Over on the Camel Audio forum is a thread about making LFO's and Oscillators for "Alchemy".
Reads like this:
A set of appropriately pre-configured "presets" e.g. "Alch-OSC-1" through "Alch-OSC-19" which could be loaded sequentially into your plugs via SoundForge/WaveLab (et al) and the result applied (obviously) would be a very welcome thing for a whole lot of aspiring oscillator makers.Oscillator Format
The oscillator file format contains 20 cycles of a waveform, each lowpass filtered with a progressively lower cutoff frequency. This is to allow the oscillator to be used over a wide range of frequencies without significant aliasing.
The cutoff starts at one half-octave below the nyquist frequency and then goes down in half-octave decrements i.e. the frequency is divided by sqrt(2) each time.
Start with a raw waveform of 2048 samples, apply the necessary filtering to a copy and then appending the filtered result to the initial waveform.
Repeat this 19 times total, while progressively increasing the amount of filter applied. Save the result in RAW format, then load in to Alchemy.
