I don’t think (or expect) that Syntakt simply loads M:Cycles sysex but maybe Elektron could have a little online converter - from reading the manual I’m pretty sure the parameters of the six machines are the same as their counterparts on the Cycles, but extended. Sure, there is an additional Amp envelope and a filter but I’m guessing that if you don’t use those, the machines should sound pretty much the same.
Pure speculation of course, I don’t even own a Syntakt (yet).
