Workshop "The art of creating analog music"

The Spain Chapter of the IEEE Circuits and Systems organizes this 4-day workshop aimed to promote analog circuit design among students and young professionals. To this aim an innovative approach is followed: using analog electronics to create music based on a hands-on Do It Yourself (DIY) philosophy. The workshop will be held at the Basic Electronics Lab of the Public University of Navarre (Los Tejos Building, First Floor) on September 17, 19, 24 and 26.

 

The workshop will be mostly practical, paying special attention to learning based on doing. For this reason, the theoretical concepts presented will be supported by simulations and well-designed hands-on experiments, leading to the creation by the attendees of a  synthesizer. The synthesizer is an instrument that was very popular in the 60s and 70s, which is responsible for generating signals and combining them in order to create a wide variety of sounds.

 

The main objectives of the workshop are:

- To introduce students to the world of analog electronics

- To apply it in the context of musical synthesis

- To provide students with the concepts and basic tools for analog design,

- To put into practice everything learned by creating a musical synthesizer.

 

There are no pre-requisites to join the workshop, although it is advisable to have a basic electronics knowledge. Registration is free, and can be done by sending an email to antonio.lopez@unavarra.es.

 

TECHNICAL PROGRAM

 

The Workshop is divided in two parts: Part I introduces theoretical aspects, which are covered in the first two sessions. Part II corresponds to two lab sessions aimed to apply the fundamental concepts acquired.

 

Part I

 

Session 1 (17 September 2019, 6PM to 9PM)

An introduction to IEEE and the IEEE CASS Spain Chapter will be made by the Chapter chair. Then the basic concepts of music and synthesis will be shown. To understand the performance of an analog synthesizer, a free application named MinimogueVA that emulates an analog synthesizer, will be used. This application can be downloaded at this URL: http://www.vst4free.com/free_vst.php?id=405


Session 2 (19 September 2019, 6PM to 9PM)

Basic concepts of analog electronics will be taught and will be put into practice using the LTSpice circuit simulator. This simulator can be downloaded at this URL: https://www.analog.com/en/design-center/design-tools-and-calculators/ltspice-simulator.html

 

 

Part II

 

Sessions 3 and 4  (24 and 26 September 2019, 6PM to 9PM)

Two lab sessions where students will have different possibilities such as simulating other different synthesizer blocks, or to weld and build their own VCO. For doing this, a Printed Circuit Board (PCB) will be given to the student. They will identify the different parts, select the components and weld them. These PCBs will have been manufactured previously. Finally, they will test the VCO using basic laboratory instrumentation.
