Meetup founder Mark Mosher will be presenting “Subtractive Synthesis with Elektron Analog Four and Overbridge”. If you are just starting out - this talk will give you a nice overview of subtractive synthesis that can be applied to any subtractive. For more seasoned synthesist - this talk will show off some unique sounds & features of the amazing Analog Four and illustrate how you can use Overbridge (with a touch screen) to integrate the Analog Four with your computer and DAW. Member Brian Horsfield will finish up the presentation with a comparison of Analog Four MKI vs MKII.

I invite members with Elektron Analog Four MKI or MKIIs to bring their instrument along so after the talk and during mingling people can give this wonderful synth a try.

*** If you are willing to bring your Analog Four, post a note in the "Comments" section below the invite description on and let me know if your bringing a MKI, MKII, or Analog Keys. ***

This presentation will be followed by a collaborative performance by The Aefonic (aka Brian Horsfield) and NewEcho (aka Mark Mosher) using only Elektron Analog Four MKI and MKII.

Everyone bring headphones.

The Aefonic

Brian Horsfield (The Aefonic) has been composing and playing electronic music since the 1980s. Originally hailing from the North of England but now a 20 year Boulder resident, musical influences include iconic Manchester bands such as Joy Division, New Order and The Smiths. A long time synthesizer aficionado, Brian recently lost his battle to avoid a slippery decent in modular synthesis and now spends most of his time pouring over expensive modules connected by wires.
