Was in somewhat similar position. The synth I liked most in the past was my Yamaha qy70. It was small & portable and I could use it everywhere. Few years ago started DAW'ing. Don't like being behind a computer.Enter Teenage Engineering. I do everything with the OPxy and the OP1field. These are the size of half a laptop you can use them everywhere. Just power it on and continue on your project. I hate starting up, being bound to fixed working space, cables, ... You don't need both machines. The field is a 4 track recorder. They wanted to emulate that workflow. Everything you record on a track is as is. It's not parsmetric where you can still make adjustments to what's recorded. It has good synths. The xy is midi based sequencer. The synths are a bit less but I still get the sounds I want. My workflow is OPxy, then record to OP1f. There I add some extra sounds or beats but mainly vocals (also great vocoder).Considere it the Apple of synths : expensive, very good at what it should do in an esthetic, minimalistic aluminum design.Plenty of youtube vids out there. Found the ones by Cuckoo insightful. You can listen to some of my tracks here on soundcloud.
