I am using mtpro2 lite and I have the following issue when using the PARENS command, here is the minimal example
\documentclass[12pt]{article}
\usepackage{amsmath, amsfonts, amsthm, amssymb,fancyhdr,graphicx}
\usepackage[utf8]{inputenc}
\usepackage[spanish,es-nolayout]{babel}
\usepackage{csquotes}
\usepackage[paper=a4paper,
verbose=true,
total={170mm,257mm},includefoot,includehead
,nomarginpar,
]{geometry}
\usepackage{textcomp}
\usepackage{times}
\usepackage[scaled=0.92]{helvet}
\usepackage[lite]{mtpro2}
\usepackage{fix-cm,multicol}
\usepackage{enumerate}
\newtheoremstyle{Solus}%
{\topsep}
{\topsep}
{\sffamily}
{0pt}
{\bfseries}{:}
{ }
{}%
\theoremstyle{Solus}
\newtheorem*{solu}{Solución}
\begin{document}
\begin{solu}
Primero debemos encontrar el dominio de $Y$, en este caso
\begin{align*}
Y=\ln\PARENS{{a^{|K|}}} \text{ PARENS}\\
=\ln\left(a^{|K|}\right) \text{ left( right)}\\
=\ln\LEFTRIGHT(){a^{|K|}} \text{ LEFTRIGHT()}
\end{align*}
\end{solu}
\end{document}
the result is the following
I rather like the second option since the argument of \ln is align with the baseline. Is there a way to ensure this behavior with PARENS and LEFTRIGHT?
