The HV Intruments are exclusive acoustic creations from sound designer Harm Visser that show the true potential of Tassman.
The experimental musician has a new tool at hand: a two-bowed-winding-plate instrument for extensive metal ringing madness.
The Violin Pizz is a simple patch. The secret is in the excitation sample for loading in the Player module: it's a short knock on a violin body. So the String module is fed with some frequencies of a real violin.
Stringed FM uses four one-mode string modules as modulators for the carrier oscillator plus feedback—with remarkable results. You can create lots of weird and spooky timbres: from pure electronic to almost acoustic sounds.
The mouth harp is a simple instrument found in many cultures as Jew's Harp, GewGaw, Jeu and many others.
Invented by August Mustel in 1886, the Celesta looks like an upright piano, but has metal bars instead of strings. It has a high pitched and gentle sound with a rather short decay. It resembles the sound of a Glockenspiel...
The word FOF is an abbreviation of Fonction d'Onde Formantique (Formant Wave Function). It is in fact a special case of amplitude modulation, where a stream of short grains (pulse train) excite a damped sinewave. This process causes a formant region. The FOF method can be used to create the human voice, but also for musical instruments. This patch uses a VCO (pulse) that feeds a string with only 4 modes, so nearly a damped sine wave, with a very short decay. The result is a violin/cello timbre and some others. But as the demo let you hear, you can also use the grains as a separate musical or effect element.
Tibetan Bells II features a sound that is hard to describe. We could say that the sound has a 'moving', irregular decay.
One of the most interesting aspect of the Tenor Sax patch is the non-linear behaviour of the bowed resonator. It's extremely sensitive on how hard you press a key. It can cause effects as growling, multphonics and overblowing.
