Grove Audio USB Host Extender Module Prototype


via Grove Audio

"The USB Host Extender Module, GMS-632X is undergoing testing including the USB host capability and running Arduino sketches. The USB library is accessible from within an Arduino sketch and uses interrupts so the device detect, attach and eject functions continue to operate in the background while user code executes in the foreground.

Here [left] the extender module is mounted next to the GMS-632 USB/MIDI/CV Interface module. The two are connected by a short ribbon cable with IDC10 connectors. The extender module does not require a power connector. The extender module can be used with either the GMS-632 or the GMS-634 modules.

Here [below] the module is being used to host an m-Audio Keystation 49. Through the GMS-632 module, keypresses are converted into pairs of CV and gate signals. The GMS-632 is simultaneously connected to a laptop computer as a USB device, through which it can receive USB MIDI or program uploads.
