Ribbon potentiometer diy, Make a Ribbon Controller: Ribbon controllers are a great way to control a synth. Nov 29, 2025 · Naturally, the heart of the build is a ribbon potentiometer (also known as soft pots). It’s essentially a touch sensitive strip that changes in resistance depending on where you touch it. All you need is a 500mm membrane potentiometer for position, layered with a force-sensitive resistor for pressure. A selection of Spectra Symbol SoftPots. FIGURE 2. 96mm/2. This shape is a circular soft potentiometer with a donut-shaped sensing region whose outer diameter is 55. They consist of a touch-sensitive strip that lets you control pitch continuously. Mar 30, 2016 · The whole thing is epoxied to the plastic strip, for strength. if you are interested in You’re probably familiar with linear and rotary potentiometers, but there's another variable-resistance option to consider, known as a ribbon controller, which allows you to control the pitch of an oscillator by sliding a finger up and down a pressure-sensitive conductive material. 63mm/1. The red cable is the pitch CV and the yellow cable is the gate. in the basic plan it's just a loop of ribbon wrapped around a sliding surface, with a couple of flexible wire contacts that change resistance as they get closer and I thought that I would share my DIY project. Manufactured by Spectra Symbol, these are nice little ribbon controllers (also known as 'soft potentiometers') with an adhesive backing. Oct 7, 2022 · To recap, there aren't many standalone ribbon controllers about, but they seem fairly simple to make. The electrically conductive strip called 'velostat' that responds to changes in voltage or resistance caused by… This article describes a very simple ribbon controller that uses a Spectra Symbol SoftPot ribbon potentiometer for the ribbon. After my previous project making an MIDI-to-trigger converter, I realized that I could re-use that exact same hardware for this ribbon-to-MIDI converter. I made a ribbon controller with a ribbon potentiometer. Arduino-MIDI Electronics: The ribbon is just a potentiometer -- it needs electronics to interface to a MIDI synth. A 200 mm SoftPot ribbon controller set up for pitch use and connected to a Behringer Crave analog synthesizer. These happen to have a female connector, but versions with Crimpflex solder tabs are more widely available. Jan 17, 2007 · I want to modify my MIDI keyboard to replace some of the faders with lots of ribbon controllers. I also included schematic to the little synth I use to demonstrate it. Here I show you how a ribbon controller works and discuss t. 4in. If you can This video shows my ribbon controller in action along with a bit of a description on how it works. First video of a series about building a DIY ribbon controller for a control voltage synthesizer. Jun 1, 2021 · We’ll use the SoftPot Membrane Potentiometer (ribbon sensor) and Force Sensitive Resistor (FSR) strip to create a 2-dimensional ribbon synth musical instrument!! Control the pitch with the The ribbon controller we’ll construct in this article is shown in Figure 1 connected to my Behringer Crave analog synthesizer. 2in and inner diameter is 35. A selection of standard SoftPots is shown in Figure 2. I'll post my progress here. FIGURE 1.
