  2. Selected Project The i1 • A musical instrument • New variation on synthesizer • Mounted like a keyboard or upright like a cello • Enables user to produce varied sounds • Digital Effects including echo, auto-wah, and distortion • Analog overdrive effects • Continuously variable frequency selector • Requires both hands to play

  3. The Instrument Analog Comparison System Frequency Selector Attack / Decay Control Summing Amp Low Freq Oscillator Signal Routing Digital Controls Analog Audio Analog Controls Analog Control DSP State Serial 16 bit Digital Digital Control Analog Audio Output Analog Effects DSP Processor Power Supply Pre Amp Joe Mike Kahnec Filter DAC Jason Bounnong

  4. Standard Requirements

  5. Performance Requirements

  6. Frequency Selector Continuously variable selection Frequency range of 1.5 octave per selector Distance between chromatic notes between 2 and 5 cm Multiple Tap Selectors Selectable effects processing Patch synthesized audio through effect or bypass Analog Potentiometers To control output amplitude To set amplitude attack To set amplitude decay Performance Requirements User Inputs

  7. Performance Requirements User Indicators & Displays • Displays • DSP effect state indicator – three digits • Level of effect applied • LED Indicators • System on/off state • Analog effect state

  8. Performance Requirements Modes of Operation Any Combination of Analog and Digital Effects • Digital Effects • On/off • Effect • Echo • Distortion • Auto-Wah • Effect intensity • Effect parameter • Analog Effect • On/off • Adjustable overdrive intensity
