SKnote Necklace springreverb
02 jun 2011

Necklace is a spring reverb built by means of physical modeling,
that is writing mathematical models of the real thing.
It is rather efficient on CPU.

"Necklace" comes from the spring reverb with very long springs invented to emulate
the sound of halls and chatedrals.

It is stero and includes 6 springs.

The springs can be arranged in several ways to obtain different behaviour of
the "reflections".

The model is rather unconstrained, you can obtain realistic results or more experimental ones.

It is non linear, in that it can be pushed hard by input knob (you can compensate
for the extra gain with Volume knob) and change its envelope and response.

Parameters:

- Gain: input gain from -oo to +6dB
- Width: stereo width, from mono to original stereo
- Low: a hipass filter on input, before the springs
- Damping: a dampener for the springs. The higher, the shorter the sound
- Predelay: a clean transparent delay from the input to the springs
- Length: the length of each spring. All six springs have similar (but different) length
- Sound: controls fundamental parameters of the model. Cannot be defined.
Try and listen to the full reverb tail.
- Tune: controls the material of the springs, "centering" the response on different
frequency bands (from dark to brigth and thin)
- Vel: the frequency of modulation, from stopped to 2Hz
- Mod: the amount of modulation.
- Mix: the mix between dry signal and reverb. Set it to full wet when using the effect
in a send slot.
- Volume: the gain for the reverb, after the springs, from -oo to +6dB. It is PRE
dry/wet control!
- Structure menu (the large one): select the arrangement of the springs. They are described in a simple way:
3L 3R: three springs parallel on the Left channel, three springs parallel on the R.
2L 2C 2R: two springs parallel left, two parallel center, two parallel right
2->1L 2->1R: two springs parallel connected to a third spring, the same for right
and so on...

Tap on the springs to hear the impulse response while programming the reverb.
Don't expect a useless "tapped springs special effect".
It is the actual impulse response and is very useful when you start mastering well the effect.
