[sdiy] TI SN74LS624N, worth buying?

[James Patchell]

Uh....I would pass.  They aren't very good VCO's.  Not really directly 
musically usefull.  I have never used the LS624, but I did use the S124 
way back when.  It is a dual VCO, but the problem I had with these is 
that the coupling between them made them difficult to work with.  I 
ended up just disabling one of the VCO's.  But they do work at very high 
frequencies.  I am sure somebody probably could come up with something 
creative, but in general, I would save my money.
