    INTRODUCTION: EZ MIDI Control is a flexible and accessible way to add MIDI, savable presets and tap tempo to nearly any effect design. Integrate this time saving solution into your effects designs with MCP42xxx digital pots and/or control voltages. Available as a 36 pin through hole solder board or as LQFP-48 ICs.
  • Page 4 EZ MIDI CONTROL PINS: PINS DESCRIP TION Some input pins can be damaged if the input voltage exceeds 3.3 volts. Some pins are 5 volt tolerant. ANALOG SIGNAL INPUT: Biased to 1.65 volts. Used for envelope LFO/modulators. Pot inputs. 0 – 3.3 volt input.

  • Page 18 STARTUP PARAMETERS: Applicable when EZ MIDI Control is built into an effect with EEPROM1 configuration. On startup EZ MIDI control reads the EEPROM to retrieve customization design data, user presets and power up data. The power up data consists of two parameters, the MIDI channel and MIDI clock enabled/disabled.
