Each Operator has: Ratio / Fixed OSC Frequency settings. A 4 level envelope generator and keyboard scaler. AM and PM. Velocity Sensitivity. Operators may be disabled with an on/off switch. An output level. The oscillators may be arranged in 8 different algorithms similar to the ones found on the Yamaha TX81z. A 4 stage pitch EG is useful for messing up the pitch signal before it enters the operators. A delayed LFO. ... [more]

Tramp Model A is an FM Synth with 3 Operators that can be configured into 4 different algorithms. Features: Each Oscillator has Sine, Ramp, Saw, Triangle & Square Wave. Frequency is set by keyboard pitch with ratio adjustments up to +- 5 octaves. A control also can be used to tune up or down 1 octave in semi-tones (notes). Each Operator has a separate 4 stage envelope generator; the rate settings can be multiplied for attack and decay rates that can run into minutes. Each Operator has a separate control for setting the sensitivity for Velocity, Amplitude Modulation or Pitch Modulation. An... [more]
