Introduction
The kibibu Doof 1.5 is a generator. To install it, stick it
in your \Gear\Generators folder under your Buzz installation
The kibibu Doof 1.5 was designed originally as a kick drum
generator. However, with the incorporation of various waveforms
and filters, it has become a somewhat more general purpose (yet
still slightly weird to operate) mono synth.
Basic operation of 1.5 is mostly the same as version 1.0, however if
you haven't messed with that, here is the run down on the parameters:
- WaveType
- Selects the waveform to use. Can be:
- Sine
- The firmest and punchiest. A pure sinusoid
- Saw
- The sloppiest and squishiest. A positive saw wave (ie. starts negative, goes positive, then snaps back to negative)
- Square
- Reasonably straightforward square wave (no PWM)
- Triangle
- Would be better called Faux Triangle. Same great harmonic flavour, with increased phase coherence! (ie. generated with sines, not cosines, so it sounds the same but "looks" different
- Noise
- White noise. Fuzzy and rich, like Oprah with a beard
- iNoise
- White noise, degraded. Scratchy and mean, like an angry DJ.
- StAmp
- The amplitude that the waveform starts at at the start of the note
- StFreq C
- A constant frequency in hz that is added to the sustain (note) frequency
and the track frequency
- StFreq Trk
- The ratio of the initial/start frequency to the sustain/note frequency
- StFreq Shp
- The shape of the curve via which the frequency shifts from the start frequency to the note frequency.
Between 0 and 1 will not cause any overshoot of the frequency (i.e. the frequency will stay between start and note)
- StAmp Shp
- Conceptually identical to StFreq Shp except dealing with amplitude
- StLength
- Start length. How long it takes to get from the start frequency to the note frequency
- SusLength
- Sustain length. How long to stay on the note frequency for
- SusAmp
- Sustain Amplitude. How loud the sustain section will be
- EndFreq C, EndFreq Trk, EndFreq Shp
- Similar to their Start section equivalents
- EndAmp Shp
- Similar to StAmp Shp, except that the final amplitude is ALWAYS zero
- EndLength
- How long before the note fades out to zero
- FiltFreq C
- A constant filter 'cutoff', in hz
- FiltFreq Trk
- A multiple of the current generator frequency at which the filter will sit
- FiltRes C
- Constant filter resonance
- FiltRes Trk
- How much the resonance follows the generator frequency
- FiltType
- The type of filter. These are all based on the State Variable Filter posted by Andrew Simper to MusicDSP.com
- LP
- Low pass
- HP
- High pass
- Notch
- Notch (i.e. frequency cancelling)
- Band
- Band pass
