Mothman 2000 is the commercial version of Justin Robert's Mothman 1000.

Mothman 2000 combines 3 forms of synthesis to create a unique sounding and easy-to-use software synthesizer. There are two main oscillators, the first is a standard waveform generator that has sine, saw, ramp, triangle, pulse, white noise, and pink noise. The other is a phase distortion oscillator, a technology pioneered by Casio in the 1980s for their unique CZ series of synthesizers that contains two separate waveform generators that each produce saw, square, pulse, double sine, saw-pulse and three resonant waveforms. There are VCFs on each oscillator and VCF1 features a dedicated ADSR section.

The LFOs are actually LFO/HFOs, low and high frequency. The first is connected to the Amp section of OSC1 and the second to the pitch of OSC2. At low oscillation settings they can be use for traditional LFO FX, yet at HFO settings they function as FM operators that can totally change the sound. Using this combination of FM synthesis over top of PD and Analog-style subtractive synthesis makes for some truly unique yet still musical and usable sounds.

Justin says that the logical and intuitive design make it very simple to program even if you don't know a lot about synthesis. There are also ASDR envelope generator sections for each oscillators output that can allow you to create everything from huge warm pads to more staccato brass and piano sounds.

Upgrades from Mothman 1000 include a stereo digital delay, velocity sensitivity, slick brushed metal skin, improved performance, 64 patch memory slots with 32 added user memory slots, as well as new presets.
