How precisely does Acid handle durations? SoFo? -ACID Product Family

Subject:How precisely does Acid handle durations? SoFo? Posted by: dkistner Date:11/18/2002 6:34:49 AM Before I do a lot of work in my scoring program, I'm curious if anyone knows how Acid handles durations in midi files. Like, if I alter note durations in my scoring program to be longer or shorter than 100%, will Acid respect these changes and give me what I want? Or will it force it all to 100%? I'm trying a fermata technique in Harmony Assistant (a GREAT program!) to effect a pulse (some call this groove quantize, although I'm not so sure it's the same thing). I know Acid ignores tempo changes. If it respects durational changes in midi files, however, I'm set!
Subject:RE: How precisely does Acid handle durations? SoFo? Reply by: pwppch Date:11/18/2002 12:44:00 PM ACID reads the midi file. The duration of a note is define by it start and stop times. (Stop - Start == Duration). These time stamps are relative to tempo, that is they are in a unitless number of ticks. One tick at 120 BPM has a different duration than one tick at 200 BPM. Standard MID files don't work with a percentage - there is no way for the MID file to communicate this type of change directly/generically. It all depends on how the scoring program will render to a standard MID file. Peter

Reply by: dkistner Date:11/18/2002 1:09:12 PM Sorry I specified in percentages, but another program I used to use taught me to think that way. I don't know anything about ticks, but I think that's what my scoring program uses to write durations. I guess I should just do some experimenting. Thanks for answering my question, Peter.
