This was one of my first attempts to implement an simple and not so DSP heavy Reverb algorithm. According to Manfred Schroeder, you could create Reverb by sending a signal through a series of Allpass and/or Comb Filters, which is the basic concept of SCHROEDER.
The signal is sent through 4 delay lines simultaneously, each with a feedback loop. The delay times are all set a bit apart. After that follows a series of 2 allpass filters. This goes for each channel (L/R). With "TIME" you can alter the delay time, with "INTENSITY" the amount of feedback. Both can be used to lengthen the reverberation effect. Additionally there is a simple "HP" and "LP" filter to shape the tone of the reverb tail.
Disclaimer: This implementation is not exactly as Schroeder has presented it.

Shiny knobs are included as always, jKnobman however felt like adding pixel errors into them... for whatever reason.

- SCHROEDER implemented and GUI created
- comes with 14 awesomelicious presets, from cheap room/hall recreations to crazy comb and glistening effects

Thank you very much Eduard Telik bro...!! very nice echo/reverb effects.
