Simple Custom Posts per Page (SCPP) allows to configure the number of posts displayed for every custom post registered in WordPress.
See <a href="https://wordpress.org/extend/plugins/simple-custom-posts-per-page/screenshots/" rel="ugc">Screenshots</a> to known why it is called “Simple”.
In your Readme page in Setting tab of WordPress, it adds an option for every post type.
Disable Plugin in Template: 
You can disable plugin filters in your template whenever you want. Maybe you need a query with a different number of custom posts per page for a specific post type. 
Using this code before your query, the filter plugin will be disabled for a specific post type:
<pre><code><?php $GLOBALS['ado_cspp_disable']="YOUR_TYPE"; ?>
</code></pre>
With this code, you can use your personalized query for your loop.
