M-theory is capable of a rather wide range of sounds, and it excels at creating hybrid sounds that have some characteristics of acoustic instruments.

M-theory is a hybrid synth that is built around the Karplus-Strong physical modeling technique, and uses samples, VA oscillators, and noise to drive the delay based oscillator, resulting in a very wide range of high quality synthetic and synth/acoustic hybrid modeled sounds.

• Karplus-Strong style synthesis engine.
• Dual exciters, each with the option of samples, VA, or noise sources.
• Option to load your own samples.
• Oscillator damping, pluck/bow, and tone modes.
• Independent low, band, high, and all-pass filters.
• 6 LFOs.
• 4 envelopes.
• Dual programmable arpeggiators and an extra MIDI note trigger/doubler feature.
• Built in effects: tremolo, metallic resonances, chorus, delay, and reverb.
• 320 presets.
