This is addressed to Mark, but if anyone else has any ideas, please let me know. Thanks

Hi Mark,

Being a computer-savvy man, I thought you might have a simple answer to my problem or some ideas, anyway.

Here's what I'm trying to accomplish and have run into some problems:

Setting a minimum off time between like notes so that the Pianocorder solenoids have enuf time to retract between repeating notes.

I have Powertracks, the default resolution appears to be 292 ticks per quarter note. The program has an "eliminate note overlap" function, which only goes up to 15 ticks, which will, in a couple of clicks, search out all like notes and make a minimum off time between them of 15 ticks. Well, sort-of.

I use the maximum 15 tick setting as regards the following:

Initially the "eliminate note overlap" function would set a minimum spacing between any two like notes whether they actually did overlap or not. As long as there were less than 15 ticks between the two notes, the option would work, by reducing the duration of the first note.

Ok, so far. However I soon found that what I really needed for optimum performance was a minimum off time of 25 ticks.

Just discovered that I can reset the resolution from 292 to 120. 25 ticks at 292 is about equal to 15 ticks at 120. So, I thought I had it made!

However, fate had other ideas in store.

When I attempted to utilize the overlap function set at 15 ticks with a resolution of 120, I found it to be totally abitrary about finding and adjusting the notes. It would do a small percentage, but cannot be relied upon to do the job correctly.

Of course, it is offerred as an "overlap" fix not a "minimum spacing" fix, I apparently was just getting that as a bonus.

If the notes actually do overlap in time, it seems to do the job and also subtract the 15 ticks. If they do not actually overlap, but are just closer than 15 ticks, some may adjust, most do not. Go figure.

Ok, so I reset the resolution back to 192, figuring that I could at least get some consistency on spacing the off times at 15 ticks there. Now it will not work well in that format either, unless there is an actual overlap from which to work.

Are you familiar with other midi editing programs that would have a function that you could set to search out and adjust the minimum off times between like notes?

And/or any other ideas how I could approach this problem?!?

Thanks for your help,
