Adder was designed to be a PC VSTi additive wavetable synthesizer. Adder uses additive, wavetable/shaping, subtractive & FM synthesis to create an enormous range of sounds.

Here are some key features of "Adder":

· Adder uses 32 partials, each partial can use one of four different waveforms. Sine/saw/triangle and square waves are initially built in but you can use any small sample as a waveform (300 waveforms are supplied with Adder for your use).
· Partials - each partial has its own volume, harmonic, tuning , FM & phase settings, and each belongs to one of eight volume and pitch group. These groups are use in the modulation matrix so partials can have different volume, pitch & FM envelopes / LFOs etc
· Samples - Adders built in sample loader allows to load in any short 16 bit sample. Samples can be looping or single shot and can be retriggered using step sequences. A sample shaper allows filtering, reversing, distortion etc .. of any of the samples.
· Filters - two 12/24 low/high/band pass/band reject + ring mod or comb filters. Each partial can be sent to either or both of these filters. These filters have built-in distortion and waveshaping and can be use in serial or in parallel
· Fat Mode - in this the first sixteen partials are doubled and detuned so to create fatter sounds. Combined with stereo widening this creates much bigger sounds
· Playing Modes - Adder can work in poly , mono or legato mode.
· Modulators - Adder has eight envelopes, step sequences , XY pad and LFOs. Envelope can have up-to 32 stage, each stage having variable slopes. Each envelope has user-definable loop & release points for complex patterns.
· Modulation matrix - a powerful modulation matrix allows you to modulate all the controls using envelopes , LFOs , step sequences, any midi controls ,velocity, note played and in/out volume.
· Effects - Cross delay, chorus/flanger, 3 band equalizer and compressor effects
