Creating Your Own Custom Rayblaster Filter Impulse Responses; Filter Types - Tone2 Rayblaster Reference Manual

7. Creating your own custom Rayblaster filter impulse response
1) Open any synth
2) Play a low pitch sawtooth (around 50 Hz) with any filter (cutoff around 1kHz, you
can add some resonance if you want)
3) Record and save this static sound to a wav.
4) Cut edit this wav into a single-cycle waveform.
5) Load it into one of Rayblaster's oscillator.
When you edit the sample it is important to have a zero-crossing at the beginning and end
of the wave. You can also adjust this in Rayblaster with Osc. Start Offset, but it is more
easy if you do it in the source file before importing it into Rayblaster.
Lowpass type is with formant lower than 0 and bandpass type with values above 0. There
are some example Impulse responses included in the Wave library (OSC>Load Wave
menu) like the LpSaurusReso. As window function use OFF, Soft Saw or Exponential.
An example patch can be found in the Tutorial category > FakeAnalogFilter.

Filter types

The advantage of importing filter impulse responses is that it allows you to create both
existing filter types as well as as new types of filters. Below is a list of some example
filter types and how to set them up.
32 dB FIR low-pass
1. Init all
2. Harmonic: -9
3. Start Offset: 30
4. Window mode: Sinc
72 (!) dB resonant FIR low-pass
1. Init all
2. Harmonic: -9
3. Start Offset: 30
4. Window mode: Sync BP3
Low-pass Comb Filter
1. Init All
2. Harmonic: -9
3. Start Offset: 30
4. Window mode: Comb 2x
