[seq24-users] sound problem with jack transport

[Demetra K. <de...@gm...>]

Hi,

I am running Seq24 with Jack, Hydrogen and ZynAddSubFX, all properly 
linked in Jackctl according to the guidelines found here:

https://help.ubuntu.com/community/HowToSeq24Introduction

Everything works fine, and I can hear the ZynAddSubFX instruments and 
Hydrogen drumkit in the pianoroll editor, but playback produces no sound 
(after having created a song pattern of course, having configured the 
output bus settings and having enabled the midi playback).

Here is the output I get from Hydrogen when I hit play:

[WARNING]   Hydrogen            [audioEngine_process] trylock != 0. 
Frames = 66560. Lock in Hydrogen::addRealtimeNote

I have only just started using Seq24, and haven't been using Jack for a 
very long time either, so if this sounds familiar, or if I'm making an 
obvious error, could you please point me to the right direction?

Many thanks,
Demetra

[seq24-users] MIDI Start/Stop

[Bjorn W. <bj...@gm...>]

Greetings all,

I've been messing around with Seq24 and JACK-based linux audio
experimentation for about a year and a half now. Seq24 is a simply
brilliant bit of software, thanks to all involved.

The feature I'd kill for would be MIDI triggering of start/stop. In
the same vein, being able to trigger start repeatedly, so every time
it's triggered, the loops jump back to the beginning (pressing play
while Seq24 is already playing does nothing now...). This would be
extremely useful for syncing manually when DJing (sooperlooper has
this feature, and it's the only thing that keeps me using it).

[seq24-users] My lonely request and offer to contribute

[Dubphil <du...@fr...>]

Hello,

step by step seq24 has become the center piece of my musical performence 
system, along with ecasound.
Almost perfect, it would be  great if opening a new midi file  on the 
file would change the suitable tempo.
And I suspect that opening a midi file on the fly is really buggy, it 
survives, but the time take to seq24 to completely load the midi file 
gives stranges sounds ;). (loading a midi file "on the fly" means while 
seq24 plays back)

I would like to help for this project as high as I can (perhaps the 
french translation ?)

Best regards

Philippe

Doesn't for me, unfortunately :-(

[seq24-users] two minor feature requests; patches attached

[adolson <ad...@gm...>]

Hi Rob,

I was hoping you would accept the two patches I have attached to this email.

--

seq24-label-fix.diff

This one-liner simply shows the MIDI bus number on the main window on
a scale of 1-16 instead of 0-15. This is more in line with the MIDI
channel number display, as well as in the menus for the MIDI bus,
where they are numbered 1-16. I have been using seq24 a lot in the
past few weeks, and this gets a bit confusing sometimes. If I check
via the box label what bus a pattern is playing on, when it says 10,
the actual bus is 11, and so it throws me off because 10 is the one I
want (since this is where I have connected Hydrogen via JACK). It's
just a consistency fix, to help get rid of some confusion.

--

seq24-menu-changes.diff

As I said, I have been using seq24 a lot in the past few weeks, and
it's been bugging me that to quickly change the MIDI channel that a
pattern is playing on I have to either right-click and Edit and then
change from the menu there, or right-click and go to Midi Bus > [same
Midi Bus I already have selected, which is numbered differently than
what is labeled on the box, hence the above patch] > new Channel
Number. I frequently forget and change the bus by mistake. So what I
did with this patch was broke the thing into two menus, MIDI Bus and
MIDI Channel. Now you can change either/or very quickly and easily.
The only thing better than this patch (that I could think of) would be
to point the cursor at a pattern box, hold CTRL and mousewheel to
change the bus, or hold ALT and mousewheel to change the channel (but
this is beyond my programming skills at this time..).

--

I Ccd the user list in case anyone else finds these patches useful.
They apply against the latest 0.8.7 release and compile cleanly (they
are very minor changes, really).

Thanks for the consideration, Rob. And I'm sorry that my first patches
weren't something more spectacular that you have been requested for
more often. :)

Right-click once in empty space and then press delete. It works for
me. It is still a bug, yes.

As many keyboard shortcuts as possible would be great, I agree. A good
way to do it might be a config file or at least for menu items, allow
them to follow the GNOME menu config, so you can change them
on-the-fly.

I am using 0.8.6 on Ubuntu, and I go into the song editor, left-click
to set the left side of the selection I want to play (staring point)
and then the right side with right-click. Then click the looping
button so it is depressed/enabled. Now when I hit play, the song
starts playing at the left marker, wherever I put it. Works for me.

