Date: 13 Nov 1996 From: Nenad Stojadinovic To: pics@parallaxinc.com Subject: [PICS] MIDI Does anyone know of a good bit of software to receive MIDI on the 16c84? I have been trying to make my version work with a 4MHz xtal and so far no go. On the other hand I'm currently writing the firmware for another MIDI device for the 16c74 and as far as I can tell, BRGH=0, SPBRG=7 at 16MHz for 0% error. That's what I call service. Thanks folks Date: 16 Nov 1996 From: Nenad Stojadinovic To: pics@parallaxinc.com Subject: [PICS] MIDI programming To the people that were asking about MIDI programming, my email address is : vladimir@u030.aone.net.au I am fairly new to this MIDI stuff but I am fortunate in having a few tame music experts to help me out. Currently I am working on a trigger for old synths and things which triggers on the MIDI synch signal as well as any note you care to teach it. It also divides by the standard 6,8,12 and 24 to output to synth clock inputs. This one works but the muso's want some extras. I am also doing the code for an arpeggiator on a 16c74. Date: 14 Nov 1996 From: Nenad Stojadinovic To: pics@parallaxinc.com Subject: [PICS] MIDI stuff OK, OK it was a false alarm, my MIDI reception firmware seems to work just fine. I found out that when breadboarding, it is really important that the red wire goes to MCLEAR. Anyone wants a copy just ask. Question to the Parallax wallas: Why can I not write to the data EEPROM in the 16c84 with the Parallax software? No matter what I tried the write cycle hung up. I finally did it by writing the setup info in Microchip language ie, MOVLW 55h MOVWF EECON2 MOVLW 0AAh MOVWF EECON2 BSF EECON1,WR etc The manual does say that timing is critical but I thought the Parallax lingo and Mchip was equivalent.

You can access it directly as: http://www.amc.com/chipdir/oth/midi.txt (If you want to take the scenic route, you can find it via the list of abbreviations.) You can probably also find a FAQ and other interesting stuff about MIDI, using a search engine like Alta Vista. Success!

You can access it directly as: > http://www.amc.com/chipdir/oth/midi.txt hi, my name is nathan and I read your file on midi.. sounds interesting.. did you get the drum triggers going? I am new to using microcontrollers and I was wondering if you could point me in the right direction. I want to make a simple midi -> trigger interface in order to bring some of my old drum machines up to the rest of my gear .. I was wondering if you knew of any simple ways to get this going or of any lists which I could send questions to without offending too much. basically all I need to do is take midi signals off one channel and output about ten voltage triggers that have a level determined by the velocity sent over midi. any help would be greatly appreciated. ____ nath Date: 14 Nov 1996 From: David Haile To: pics@parallaxinc.com.wgcinet Subject: [PICS] MIDI stuff >Nenad, Please post your email address.

Sorry, but I didn't participate in that thread... You can probably ask the persons in the thread, but try to quote liberally, so they recognize what your question is about... >I am new to using microcontrollers >and I was wondering if you could point me in the right direction.

I don't think that people here or on the 6811-list will mind to discuss it, but MIDI was traditionally probably more oriented towards Motorola chips. (MIDI interfaces in sound chips on PC sound cards still contain Motorola 6850 UART's for example), but I see no reason why PIC's couldn't handle MIDI. Groeten, Jaap Date: 18 Nov 1996 From: Ing.
