Another vote here for the Digitone - Elektrons most immediate synth (maybe ever?). My test for immediacy doesn’t equate to 1 knob per function (Juno, 101, etc all amazing ofc) but rather how easy is it to get a different sound from the current patch or “jamability” - with this test the Digitone x-y, harmonics, and feedback are all immediate and will instantly transform your sound.
I’ll add the Dominion Club for two reasons 1. It’s smaller than it’s big brother so sits “immediately” alongside anything 2. Without menu diving you can dial in a variable LP/HP/Notch Filter, blend the digital OSC, vary the digital OSC, vary the Analog OSC for instant patch transformation. And it sounds everything between chest thumping deep and head spinning mental.