[seq24-users] new release + issues + wishes

[<att...@gm...>]

Hi

A while back we talked about a bug involving user names and 
--manual-alsa-ports flag. Has that been fixed, and if so could I get 
this from cvs/svn somewhere?

A number of issues + wishes:

1) If I select all notes with "select->all notes" and press delete the 
selected notes (all notes) will not be deleted (unlike if I select them 
by drag-select). I guess this is a bug...

2) I think the following keyboard shortcuts would be really nice:

C-a: select all notes
C-q: quantize selected (or all if none selected)
space: start/stop playback

Others nice keyboard shortcuts would include. "select none", "invert 
selection", "strength quantize" "set quantize note value", and "set grid 
snap value" (could be using some combination involving 1-9) and "delete 
selected pattern (on song editor) (delete key comes to mind).

3) How is the round robbin feature coming along? I see this (and other 
useful stuff) implemented here: 
http://www.desfonema.com.ar/index.php?page=software. Is that something 
that is being merged into the main source?

4) When running seq24 alone (no ardour) I really, really miss the 
ability to start playback from a certain point in the song editor. A way 
to start playback from loop start (key shortcut could be "C-space" or 
"return") would be ideal, when you're working on a certain section of a 
track.

Looking forward to hearing what you all think...

[seq24-users] midi-sync problems

[<lin...@ya...>]

hello erverybody,

here is my problem:
midi-clock works fine, but mmc does not work perfect. sometimes it does,
sometimes, it starts, but not in sync (but clock signal is still coming).
tested with korg electribe sx and yamaha motif6. do not have these
problems with muse, so alsa-sequencer should work fine...

anybody else, who has this problem? any ideas that could help?

thanks and greetings

[seq24-users] some feature ideas (not requests)

[Jordan A. <jor...@gm...>]

hi fellow seq24 users.  Here are a few functions that would be really cool.

1)  Dragging and dropping track position in the pattern and song
editors.  This would make it easy to put similar patterns near each
other when you're sorting a messy pile o' patterns.

2) Multiple pattern selection.  This would allow you to instantly
assign multiple patterns to the same midi bus.  If I could do that, I
might just open up a separate seq24 instance for each intrument!

cheers,
capsid

Re: [seq24-users] Notes too early when recording to Ardour sync'ed with jackd

[Rob B. <rc...@fi...>]

Are we sure its seq24 shooting off midi early and not the click being
delayed?

If you have seq24 send out some midi to a drummachine or something and
record that back in ardour, how are the waves lining up when zoomed way
in ?

seq24 triggering early would look like this:

ardour timeline:     |0   |1   |2   |3   |4   |5
recorded wav beats:  |=3D- X=3D-  X=3D-  X=3D-  X=3D-  X=3D-

it should look like this:

ardour timeline:     |0   |1   |2   |3   |4   |5
recorded wav beats:  |X=3D-  X=3D-  X=3D-  X=3D-  X=3D-  X=3D-

[seq24-users] Notes too early when recording to Ardour sync'ed with jackd

[Niels O. <ni...@dr...>]

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hello there,

yesterday I did my first real recording with Ardour and seq24.

I need to set jackd to a buffer of 1024 samples in order to avoid xruns.
However, when I do not run seq24, I can go down to 256 samples without
getting xruns.

But that's not the issue. The issue is: Notes from seq24 are too early.

(I have an external sampler connected to an M-Audio Midi Sport Uno
interface.)

seq24 is sync'ed with jackd and Ardour is the time master. All notes
come in before the click. This is especially annoying when I want to
record some audio to the not yet recorded drum track (which I have in
seq24).

After recording I can manually move the track, but that's not as
intended. I can't plan the entire drum track ahead without knowing how
the piece will go.

Is there a way to delay the output of seq24? Furthermore, is there a way
to have this adjusted automatically?

I'm using realtime-lsm, Kernel 2.6.17.11 on Gentoo, Ardour 0.9.33, jackd
0.100.7, seq24 0.8.7 and an RME Hammerfall Digi 9636 soundcard.

Any hints are welcome, the recording isn't finished yet! ;-))

Best,

   Niels

Ok, I've got that already.

My problem is (hopefully better explanation than my last one follows):

1) I want to start playback at a say bar 90, how do I do that?

2) Seq24 is stopped. I want to start it directly in the loop (which is 
set to say bar 90-93), how do I do that?

On song editor you got a [L] and [R] markups on top. with right button 
you set the right side of the loop, with the left button you set the 
left side of the loop. with the looping button [L <=> R]  you enable 
looping.
that should be .

It seems that seq24 with looping on doesn't start at the loop. Also I

here you can add new events (of type: you selected it just before) just
like you do for adding new notes, then you can change their value in the
velocity pane
