PTM-1 Parallel To MIDI Conversion

Allowing simple electrical input states to be converted in real time to MIDI standard note on and off messages, this MIDI-to-Parallel converter can be used in applications such as:

• Converting piano/organ keyboards, pedalboards and stop tabs to MIDI controller devices
• Scanning of cardboard book or paper roll music to produce MIDI files
• Real-time control of MIDI devices in live theatre and music shows
• Adding MIDI sound generators to mechanical instruments
• Novel musical instruments such as the ‘laser harp’
• MIDI sequence playback control
• And much more…

The PTM-1 has the following features:

• Supplied as a single high quality glass fibre pcb with gold-plated finish, measuring 185 mm x 95 mm
• Five 3.2mm mounting holes provided on the circuit board
• 128 logic-level inputs, user selectable between active low (pull-down) and active high (pull-up)
• Industry standard 20-way IDC input connectors for use with ribbon cables
• 5-pin DIN socket for MIDI out
• MIDI output channel selected by on-board switches
• Logic-level inputs for MIDI Start, Stop and Timing Clock real-time synchronisation signals
• Integrated ‘de-bounce’ logic for note, Start and Stop inputs
• Minimal latency (320 microseconds) on the Timing Clock input for high timing accuracy
• Powered by a DC supply anywhere in the range 8 to 35 volts via high quality rising-clamp screw terminals
• Indicator LED shows green when power on and changes to red when any note inputs are active
