fluke Posted February 17, 2006 Report Share Posted February 17, 2006 I want to build a MidiBox FM and use a PalmPilot (specifically my TRGpro (http://handera.com/Products/TRGpro.aspx)) as the control surface. I also want to be able to plug a keyboard in to control the MidiBox FM and have the PalmPilot recieve the data from the keyboard as well for use as a sequencer. To top it off, i'd like to include my Yamaha DB50XG (a WaveBlaster card addon to the SoundBlaster 16) in there as well.I know i'll need 2 MidiMerger units, how i separate the data going to the MidiBox FM and the Yamaha DB50XG? Both would be listening on all 16 midi channels wouldn't they? Do i need to build some sort of reverse MidiMerger that buffers the midi messages and sends channels 1-10 to the Yamaha DB50XG only and 11-16 to the MidiBox FM? Or are there some standard SysEx commands to tell a device to ignore certain channels?Sorry if this is an obvious question, i'm just starting out with midi devices.

stryd_one Posted February 17, 2006 Report Share Posted February 17, 2006 How about:Keyboard ----> Palm ----> MBFM ----> DB50XG ?Or is that too simple? ;) Quote Link to comment Share on other sites More sharing options...
fluke Posted February 23, 2006 Author Report Share Posted February 23, 2006 I couldn't do that because i need a bi-directional connection between the PalmPilot and the MidiBox FM.I think i've figured out a simple way to do it. If it split the output of MidiMerger 1 into two AND gates, i can use two output pins on the PIC to turn the signal on and off to each device based on which channel the message is going to. Which means i just have to add one 74HC00 chip to the circuit. Quote Link to comment Share on other sites More sharing options...
