| The GM5 is a USB MIDI interface IC from Ploytec. It provides up to 5 independent MIDI inputs and 5 independent MIDI outputs. It is only available in a surface mount package, and only in large (250+) quantities. TK organizes regular bulk orders for this IC. | The GM5 is a USB MIDI interface IC from Ploytec.

| It requires no additional modules to offer basic MIDI I/O functionality. | The MBHP "USB GM5 Module" is a simple PCB which holds the GM5 IC, and all required components for one MIDI input and output. It does not require any other MBHP modules to provide basic USB<>MIDI I/O functionality. A single MIDI input and MIDI output jack may be mounted to the board, or connected via SIL headers. An additional 4 inputs and outputs may be connected to the module via a single header, in which case each physical i/o would require its own support parts (optocouplers, resistors, diodes etc). "Digital I/O" pins are also available for direct interface to a Core module, with no need for optocouplers. |

| The MBHP "USB GM5 Module" is a simple PCB which holds the GM5 IC, and all required support components for one MIDI input and output. To keep the board size small, a single MIDI input and MIDI output jack may be mounted to the board. An additional 4 inputs and outputs may be connected to the module via a single header.

"Digital I/O" pins are also available for direct interface to a Core module, without need for optocouplers. | ==== Alternatives ==== |
| |
| Alternatively, the "GM5x5x5" module has been designed, which fits the GM5 IC and all jacks and parts for a full 5 MIDI inputs and outputs. | An alternative to this module is the "GM5x5x5", a standalone 5x5 USB MIDI interface on a single PCB. |
| | |
| | Another alternative is the USB PIC module, in which USB is wired directly to a PIC-based Core running special (non-MIOS) firmware. Further development of this module is unlikely, given the low cost and great performance of the GM5. |

| | |
| | No drivers need to be installed to use the GM5 with Linux or Mac OS X computers. It is a class-compliant device. |
| | |
| | Windows computers may work with the GM5 using the Microsoft's driver, however the Ploytec driver works better. |
