I do use seq24 in live for several years, together with many things,

including Tapeutape, which is a sampler.

seq24 is using ALSA for the midi, so the latency depends on the

capabilities of your machine.

However, I never had any problem with it concerning latency, knowing

that I use very short latencies, as my system also manages monitors for

musicians.

One thing, though, when playing, the tempo can't be changed in seq24, so

you'll probably need to set it as a jack timebase slave and change the

tempo on the master. My timebase master is sooperlooper. Still, I

experience a little sync problem: when starting playing the sequences,

the beginning of the very first events in the sequence (the ones being

at time 0 of this sequence) often aren't played (they're played all

times after). I'm not sure everyone has this problem, as I'm using a

"really-crappy" patched by my hand version of it.

If you're talking about external midi control, it's quite easy, but the

.seq24rc file is quite unreadable!

You mean : changing the page of your patterns, to switch to another 8x4

sequences matrix? or you're talking about queue?

Anyhow, both of them are possible.

For the first question, you just have to change the screenset (in the

official version, you only can switch to next or previous screen with

MIDI control, the version I patched allow you to select the screen you

want directly through a MIDI control). Then, you'll have to set 'play

this screenset' or something like that (can't remember exactly) to say

that you now play this screenset (the shortcut is "End" in my version,

should be the same for you).

If queued is concerned, then you might tell seq24 which MIDI control

will enable queue mode, then when selecting a bunch of sequences, next

time they reach the end, the new 'mute-group' will be selected (and

played).

OK, that question is answered just above.
