Transistors are usually matched on Vbe.

That said, transistors /from the same batch/ that are close in Hfe are
probably
close in other specs as well. So yes, you might get away with checking Hfe.

I did just that building the Yusynth Minimoog clone and it sounds great and
even tracks well enough. That might also be plain good fortune though ;)
