This is what I wrote to the developers. I bought the plugin.
probably you think that most of your customers don't know electronic music, and this is very bad. Even if they can use your preset randomly to make some noise in the dance hall, I find that your plugs are nice and could be used in serious composition too. So WHY YOU DONT WRITE PARAMETERS EXPLICATIONS IN THE GLITCH MANUAL? For example, in the Granular time stretch you call "stretcher", what does GM series of control means?
Thanks for some serious support, Alessandro Ratoci.
P.S. seems that you are missing the step duration, and steps are forced to be 16th note. Pretty big limitation, is it?
I do agree that detailed descriptions of each effect are missing from the manual. I will try to add these in the near future, to better explain what everything does.
I have tried to put tool tips on almost every part of the plugin, so you can hover your mouse cursor over something for a few moments to get a basic description.
In the Stretcher effect, "GM" is "grain modulation". There is an envelope follower which follows the amplitude of the input signal, and then you can optionally modulate the grain size in sync with this. It can help to give some interesting dynamic variations in tone and character on the stretching effect. Hopefully this becomes somewhat obvious when simply playing around with the parameters for a few moments.
Either way, you should simply play around with the effects, tweak some parameters, and see what happens. If it sounds cool, then it's all good. This is an experimental glitch plugin after all, not a perfectly accurate scientific tool. It's intended that you should experiment and have fun :)
