Certainly it must be possible to generate a midi file with a time signature in it. The midi file created by my patch should open 3/8 instead of the standard 4/4. Is there ways to do such from within max? Or do I have to wait until 22nd...

creating-a-midi-file

The seq object in max does not record midi meta events including time

signatures and key signatures. Maybe in Max 5? Multi-track sequences too?

The seq object in max does not record midi meta events including time
signatures and key signatures.  Maybe in Max 5?  Multi-track sequences too?

... replying to myself (for the record), changing or adding meta events is possible with javascript. A good start is the example for file i/o and the midi file-format description to be found eg here:

Which part is not the case.  i haven't checked recently but when I  
did try, seq ignored mete events.
I wrote my own program in APL to accept text based midi data and  
create a multitrack midi file
(using the spec below) that includes time signatures, titles, etc.  I  
am currently testing MaxScore
for this so I can go directly to a MusicXML file that Finale  
understands.

This works for exporting to Finale and Sibelius.  What I am missing  
is an object that will read and
play type 1 midi files made perhaps with finale, sibelius or other  
programs that write midi files.

This spec is well known to me.  I have been handling midi files in  
Pascal and C since the spec came out.

I'd also like to know of a way to record changing time signature MIDI meta events while recording sequences within Max using seq, detonate, or another approach that can write a standard MIDI sequence file once the data is recorded.

Does anyone know if this capability is available now in an object in Max 5?

Any pointers to more information or help is greatly appreciated.

I'd also like to know of a way to record changing time signature MIDI meta events while recording sequences within Max using seq, detonate, or another approach that can write a standard MIDI sequence file once the data is recorded.  

I have come across an object by John MacCallum at CNMAT called "mxj midifile" that enables playing and recording midi meta events along with other midi data. This is done using the "addMetaEvent" time-stamped message which is followed by the data needed for each type of meta message (see MIDI spec for meta event numbers and necessary data). Mxj midifile reads and writes type 0 (and type 1, I think) standard midi files much like seq and detonate.

John MacCallum's object can be found at the CNMAT download site:
