hi, still new at BX-24...I am trying to send out MIDI data, using the information I found here. Unfortunately, instead of sending out what I intend to send out I send out a lot of nonsensical data on various MIDI channels (program changes, now and then a 'note on', after touch, etc...but mostly system resets). I tried 2 circuits, one with the 2n2222

I'm trying to make a drum trigger to MIDI converter with a BX-35. In order to communicate at MIDI's baud rate of 31,250 I was thinking about either using the normal 7.3728Mhz crystal on the BX-35 and using a MAX3100 with a 4Mhz crystal or something close to communicate. But I've read that using SPI can cause a lot of problems. Would it be easier to simplify thing

I have a working BasicX-24 system which takes keyboard on/off messages and creates MIDI messages to an electronic keyboard. This has worked fine for over a year. I am creating a 2nd system to convert MIDI messages on the fly for a friend who has a non-MIDI Standard system. On booting the BasicX-24 I successfully generate a bunch of test note on then note off messages. Code below: ...

I have an operating Pipe Organ Combination Action controller using a BX-24 to scan 88 pistons and control 512 stop magnets. This works very well. My customer would like to have this same device monitor a MIDI data stream and, using a unique channel (5), simulate the pushing of one of the 88 pistons. In the MIDI mode, the BX-24 does NOT have to be scan


Suggestions for MIDI wireless data transmission

I need to transmit MIDI data @ ~32000 baud from a BasicX-24 over a distance of ~20 feet (could be line of sight if needed). I would prefer...

I need to transmit MIDI data @ ~32000 baud from a BasicX-24 over a distance of ~20 feet (could be line of sight if needed). I would prefer not to have to modulate/demodulate a carrier unless it can be done very inexpensivly. The X-24 is already running fine at close to the proper MIDI baud rate so I was thinking of IR but I am willing to entertain other ideas. I would appreciate any lo

Hey, I'm making a synth with a bx-35 and am using a MAX3110 as the MIDI uart. And am using this schematic: http://devices.sapp.org/m icro/stamp2sx/max3110/bsmax3110big.gif as a reference (but with the Basic Stamp replaced by the BX35). I've got all the SPI communications working fine, and MIDI

I have a BX-24 running a pipe organ scanning routine and one of its modes is to output data in MIDI format which requires a baud rate of 31,250 and setting Register.UBRR = 14 works perfect. However, I would like to communicate with the BX-24 over the hardware Comm1 from my laptop. My laptop does not support the MIDI baud rate and I event tried a VB/Wi

Hi again, No, this isn't about John Tesh's music. Looking at the formula on Tom Igoe's excellent webpage, it occurs to me that a 7.5 mhz crystal would give you EXACTLY 31250 for a baud rate. Are such crystals available, does anyone have a source? Surely this is
