most convenient way to work. With song 1 on patterns A1 to A4, with part 1, song 2 on patterns A5 to A8 with part 2, and so on.

I tend to see Parts as "songs" or ideas, and Patterns as variations within a song. One cool trick I like to try when I need inspiration is to load a project with lots of patterns and parts, load up a random pattern, and assign a different part to it than the original one. Instant guaranteed fun!

I think it would work well if you use a bank per song and within that song use 4 different parts (if needed). I usually end up maxing out the memory of my flex sample slots before I can use all the banks in a project. So, if you think of having 16 different songs or compositions per project that could really utilize the parts efficiently and give you tons of room for flex slots. You could also use 2 songs per bank and then have 2 parts per song would probably be plenty as well. But, honestly I would only use one or two "Sets" on the entire OT. Once you start putting all sorts of samples in different sets, they become unusable in situations where you might want to use a sample from a different set. Ya dig?

The way I use it is that each BANK is a SONG. So 16 patterns for each SONG. (16 patterns shared across 4 Parts)

While progressing through the SONG, I will come to a point where I have used all the TRACKS in that PART. So I will move on to the next PART and continue on a different section of the SONG.

I prefer to choose this way and keep things simple and lately I have been sampling everything into the OT, so I can perform these SONGS on one box.

If then I want to work on one of the ideas, I would go to that BANK and start making few patterns for each of the 4 PARTs.

Also when I am building a tune in a BANK, I would limit myself to use PART1 for the first 4 patterns, PART 2 for the second 4 patterns and so on...Of course I would be copying and pasting parts in between and make alterations to them

I tend to think of each bank as a "song". So per song I have 16 patterns and 4 sample setups (parts).

So a single project gets 16 banks/songs, each with 16 patterns, 4 parts each with 16 scenes.

For live use, i do 4 patterns per bank, with A1 Part 1, A5 Part 2 and so on. I consider each pattern as a song.

I'd recommend patterns to structure the time line and scenes for main automations (rise etc.).

Before elektron, I preferred to use 16 bar loops. In my opinion, 16 bars are the perfect unit to structure electronic music, e.g., 1x (or 2x, but that doesn't make much difference here) 16 bars intro, 1x 16 bars theme1, 1x 16 bars some more action, 1x 16 bars theme2 etc. with some cymbal hit in the beginning of every 16 bars and some BD/SD variation in the end. With the elektrons, I switched down to their 4 bars. This seemed quite restrictive to me. Sometimes I tried to go back to 16 bars via pattern chaining, but that's not the same (for instance, because you can't easily copy&paste between different patterns during playback and need a large amount of patterns).
