Or does that need to happen<br class="">inside the plug-in code?<br class=""><br class="">And what about more advanced parameter display, e.g. a wet/dry setting,<br class="">which I want to display as going from 100:00 through 50:50 to 0:100, but<br class="">the actual parameter value is just 0.0..1.0 (or -1.0..+1.0)?<br class=""><br class=""><br class="">Background: I'm trying to improve the JX10.ttl from the mda.lv2<br class="">collection [1], so that the parameter display in the LV2 host generated<br class="">plug-in UI is more useful and intuitive, i.e. instead of e.g. the slider<br class="">for OSC Tuning being going from 0.0 .. 1.0, I want it to be displayed as<br class="">-24 .. +24 cents.
