Re: [LAU] Usage of undefinded MIDI mesages

Nick, it is a Dr. Boehm CnT/L. These organs were sold as a kit until about 1982. This one was made in 1978. I have stripped out all of the old analogue circuitry while keeping the drawbars, push buttons and turning knobs, and using the circuit boards of a MIDIbox64 project I built my own MIDI controller. The two manuals and pedal were already converted to digital via a genuine Boehm MIDI controller, but the drawbars, pushbuttons etc. were not. I have finished the hardware part of the controller, now I am busy getting the programming to work. There are several things that make the whole business rather complicated: I am planning to mimic the behaviour of the old single finger chord drum accompaniment and recreate the rhythm section. And I want to switch between GM compatible SF2 sounds and B4II organ. All of these have their own features that have to be made to work with the drawbars and switches. And there is an LED panel as well, that should display the function of the buttons and drawbars when operated or give other useful hints. I have finished programming the MIDI box64 controller part although at the moment it does not much apart from sending a SYSTEM EXCLUSIVE message when pulling drawbars / pressing switches, and I want to use keykit for tracking these messages and converting them into MIDI messages for the applications that I use. I think that using an external "host" application for preparing all of the MIDI stuff is easier to use because it offers more memory and is quicker to program. There is more to come as soon as I have things working together as expected (more "convenience functions"). I have used the SYS EX command now with an "arbitrary" ID that I hope no other component (hardware, software) is recognizing apart from keykit - but only because I will tell keykit to recognize it... It seems to me that NRP controller will produce too much overhead for simply switching a sound on and off. I know that normally a PRESET CHANGE would do that, but such a command cannot toggle sounds, like stops of a church organ, but only switch between them. Regards, Crypto.
