Orangator
Orangator is a fantastic piece of software, and it's free! The hardware equivalent would cost a fortune. Among its many features are:
- 10 Oscillators with multiple waveforms including graphic (you draw the waveform), sample playback, and additive (you define the harmonic content). Sync, ringmod, FM, and phase mod.
- 4 Envelope generators including one graphic.
- 2 LFO's and noise generator/filter modulation source.
- Filters.
- Basic sequencer.
- Effects, including delay, chorus, reverb and overdrive.
- Many modulation options.
- Realtime capability, although I've not been able to get this feature working.
- Visual Orangator, its companion program. VO allows you to construct your own instruments from the basic building blocks (Oscillators, Envelopes, Filters, etc.).
- Only one "VCA", although each oscillator's volume (and for that matter pitch and wave shape) can be modulated by a variety of sources, effectively giving one "VCA" per oscillator.
The Demo MP3 of Orangator sounds plays the following presets, one after the other. They are all sampled at C3 in mono at 44.1 kHz, trimmed, normalised to -0.9 dB. A few of them are peak limited:
