SPI control Signals from the microcontroller are used to produce the primary sound using VCOs. It then passes through filters and modulation elements controlled by buttons and potentiometers that the user can work with. This project involves equal parts of Digital Signal Processing and Analog Electronics. MIDI signals use UART protocol for data transfer.

The features of a keyboard that we are planning our device to provide for are:

  • Monophony
  • Low Frequency Oscillator (LFO)
  • Frequency Modulation (FM Synthesis)
  • Amplitude modulation
  • ADSR Control
  • Wah-Wah Effect (Analog)
  • On Board Preamp for headphone output

Features of the LPC2148 MCU used are:

  • UART
  • Timers
  • VIC
  • GPIO
  • ADC/DAC
