[sdiy] keyboard op amp question

[Pat Kammerer]

Hi all,

I'm getting my parts for this keyboard controller circuit;
http://www.musicfromouterspace.com/analogsynth/keybrdcontroller.html

I have one question though.  I have not been able to locate the LT1112
precision op amp, but am considering the LT1013CP instead.  Do you think
this would work okay, maybe Ray can answer that one?

Thanks,
Pat
