Analogue Inputs to MIDI Out

This allows up to 8 analogue inputs (with a range from 0 to 5 volts) to produce selectable MIDI control output commands. The analogue inputs could be rotary or slider potentiometers which are connected to 0 to 5 volts. Also the inputs could be connected to Force Sense Resistors (FSR), Light Dependent Resistors, Magnetic hall effect sensors via suit

able interfacing etc. Note that unused inputs should be grounded to the 0 Volt line to prevent spurious noise pickup. At power-on, if the Menu switch is simultaneously held ON, then the unit will enter programme mode. Then each push of the menu switch moves through the menu. The menu consists of the following: Programming the Analogue to MIDI Unit only has to be done once and the range values are stored internally in the EEPROM and the unit will continue to operate in this mode, even when power is removed, until reprogrammed. In Normal mode the 8 analogue inputs are scanned and the corresponding MIDI controller data is transmitted on a particular MIDI channel. The MIDI channel has a range from 1 to 16 and the controllers range from 0 to 121 as shown in table 1.
