Early Schroeder reverberators consisted of the following elements:

- A series connection of several all-pass filters.
- A parallel bank of feedback comb filters.
- A mixing matrix.

The all-pass filters provide colourless high-density echoes in the late impulse response of the reverberator. These all-pass filters may also be referred to as diffusers. While all-pass filters are colourless in theory, perceptually, their impulse responses are only colourless when they are extremely short (less than 10 ms or so). Longer all-pass impulse responses sound similar to feedback comb-filters. For steady-state tones, however, such as sinusoids, the all-pass property gives the same gain at every frequency, unlike comb filters.

The parallel comb-filter bank is intended to give a psychoacoustically appropriate fluctuation in the reverberator frequency response. A feedback comb filter can simulate a pair of parallel walls, so one could choose the delay-line length in each comb filter to be the number of samples it takes for a plane wave to propagate from one wall to the opposite wall and back.

Thus, one may choose the comb-filter delay-line lengths more or less arbitrarily, and then use enough of them in parallel (with mutually prime delay-line lengths) to achieve a perceptually adequate fluctuation density in the frequency-response magnitude. In four such delays are chosen between 30 and 45 ms, and the corresponding feedback coefficients are set to give the desired overall decay time.

SyS TG1 is a multitimbral synthesizer with 2 individual voices and a waveform sequencer.

When we announced SyS TG1 in 2010 and sent out some Beta versions, we were so surprised by the massive amount of interest and the pure impact of downloaded demos, we almost had to shut the website down, because we weren't prepared for that kind of attention.
SyS TG1 must have hit a nerve, and here is why:
Coming from the C64 and 8-bit sound world, Wertstahl always wanted to have a Synthesizer, that acted like a SID Soundchip but in a 16-bit context. So he just took ideas from how the programmers on the C64 were generating certain effects to enrichen the sound of the very limited chip, like seqentially switching waveforms or using arpeggio-lists to create pseudo-chords. And like that, the heart of the SyS TG1 was born: the wave-morph-sequencer. Not only can you sequentially switch from one waveform to another while your sound is played, but the waves will smoothly morph. This generates a multitude of transitions of over- and subtones, giving the SyS TG1 it's unique sound.

Additionally, manipulation of sounds should be as simple and intuitive as possible, so we added a double LFO-Unit and an Akai S-1000 inspired 12-bit low-pass Filter. We didn't get it to make it's very distinctive erroneous high squeak sound when at 99% cutoff, but it is very non-resonant and softening. Just like we wanted it.

Also, deep inside the device, you will find some mixing-routine switch, and the Kraftwerk-Inspired "Stoerstrahlung"-button.
