Gliss Dev Diaries: Physical Models Bela Platform 2023-01-26 | In this dev diary we look at Gliss controlling Rings by Mutable Instruments. This is not the original Rings but rather a Pure Data implementation running on our Pepper module. We love Mutable Instruments and take great inspiration from their open source ethos, design philosophy and incredible synthesiser modules. We will miss them!Gliss is the perfect counterpart for complex synthesis models as you have two dimensions of highly sensitive and high resolution control literally under your fingertips, position and touch size. In the video above we are using touch size to control the Damping and Brightness parameters of the voltage-controlled resonator. The touch position on the other hand is used to control the speed at which the excitation signal is repeated. You'll hear more about Mutable Instruments and Pepper in coming weeks but for now here's a snippet for you to enjoy.

Gliss Dev Diaries: Expressive Keyboard Mode Bela Platform 2022-12-19 | These videos show the current state of the Gliss firmware and each focus on a specific mode. Please note that we are actively working on the firmware for Gliss with a group of beta testers and everything is subject to change. We welcome any feedback you have.The expressive keyboard mode transforms the touch strip into 5 pressure sensitive buttons with vibrato. Each button can be tuned to a fixed voltage. When you first touch one of the five buttons you will always be in tune and then it is possible to slide continuously between the fixed notes (performing glissandi) for violin or theremin-like performances. The great thing about this keyboard is that you always know that you'll find the in-tune note when you arrive at the centre of the next button.The vibrato amount is configurable through the submenu. Also to change the tunings of the individual button you just need to go to the submenu, select the button you want to change the tuning of, and then press and drag to retune.Help bring Gliss into the world and be one of the first to get this module by backing us on Crowd Supply: crowdsupply.com/augmented-instruments/gliss

Gliss: Modular Synth Touch Control Bela Platform 2022-11-18 | Gliss is an elegant and intuitive synthesizer module for touch control. This Eurorack module lets you draw waveforms directly into your system so you can add a human touch to your control signals. It also can act as a signal visualizer, slider, or expressive capacitive keyboard. Gliss is small but powerful (4HP), and allows you to control your signals through high-precision touch sensing. See how waves behave with descriptive and immediate visual output via LEDs mounted behind the touchplate.Find us on Crowd Supply: crowdsupply.com/augmented-instruments/gliss

Trill Craft is perfect for crafting complex interfaces from conductive fabric, copper tape, metal, wire, fruit, water, and any other conductive material. Each of Trill Craft's 30 channels of capacitive sensing offer variable readings, and multiple boards can be chained together to create interfaces with hundreds of channels of capacitive touch. Trill Craft comes with an unsoldered right angle pin header for the I2C pins so you can connect the board to Bela or your system of choice.http://shop.bela.io/trillBecky Stewart is a Lecturer in the Dyson School of Design Engineering at Imperial College London. She works with e-textiles and signal processing to build interactive, body-centric wearable computing systems.
