Well, it's nearly 2am but my latest creation is still buzzing round in my head and simply won't let go :( The is a development of my entry to the current KVR contest. The percussion intro (which, with variations pretty much runs on through the whole tune) is from the toy instruments we are supposed to use. I used the following soundfont samples: Magical Music Box Cathedral Toy Organ Cimealong Just as the tune proper starts I use the kick drum from the P51f soundfont, this is timed to coincide with what sounds like someone hitting a saucepan - that's because it's exactly what it is :o In the middle quiet passages I introduce more P51f - I'm quite pleased with the way this turned out. I usually struggle with percussion. The synth sounds are all ZynAddSubFX - bet that surprised you :) The background pad is 'Smooth' First phrase is 'Beyond' + 'Soft Voyager' Next comes 'Overdrive', then 'Steel Wire' The rich, rolling bass is from 'Ethereal' The very last sound to come in, on the last phrase is 'Super Square' Qsynth channels carrying all the percussion were passed through an instance of jamin, and Zyn. was passed through a separate instance. The two were then simply passed on to timemachine to record in one sweep. Rosegarden was the sequencer. Due to the truly random nature of the sound of 'Overdrive' it actually took me 7-8 tries to get exactly the right effect over the whole piece. The very last step was to pass the recorded whole through Audacity where I shaved 2dB off the spikes with the fast lookahead limiter, restored to 0db, then trimed the start and end. So here is the final result: http://www.musically.me.uk/music/No_More_Time_For_Toys.ogg P.S. Please ensure you have a good bass response to get the best from that 'Ethereal'. Quite high volume wouldn't go amiss either :) -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

Re: [LAU] [PlanetCCRMA] linuxsampler, qsampler

by Jonathan E. Brickman

I have been using JSampler Fantasia on F13 for a number of months now, with complete success. I use the LinuxSampler web-site package for JSampler Fantasia, controlling the F13 standard 'linuxsampler' package.

[LAU] DIY MIDI controller

by Igor Brkic

Hi to all! I just wanted to share my latest project with everyone. It's a DIY MIDI (foot)controller based on arduino and that runs on Linux. Hardware part consist of a arduino and a few keys and knobs. But software part is more interesting. It creates new alsa MIDI device and allows you to bind any number of MIDI messages to any control. So, for example, I can bind few keyboard chords to keys on a footboard and play it as a background while playing guitar. If anyone wants to know more: http://hyperglitch.com/articles/ctrlr Cheers!

[LAU] OT: Live SuperCollider drone performance

by micromoog

Hi all, Here's a live SuperCollider ambient/drone performance I did last night at the gallery/performance space Open Lot, in Nashville, Tennessee, USA. It's about half an hour, and was a live collaboration with two artists -- an abstract oil painter and a video artist. I used pure SuperCollider running on Ubuntu. http://lawrencecrow.bandcamp.com/track/open-lot-2010-09-16 micromoog (Lawrence Crow)

[LAU] re Subconscious Affecting Music

by david

I asked a friend of mine, who's rather intellectual about music, about the book someone mentioned in this thread, of ancient Greek thought on the effect of music on the mind: > I have heard of it, and read about it, but that isn't the work one > would cite if you were looking for a scientific study of the effects > of music on the subconscious mind. > > I am not familiar with the literature, but I am aware that there has > been a lot of nonsense written on the subject. -- David gnome(a)hawaii.rr.com authenticity, honesty, community

[LAU] jack-dssi-host and client names

by Julien Claassen

Hello everyone1 Is there a chance to tell jack-dsi-host, which client name to use. I find a name like: hexter DX7 emulation (v0.6.2):hexter DX7 emulation (v0.6.2) out_1 rather cumbersome. But I didn't see no options with my jack-dssi-host for naming.

[LAU] Other Places

by Folderol

I wonder how many people here submit music to either non-Linux sites, or at least ones that are poorly represented. I maintain and artists page with occasional entries on :- http://www.muzic.com These people are linked with the Internet Archive. Unfortunately they insist on mp3 files, but nevertheless it's a place to strut your stuff, as they say. I don't always mention that my tracks are composed on Linux systems - don't want to scare people off :) Another site I contribute to is :- http://www.kara-moon.com/forum/ Anyone is free to browse the forum, but you need to register to submit anything. This is a *very* friendly group. You get a lot of support and suggestions, and there is nearly always a couple of multi-person collaborations in progress. There are about 3-4 of us that use Linux, and it's just no big deal. Sometimes we get asked questions by the curious - in which case we answer of course without trying to evangelise! Finally, I also make postings on :- http://www.kvraudio.com/forum/viewforum.php?f=14 This is the KVR music cafe. It is a popular site and has a *very* fast music turnover of just about every style imaginable. Sadly I think I'm the only Linux player on there :( I particularly enjoy the monthly themed contest. It forces you out of complacency as you never know what the theme will be. This month is easy actually. The tune can be what you like but must include at least one child's toy instrument (samples are accepted). Also, this month you have to write at least 10 reviews of other artists work :) -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.
