Tangible Waves

Notes: The FILTERBANK914 is designed after the famous Moog 914 Fixed Filterbank. It includes 12 bandpass filters with fixed center frequencies and additionally a lowpass- and a highpass filter. Control knobs for all the frequency bands allow individual mixing of the bands. This is especially useful for shaping the sound spectrum similar to acoustic instruments - they get their character by certain frequency peaks, so called "formants".

This module is different to (and not a good choice as) a multiband equalizer. The equalizer can increase/decrease certain bands in the range of e.g. -12...+12dB, with the signal unchanged with all controls in center position. In contrast, the FILTERBANK914 controls are attenuators over the full level, meaning the individual band is completely muted when the knob is turned completely counter-clockwise.

As a special feature, the module has separate outputs for "even" and "odd" bands, meaning that one output only contains the sum of half the bandpasses, the other one the remaining ones. This leads to some type of "pseudo stereo".

Notes: The TBD module is a multifunctional DSP (digital signal processing) module that includes more than 30 different synthesis and audio processing plugins. It is a collaboration project between CTAG Kiel (an academic working group of Kiel University of Applied Sciences), instrumentsofthings.com (who produce this module for Eurorack) and tangiblewaves.

The module looks quite simplistic with it's only three knobs and three buttons, but the power lies in the web based user interface for editing and storing the parameters. For editing, the module is connected via USB to your computer and a small software tool running here is the bridge to the editing of the parameters via your web browser. IMPORTANT TO KNOW: When the editing is done, the module runs autonomously, without a computer!

Up to 10 favourites can be stored on the module and be chosen by the CONFIG button.

Dynamic control of the modules' parameters works via the two CV inputs and two trigger inputs (which are linked to two buttons), and two knobs are also available for live tweaking parameters. The assignment of inputs/knobs to actual parameters is done in the web based user interface.

Please note that the TBD module has mono audio input and output (compared to the Eurorack version which is stereo); plugins that do stereo audio work also in the AE TBD, but only on one channel. ("Why only mono?" you might ask; the limitation to mono is due to licensing agreements to keep the module price in the usual AE range.
