I've sent some Ideas to follow regarding Portamento settings but it seems that it was not posted.

PORTAMENTO CC 65
PORTAMENTO TIME CC 5
PORTAMENTO CONTROL CC 84
The portamento function smoothly changes the pitch from the last key pressed to the key currently being pressed. When portamento is received, the portamento effect is turned on or off. The speed of the pitch change is set with the portamento time. When portamento control is received, the SOURCE NOTE NUMBER (key pressed last) is specified. Hope this will enlighten any member who are surfing this site.

I keep meaning to have a go at programming the steel guitar in Matthews Southern Comfort record Woodstock
Hey, I'd like to hear that! You happen to have it in at least 128/44.1 MP3 format? (192 preferably)
JohnG said:
hope he's on the road to recovery now?
Yes, finally! Now I have to sit on him to keep him from overdoing it!
I said:
BTW, is there an actual graph on the MMA site I can look at while I'm re-reading all of your writings on the subject?
JohnG said:
No, unfortunately not, it's in the GM2 spec. Look in your PMs in a day or so.
Thanks, I got it.... now I need to understand how to read it. Yet, another of my lackings in my basic edge-a-ma-kay-shun. LOL!
JohnG said:
Just wondered if you ever figured out how to get portamento working?
Hidden away in one of my earlier posts was a bit that said something about setting the channel to "mode 4", "mono mode on". The GM2 spec certainly implies that this is a requirement for the effect. I've more info if you need it.
Is that turned on in that cool demo file you sent me? Don't think I'd know what to look for, but I bet I'd find it on my copy of Table 3. What other info are you talking about? I can never learn too much! LOL
John G said:
Since your question I'd spent a little time looking up the subject and it seems to have changed, in the setup procedures at least, from GM to GM2.
Oh yeah? What are the differences? Most often I have to stick pretty much to GM when I sequence for the gang here on MIDIMart, due to not having a clue what their equipment will and won't handle.

Ramon,
Thanks for the nitty-gritty CCs and individual CC explanation. Great for a quick reference.

Hey, I'd like to hear that! You happen to have it in at least 128/44.1 MP3 format? (192 preferably) Er, no! In wav format on a CD. But I'll see what I can do. Good news! Be gentle JazzCat, be gentle. Okay, you asked for it. Here goes! Graph courtesy of the MMA.  Okay, looking along the bottom edge of the graph you've got a set of numbers, there should be a "127" at the very RHS of the graph, but it's missing. Those numbers (0 - 112 plus 127) represent the cc#05 setting. Running up the LHS is another set of numbers representing "cents" per millisecond speed . (Cents meaning hundredths of a semitone, millisecond being a thousandth of a second.) These represent how quickly the note slides from the last note to the note you've just pressed. But for most of us I imagine the scale is difficult to work out. So let me try and make it more meaningful. What might be useful is if the graph told us the slide rate in how many semitones per second, yes? Actually it's not that difficult to do just a bit of division and multiplication. Run across the numbers along the bottom of the graph until you come to 32. Stop there and look up the line until you come to the line of the graph. Now run to the left to see how many cents/msec that is, I get 10, very roughly. So 10 cents per millisecond. I want to convert to seconds so I need to multiply by 1,000. Then I want to convert to semitones so I need to divide by 100. So 10 x 1,000 / 100 = 100 semitones per second. So if we set cc05 to 30 the rate of change will be 100 semitones per second (roughly). Very quick. Now look across the bottom of the graph to the number 80. Go up and find the intersection, 1.00 cent/msec. Now instead of doing all that multiplication and division just multiply by 10. 1 x 10 = 10. So if we set cc05 to 80 the rate of change will be 10 semitones per second (roughly). Much slower. cc05 = 100 would probably be about 5 semitones per second. Now I wonder if that's any clearer? I'm sure you'll let me know. JohnG. |

Is Cat having a little poke at me or am i misunderstanding what she has said above  ? i don`t sequence but i do understand the language which in the first part of the post was quite technical to anyone that doesn`t sequence.If i have misunderstood then i apologise but if not then i shan`t post on technical queries again weegeo |

No, I dont think she was having a go at all wee George. Just thanking Ramon for his quick summary and questioning some of my over techy input. (I know I can overdo it sometimes but thats how my brain works and what I was paid to do back when I was an employed person.) Sadly I cant get out of the habit. It's all so simple I just cant understand how people find it so difficult. Now if I was to try and describe the ISDN D channel protocol with its 48 bits in 250 microseconds with B1 and B2 channel Bytes interspersed with D channel bits and framing, DC balancing, D echo-channel, auxiliary, activation and multiframing bits and its NT to TE and TE to NT offset then I could understand that people might have difficulties. I did for quite a while. And my students always did? It's a complex protocol.  But MIDI is just easy peasy. I think I'd better bung a few smilies in here in case I get taken too seriously. ;D  JohnG. P.S. Think I might move some of this over to my MIDI section if nobody has any objections. |

weegeo,
I have no idea what was said where, that you could have in the remotest way conjured an idea that I was poking at you. The only person I've been poking at is myself... for my less than par mathematical skills and my less than par understanding of John's tech explanations.
Believe me, if I take a poke at someone they will have no doubts about it, as I'm a no holds barred sort when it comes to that. Just ask around! LOL!

Yes, please John, take all the pertinent portamento schtuff over to your section, sans the yickity yack about hubby's surgery, my 'edge-a-ma-kay-shun' and pokes. LOL!
Oh, and please take Ramon's post there too, if he doesn't mind!
