linux music tutorial: seq24, part 2

lsd — Fri, 05 Nov 2010 08:02:39 +0000

In the first part of my seq24 tutorial series, I looked at creating patterns in the pattern editor, and then triggering those patterns in real-time from the QWERTY keyboard. In part 2, I go in to more detail on both features. This video covers:

Advanced pattern triggering techniques: queuing and snapshots
Basic note editing: copying/pasting notes and changing velocities
MIDI CC automation
Background patterns
MIDI note entry (step-sequencing) and MIDI recording

It’s a little longer than I’d have liked, but there’s a lot in there! If you’d prefer smaller, shorter tutorials in future, feel free to leave a comment and let me know.

For downloaders, there’s also a 720p WebM version available (107MB).

linux music tutorial: seq24, part 1

I promised I’d make an introductory tutorial to seq24, and now, I’ve delivered! If you’ve tried seq24 in the past and been confused by it, hopefully this will clear up some of the mysteries; if you’ve never tried it, this might just encourage you to give it a go!

There’s an unspoken “step zero” here — get yourself a working copy of seq24. I’m not sure about other distributions, but on Ubuntu, especially 64-bit, the packaged version seems very unstable. The best thing to do is to grab the 0.9.1 version from the seq24 Launchpad and install that — this new release includes a bunch of bug-fixes, and a few new features, too.

The original plan was for a straight screencast, like my earlier synth tutorials, but I was so impressed by Kdenlive that I decided to have a bit of fun with it — hopefully the fun I had comes through in the finished product.

a demo of live sequencing with seq24

Despite a whole bunch of idiosyncrasies, I love seq24, and even though I tend to think of Qtractor as my MIDI sequencer of choice under Linux, it’s actually seq24 that I’ve used the most in producing my tracks. I’m planning on making some video tutorials for it, since it’s such a strange beast to deal with at first, but before doing that, I want to demonstrate the kind of things you can do with it.

Here, then, is a “performance” of my track tiny droplets — the various MIDI loops used are all pre-sequenced, but I’m triggering them all in realtime using my QWERTY keyboard. In this case, seq24 is driving Hydrogen and my Blofeld, and I’m using Ardour as a live mixer to process and mix the audio from those synths in to a stereo stream.

UPDATE: If you’d prefer to download the video rather than streaming it on YouTube, I’ve uploaded a WebM version of it. WebM is still quite new, but current versions of VLC and MPlayer support it.

On a brief side note, I have to give a shout-out to my good friend AutoStatic for describing his new video capture process using Xephyr and FFmpeg — I used it here, and the results look great. The audio was captured with JACK TimeMachine, and in another first for me, I edited it all together using the brilliant Kdenlive.

new track: phase transition

It’s been about six weeks since I posted my little SooperLooper jam, and here it is in its final form, or at least what became of it. This was a difficult one to pull together — I initially just polished my sketch version of it, but that didn’t give me the results I was after, so I ended up ditching that effort and re-arranging it from scratch, finally getting an inspiration for the central progression and ending last week. Once I had that idea, it didn’t take long on the weekend to flesh it out.

This is another Seq24/Hydrogen/Ardour recording, with Blofeld synths, though I also created my own drum sounds (mostly on the Blofeld again) for this one. I also used PHASEX as the synth for the lead arpeggio — it’s a simple patch, but I really liked how it sounded, so it stayed in the final version.

EDIT: Turns out that the download links were broken! I’ve fixed them now, so if you had trouble downloading, please try again now.

new track: tiny droplets

Two tracks in as many months? Madness! This is another ambient track, but without the drone — it has more of an early Aphex Twin vibe, but with some glitchy drums. I sequenced this in seq24, a pattern-based sequencer designed for live use, and in fact this was originally a “live” take, which I’ve edited and added to. Apart from that, it’s the usual suspects — Blofeld on the synth sounds and some drums, Hydrogen on the rest of the drums, recorded/mixed in Ardour.
