Besides the RYTM and A4 (which are both very good friends with my OT), I have the OT drive a Modor NF-1 and a Hypersynth Xenophone. The Xenophone is definitely a bit more compact that the very spacious NF-1 front panel, but they both sound great and integrate well. NF-1 is a digital synth with 7-stage envelopes, plenty of modulation options and a formant filter. The Xenophone is an analog mono with a fantastic filter and lots of modulation as well. Screen is real nice and it’s super quick to program. Actually, both of these synths are very quick, workflow-wise. They both compliment my modular system and really tie everything together nicely. But yeah, the OT drives them both.

I know that you have already discuss it, but with my octatrack i pair a blofeld, and I found it great, if you take a listen on colorpalette here : himo.bandcamp.com all the synths are made with a blofeld. I find it quite versatile i terms of sound palette and I don’t find complicate to dive in and it haves this multichannel option which allow you to play up to 16 different sounds at the same time!
