About John “Skippy” Lehmkuhl

I started with music at an early age – piano lessons started when I was 4 years old. Both of my parents worked in music stores all my life. I owned a MiniMoog and witnessed the introduction of the Yamaha DX-7 during my teenage years.

After graduating from the local community college, I moved to Seattle and worked at a music store as both a Yamaha Music School teacher and a sales person (both acoustic pianos and the early MIDI synthesizers). I created custom patches for my customers, and taught free synth programming lessons. My first library was a custom set of samples for the Korg DSS-1.  I even advertised in Keyboard magazine and shipped a few copies to customers across the USA!

A Korg Production specialist that I became friends with saw what I was doing and needed help, because the Korg M-1 had just been released. I became involved with Korg and I relocated to Los Angeles in 1988. Now, 28 years later, I’m still on this awesome journey of making sounds and teaching people how to communicate with electronic circuits in musical way.

This is what I was meant to do and I LOVE doing it!

The ultimate goal of PlugInGuru is to get into your hands powerful, inspiring patches for plug-ins so that you can get inspiration from having new sounds to work with – it really is that simple!

On top of this, I am committed to making unique tutorial and patch walkthru videos that will show you HOW a plug-ins works so that YOU can better understand how to get the most out of these incredible Virtual Instruments.
