MORE DRAWBARS FOR ALL! If you feel the need of physical drawbars, the D9U is what you need. The D9U is the Crumar's first open-source Arduino-based project sold as a Do-It-Yourself kit or pre-assembled. It can be completely reprogrammed or hacked by an experienced Arduino maker, or used as is for controlling either the lower or the upper drawbars. Has built-in Class Compliant USB-MIDI from which also draws power (no need of an extra PSU!) and also offers a traditional UART MIDI port by means of a TRS mini-jack connection on the side. Can be used with many other clonewheel organs or synthesizers from other manufacturers, is perfect with organ plugins such as GSi VB3-II.
