I do really like Bloom, but some people have experienced issues so take a look at forums before making the leap. There is a huge selection of sequencers so a different one may be a better fit for you.
The consensus to everybody getting into modular is that you should expect your system to be a lot bigger than you originally intended. Get a bigger case than you think you need. Start with just a few modules... Learn them... THEN you'll know what could be added to make the music/noise you want. Plan to add a module or two a month. Good luck.
Check out Ricky Tines on YouTube. He's got some very inspiring Palette systems.
I like noodling with these small systems so I came up with another one that would be fun for me:
