PCB ONLY USB MIDI INTERFACE 3X3 WITH ROUTING/MERGE/SPLIT -OP À RENNES

USBMidiKliK3x3 / 3 MIDI IN X 3 MIDI OUT   - The KikGenLabs WARNING: THIS AUCTION IS FOR A PCB ONLY. NO COMPONENTS MOUNTED. This PCB is a prototype and is considered as "new" and is fully working. You must buy components yourself. An easy job. No surface components at all. See schematic at the Github project page:  https://github.com/TheKikGen/USBMidiKliK4x4 The USB MidiKlik 4x4 firmware allows the following features : - The board is USB Powered, so no additional power supply necessary. It works driverless as a class compliant device, with Windows XP SP3, Vista 32 and 64 Bit, Windows 7 / 8 / 10   32 and 64 Bit, and Mac OS X, Linux ALSA, Akai MPC Live/X/Force, IOS, Android.  - USB Powered, no additional power necessary - 4 USB IN / OUT - 3 MIDI IN / 3 MIDI OUT JACKS - Configuration with SYSEX and/or user menu from a terminal connected to the USB serial port - Support of very big SYSEX files transmission - Hardware reset remotely by Sysex  - Sysex to switch to configuration menu serial mode - Ability to change the USB device ProductStringName of the device, and also change the USB Vendor and Product Ids.  Changes persist after power off.  - STANDALONE Mode:  can be used as a standalone MIDI routing box without connecting any host - Stackable:  several interfaces can be used, to get 6x6, 9x9 MIDI ports,  without any conflicts as Name, VID & PID can be changed. - Complex routing rules configurables by sysex or from a user menu - Routing rules allow you to transform the USB MIDIKLIK into a MIDI MERGE or a MIDI THRU very easily. - Ability to route any USB IN to any USB OUT/ MIDI OUT (7 targets possible 4 USB, 3 Midi jack per board) - Midi messages filtering: channel voice, system common, realtime, sysex   The firmware is open source so you can adapt or modify it for you own needs. The project is active.
