Driving around

The time has come around again for the release of another Six String Bliss album called Driven To Bliss. This is the tenth collaborative album produced by this community and the fifth on which I have participated. There should be a download of the actual album soon.

My contribution was a version of Open Car by Porcupine Tree, one of my favourite bands. I wanted to try something a bit heavier than usual, but this also has some acoustic segments. There's a mix of time signatures in there. I based my recording around a MIDI file I found so that could cover the drums and keyboards that I would not have time to sequence. I wanted to concentrate on the guitars and vocals.

Recording was in my usual set-up based around KXStudio on Ubuntu Studio. The DAW was Ardour 3. This is still awaiting final release, but proved to be pretty stable. The main advantage for me over V2 is the inclusion of MIDI so that I didn't need to run a separate application for that. I ran the output to QSynth/Fluidsynth using a free soundfont from the Ubuntu repositories (more on that later). Having everything in one application makes life easier when you want to mute specific tracks and I was doing that a lot with the MIDI tracks I was using to guide what I played.

Guitars were my Gordon Smith GS2 via my Roland Cube 80x (R-Fier model), Dean Performer E electro-acoustic (recorded acoustically) and Peavey bass (direct). Vocals and acoustic guitar were via my Zoom H4 recorder with line out to my M-Audio Delta interface.

I did consider using software amp models in Guitarix, but didn't have time to experiment enough with that. The Cube did a fairly good job, but I could possibly have got a bit closer to the original tone. It took me a while to get the main riff down, but then I had to play the same on bass! This was a challenge.

I like doing double-tracked vocals. I tried singing some in a different register, but not totally happy with the results. Need to work more on my harmonies.

I also intended to do more playing around with things like EQ and compression to improve the general mix, but that didn't happen due to the deadline and some other things going on. I may still try those on the track to see if I can improve it and learn more about these tools.

The album was produced and mastered by long-term Blissner JMan. He noticed something strange about the waveform of my track that caused some issues with the mastering.

I had noticed it looked odd, but had been preoccupied with just getting it sent off. I noticed that the acoustic sections were offset from the zero line. This was narrowed down to one of the keyboard sounds. To fix it I quickly found another soundfont. I could possibly have used a different patch on the existing one, but I've not quite figured out how to do this.

So, here it is. This is the pre-mastering version. All comments and (constructive) criticism welcome. I'm still in the early days of learning about this recording thing and anything that adds to my knowledge is welcome.

KXStudio

I've been aware of KXStudio for some time. The main (only?) developer, falktx, hangs out on the Linux Musicians forum and is always quick to respond to queries. He's put together the latest audio applications in a form than can be installed on top of various Linux distributions, including Arch and Ubuntu. He's also developed various applications that help to tie it all together and make life easier.

I actually installed KXStudio some time ago when it was released as a stand-alone distribution based on Ubuntu. I played with this for a while, but it didn't seem quite ready back then. I was hearing about lots of new developments recently and wanted to give it another try.

One route was to install Ubuntu Studio first I tried this multiple times, but eventually realised that my old PC just cannot boot from a USB drive of over 2GB, and the ISO was just over that. So I used the 'Net-Boot ISO' method that starts with a tiny image and installs the rest over the internet. That worked fine. I'm installing it as a secondary boot on my only PC as I need to keep the existing system working for use by the rest of the family. This is a slight inconvenience as I have to re-boot to do recording, which takes away some of the spontaneity.

I'm using the XFCE version as a change from my usual KDE and also hope this will improve performance. I'm also using the default theme, which is a little dark for my tastes. I may change that as I find it hard to see some window controls.

One difference from most distributions is that KXStudio generally runs JACK all the time and routes normal system audio through it. Cadence is used rather than QjackCtl to configure JACK, but the options are similar. I still have to find optimal settings, but I was getting low latency and just the occasional xrun.

The main application I've played with so far is Guitarix. This emulates various types of guitar amplifiers and effects. The options are a bit bewildering. There are lots of valve/tube types to select from. I can't say how close it gets to real amplifiers, but it sounds very good to me. There's some good effects too. I particularly like the reverb. I can see me using this a lot for future projects. There's Rakarrak too, but Guitarix looks like it might be better to get a basic guitar tone.

I've also had a play with Ardour version 3. This has lots of new features to explore. The input/output connection matrix is neat and I like the overall view of the track that helps to see where you are. I have a project that needs some MIDI, so I need to check out that aspect.

Anyway, here's the first this I recorded on KXStudio, using Guitarix. I'll report more when I've had more chance to play.



Update: Good write-up of how some of this stuff works from the Linux Musicians forum.

Blissful Floating

I've been a member of the Six String Bliss community for a few years since I discovered the podcast. It's small compared to some other guitar sites, but very friendly. I've met several of them and regularly chat with others. One of the fun features is the production of an album twice a year. A topic is chosen and people can submit songs either individually or in collaboration with others. I've been on a few of these now. One was a collaboration with several others on a Slade song, but the others have been solo efforts. Previously I have not done full song recordings with multiple parts, so these have been good opportunities to learn about the process.

Previously I've used a MIDI file I downloaded for the backing, but this time I wanted to do it all myself. The topic was 'Songs released in 1987' and I chose She Drifted Away by Hüsker Dü from the Warehouse: Songs and Stories album. It seemed fairly simple and achievable. Then I found myself thrown by the 3/4 time signature. I wrote a bit about how I worked around this previously. Once I had the drums I did the main guitar part with my Roland Cube 80x running direct and recorded in Ardour. I managed to accidentally slightly change the feel of the intro riff, but I don't worry about exactly copying the original. I think I did the first vocal take next, but slipped up slightly. I was monitoring on headphones, but didn't realise I'd left the PC speakers on! You can hear it on the track, but I didn't think it worth re-doing just then. Then I added bass. I'm no bass player, but I've got a Peavey Milestone bass from a friend which I ran that through my Zoom H4 to use one of the bass amplifier models. I need to experiment more with those as I wasn't hearing much difference between them.

I added a couple more vocal tracks to give a bigger sound on the choruses. It wasn't intended, but the result has a bit of a sea shanty feel to it. I also doubled the main guitar part and added some high parts where the intro riff is repeated using a different model with more gain on the Cube.

I asked my friend JMan to have a listen and offer his opinion on what effects I should add to make the mix work. He had a few hints about use of reverb and compression. The bass in particular needed something to make it more consistent. The compressor settings I ended up with gave it a grittier feel that I liked.

Trying to mix was not helped by having blocked ears at the time. That's what prevented me re-doing vocals and the deadline was looming, so I sent it off as it was.

The album was launched in a special show. It's fun to hear the details of each song and the opinions of the hosts Clint and Alicia. Alicia has said before that she's a fan of my singing (!) and was disappointed that I did an instrumental last time. I think she actually said that this track was her favourite on the album. Comparisons were made to They Might Be Giants and Steve Howe, which I'll take as compliments. As always I am stunned by the quality of tracks that others put out. Mine sounds distinctly amateur by comparison, but I'm really happy to be accepted as part of this community. I'm looking forward to the next project.


You can download the album for free. Reviews are posted on the forum.

Bluesing

I had a bit of time alone at home, so took the opportunity to turn up the guitar amplifier for a change. Generally I play acoustically to keep the family happy.I bought this blues course a while back and keep returning to it to learn a bit more. It's been a bit of a challenge, but has pushed my playing in some new directions. I did a quick recording using my Zoom H4. The audio is not great as the amp wasn't even pointing the right way and the backing track was playing through the PC speakers. I messed up a few licks and then just did my own thing for a bit.
