Another COMPLETE controller by Master Layout Designer EZB to control "the most popular VST on the Planet." It's "a virtual analog VSTi synthesizer that takes the definitions of quality and performance to a higher level. Until now only very few software synthesizers have been able to stand up to the sound quality standards of hardware synths. Sylenth1 is one that does." This layout covers all the bases and reorganized the interface of the synth to make sense in an iPad MIDI controller. Big hats off to EZB for this amazing contribution!
Be sure to check out the notes for mapping the layout to the plug, and to understand the different versions and what goes where. Enjoy!
Sylenth1 is the most popular VSTi on the planet.

First of all, lots of thanks to Lennard, the creator of Sylenth1 for explaining how I should approach this.
I created this layout, so people can COMPLETELY control their Sylenth1 with Midi Designer. However, there is something extra you need to do this time.
In order for MIDI Designer to communicate with Sylenth1 you need a MidiLearn.dat file. I prepared the MidiLearn.dat file for you. You need to replace your MidiLearn.dat file with my MidiLearn.dat file. Your MidiLearn.dat file is located in your Sylenth1 folder.
Possible locations on Windows (if you can't find MidiLearn.dat search with explorer)
C:\Program Files\Steinberg\VstPlugins\Sylenth1
C:\Program Files(x86)\Steinberg\VstPlugins\Sylenth1
C:\Program Files\VstPlugins\Sylenth1
C:\Program Files(x86)\VstPlugins\Sylenth1
Take note that the paths for the MidiLearn.dat file are different!
Location on the Mac for version 2
~/Library/Preferences/LennarDigital/Sylenth1
Location on the Mac for version 3
~/Library/Application Support/LennarDigital/Sylenth1/Config
If there are any questions or bugs let me know. Have fun everybody.
