# How to replace Greek letters from mathptmx with mtpro2 lite?

The Greek letters from mathptmx are horrible, some are even identical when they shouldn't be (rho and varrho for example). I'm new to LaTeX, so as simple as this task may be, I cannot figure it out. I want to replace all the small Greek letters from mathptmx with the ones you get from mtpro2, the Lite version (except for pi), as well as the infinity-sign.

• That said, I would really recommend trying to find a ready-made solution which you like. There are other options out there and it will be much, much easier and likely much more satisfactory in terms of results to use one of those. mathptmx is not, after all, the only gave in town. – cfr Nov 18 '15 at 3:41
• Is there a reason for not simply (a) not loading the mathptmx package and (b) loading the times and mtpro2 packages instead? (Instead of loading the times package, you could also issue the directive \renewcommand\rmdefault{ptm}.) Why stop at the lowercase Greek letters? For instance, the \sum and \int symbols provided by mtpro2 are way better than the ones from mathptmx. – Mico Nov 18 '15 at 8:26
• Well, the full mtpro2 has a price of \$129 (academic). The Lite version has many limitations, and it does not work nearly as well when it comes to chemistry, or chemistry-related packages. I'm basically trying to get everything as I want it, without having to pay anything. I have already replaced the \sum, manipulated the \int, and lots of other things to my liking. The only thing remaining, really, are the lowercase Greek letters. The free mtpro2 lite version does provide those. – SuperNoob5000 Nov 18 '15 at 16:57
• @Mico Well, times.sty is deprecated. However, it isn't as though there aren't other options for Times-like configurations. @ OP Especially if you are already making changes of the kind you describe, you really should post a minimal example so we can reproduce your current font configuration. And, as I say, a link would be good. I've got a full installation of TeX Live. I have zero idea where the fonts you are referring to are. Sure, I could look it up. But, heck, I'd also have to create a document, hoping it is sufficiently similar to yours.... Life's too short. – cfr Nov 18 '15 at 22:44
