You're the modular man around here, Chysn. I respect your knowledge and I will take a look at Intellijel.
Another issue with the modular approach is that I don't want to spend months and months trying to get an instrument to a fairly completed and playable state. That's why Pittsburg Modular has interested me, with their small but complete systems, especially the Lifeforms SV-1. The hardwired module approach has the advantage of always providing a complete and useable instrument, so that adding to it usually means doubling the size of the whole instrument. With adding Odysseys, SEMs, or Lifeforms, from day one you've got a instrument that's ready to make music.
Do you have experience with Pittsburg Modular? There aren't many YT demonstrations of there instruments available, and certainly not musical ones, so it's a bit like shooting in the dark.
