The u-He Twangstrรถm is a flexible spring reverb box-of-tricks. If you’re familiar with Bazille, you might already have come across its built-in spring unit. u-He took that one, then modeled two more reverb tanks, paired it with drive section, filter stage, envelope, and mod matrix. It emulates a hand-picked selection of the most popular units you will find in classic guitar and instrument amplifiers, recreating the odd character of real springs.
As a faithful emulation of a mechanical device, Twangstroฬm needs to be handled well. Many of the technical parameters are user-adjustable in real time, and these can be controlled via MIDI or using the internal LFO and envelope generator. With its multimode resonant filter, Twangstroฬm is a unique and powerful tool which can deliver highly unusual, evolving textures… especially when the signal is tossed around using the modulation matrix!
Shakeable springs
Hitting your computer wonโt make Twangstrรถm shatter, so u-He added a twang control. This is used to shake the springs, either manually or through modulation and automation. You might think this is a gimmick for which you have no further use (apart from waking up the neighbors), but if you modulate it slightly, everything comes to life!
Tank controls
Twangstrรถm’s reverb is based on physical modeling. As opposed to plug-ins based on impulse responses (IR), u-He’s approach mimics the physics of mechanical reverberation. By simulating the wavefront traveling through a medium, all the aspects of excitation, reflection, dispersion, interference, and other audio properties can be included. Twangstrรถm does not mimic the sonic result, but simulates the physical device. This means that all dimensions of the device are controllable in realtime, on a per-sample-basis โ which all boils down to quite some power at your fingertips!
Envelope
The envelope in Twangstrรถm features 4 different modes and can pick up the signal from either input, output or external sidechain. You can select between Envelope Follower, Attack and Decay, Attack and Release, or Cyclic modes. The last one is similar to a 2-stage LFO. Shown controls will adapt to the selected mode, with Threshold not appearing while in Envelope Follower mode.
Modulation Matrix
The modulation matrix has three general purpose modulation slots, and yes, you can select shake as one of many targets to modulate the Twang control!
