Guns
Always popular so we try to keep a few in stock. Made with excitor-resonator systems, convolving and distortion techniques.
Automatic gunfire audio mp3
Footsteps
Another favorite with everyone so a few types here. Made by modelling the foot pressure on the ground and then changing the ground texture procedure.

"Electric Monks"
These guys are FOF (my own el-cheapo pof (phase aligned formant units)) singing voices. They are connected to an low frequency excitor that gets more energetic, so the monks meditate and get more enlightened. When they reach the transcendental enlightenment threshold they stop and ring the bell. Just a crazy synthesis example really, but disturbingly funny.
"Randi Ghandi"
Delay based models of strings give cheap but good results. Getting this kind of synthesis to work is all about carefully choosing a handful of parameters, delay times and feedback levels. This instrument is 3 series resonators and application of a little chaotic lfo to the delay times of the 2nd and 3rd stage. That controls the secondary and tertiary harmonics, but not the first so it remains pitched about a controllable point. Feeback filters are chosen to give a hard, bright steel string sound.
"Resobass"
Delay based resonant modelling keeping a circular buffer from saturating while filling it with signal fragments. A way to manage the growth or decay of signals is careful "jailing" using clipping or compression units. This lively little oscilator takes the peak dynamics of a drumbeat to produce a sound that follows it until it changes again. Subtle differences in the tone of the input signal have large effects on the timbre of the signal which the resonant part finally settles on.
"Really Sacry"
Granular synthesis, all about splitting up sounds like voices into their individual "atoms" and recombining them in a new order can make some crazy new sounds. Drama and action film producers love this technique for atmospheres.
"Tireless Drummer"
Delay can be used on a larger scale for constructing complex rythmns as well as for making complex waveforms on the smaller scale. A single bit randomly toggles from one to zero to make a step impulse. That feeds an arrangement of 4 series delays each with feedback into the n-1 and n-2 stages. This simple cicuit can produce endless intricate snare drum patterns. The one here does some other whacky stuff to show off its potential, like changing delay times on the fly.
The Adventures of "Motorbike Bob"
"Motorbike Bob jumps over the moon" - Motorbike Bob, good old Bob..
"Mouthy modular"
A reed model accidentally found for an FM method. Increasing the spectral width and playing chords gave an unexpectedly good harmonica noise. It's a hard to get a good harmonica or mouth organ sound and this curiously does a great job of tracking the formants aver a wide key range. What seems to work is that a comb effect makes alternate chords in tonic scales sound like one breathes in and one breathes out.
