OK, I'm feeling a little brain-dead about this at the moment, but I'm confused about formatting the Bytes field in the MIDIOutputEventInBytes prototype. The default example is "144 60 127" which results in a Channel 1 Note On C3 vel 127. OK, the note number and velocity are apparent, but how the 2 nibbles of byte 1 are expressed, channel number and message type, is where I'm stuck. What would this message look like if it were, for example, channel 16 Note Off? Or a CC on channel 11? IP: Logged |

You can enter the values in hexadecimal if you prefer: 0xC0 0x3C 0x7F IP: Logged |

"0xC0 0x3C 0x7F" Ah, that's interesting. I had been entering hex based on the recommendation in the Help. So, Note On - Ch 1 - C3 - vel=127, expressed as: 16r90 16r3C 16r7F which is the same as: 0x90 0x3c 0x7f which is the same as the decimal format: 144 60 127 So, my brainfart mistake was converting the hex for the channel and message type separately, which is silly Any reason the Help recommends the 16r prefix rather than 0x?

and just results in 90 anyway.All times are CT (US) | next newest topic | next oldest topic |
