[A little OT] MeeBlip -- open source synthesiser

by Q

Hello everyone Whilst looking at NAMM-related music news yesterday, I stumbled across something that I thought might be of interest to some people here -- I don't think it's been mentioned before, apologies if it has. http://meeblip.noisepages.com/ "What is it? "MeeBlip is a hackable, affordable digital synthesizer, made for accessible sound and hands-on control. It can be someone’s first synth. It can be a unique-sounding addition to your music setup, playable with MIDI hardware and software. It can be a synth you open up and modify, learning about sound creation, code, and electronics. Or it can be the basis of new projects and ideas. "* Out of the box, a monophonic virtual analog synth. * Eight user-definable knobs and sixteen slide switches, for hands-on control with the immediacy of a classic monosynth. * Tasty digital synth sounds." And the bit that I thought might be very tempting to some: "* Use it as-is, or use the source code to remap controls or completely redefine the instrument’s architecture." The no-soldering-required, push together kit is $129 and there's a kit which does require soldering for $79. Schematics are on the website and code on gitorious.org. I've got virtually all of my synthesis needs covered already (mostly analogue with a bit of VA), plus I'm no programmer and not into circuit-bending or electronics. I'm still kinda tempted though -- good job I'm broke! But I thought others here might find it interesting. Kind regards Q -- A musical collaborator: "Lethargy, hm really? Then it will be time for me to get over there and just accidental idea the $h!t out of you"

New recording

by Bob van der Poel

In case you're wondering how good MMA generated background tracks can sound ... I've just completed a recording of the Latin/Cuban song "Silencio". All recording was done here at "Mellowood Studio" and then professionally mixed by my friend Oren in Victoria BC. Wonderful how collaboration over the Internet works. Give a listen and enjoy: http://mellowood.ca/music/recordings/index.html#silencio Best, -- **** Listen to my CD at http://www.mellowood.ca/music/cedars **** Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bob(a)mellowood.ca WWW: http://www.mellowood.ca

yoshimi battles the Intel Atom N270

by cal

Poor yoshimi's been in quite a bit of bother over the last few weeks. Having recently defended the stability projections for 0.060.1, it was a bit embarrassing to learn that it might well eventually prove "stable", but it was producing 3 or 4 incorrectly pitched notes per octave on some, but not all 32 bit builds. 64 bit builds were fine. With some tweaking, ie reverting a couple of clever little "optimisations", we got it to the point where it was mostly fine, but not on eee netbook thingies with an Intel Atom N270 cpu. Now that was a merry little chase, still is. As things stand, I added to the signal handler, clearing all floating point exceptions on receipt of SIGFPE. So far I've had one test report that it's now pitching accurately on an Atom N270. I don't have access to one, so more testing would be welcome. Even if it holds good with further testing, I figure that's just a workaround, not quite a fix. Beyond that I'd welcome theories or dissertations on just what the hell I might be dealing with here. cheers, Cal

installing a VSTi from a iso

by Fabio

I have a problem here installing a VSTi wich I have on various DVD-isos. Problem is that when i mount them I can't run the .exe because the iso gets mounted for root. I can run the .exe as root but than it will create a .wine folder for the user, obviously, and install it there. Anybody knows a way to mount the iso so my user gets rights to execute .exe-files?

Freewheeling needs love

by Jorge Salgueiro

Hello I'm a user of freewheeling and I would like to ask someone with programming skills: freewheeling is unmaintained and it would be great to have someone taking care of bugfixing and jackd compatibility at least. Would anyone like to do it? I have at least one nasty bug that doesn't allows me to use freewheeling with my oxygen 49: log at console: for each time I press a key: fluidsynth: warning: Ringbuffer full, try increasing polyphony! fluidsynth: warning: Ringbuffer full, try increasing polyphony!

Could I change config file so that: FreeWheeling library Could it be fw-lib-date like fw-lib-201001261324? So that my loops don't get all mix up? Ardour Could I record a freewheeling session directly to ardour were track is letter were loop is: track "a" track "dancepad_up" and so on... Help Key How do I change the help Key to the numeric keyboard pad slash? (My keyboard is a portuguese macintosh layout...) I think it should be at coreinterface.xml but I don't know the right name for each key. Looking at the xml I think I better buy a us keyboard ... I could even do freewheeling stickers that all for now. Cheers and thanks on advance! ____________________________________________ Jorge Salgueiro GNU/Linux: Free culture for a free society!

creating surround DVDs on linux?

by Jörn Nettingsmeier

hi *! i'm trying to get a couple home-spun surround mixes out to friends and customers. i wonder: is there a way to author dvds under linux with dts audio tracks? ac3 won't really suffice in terms of sound quality. better yet, i'd like to use five uncompressed pcm streams, and the wikipedia article on dvd-video seems to indicate it's possible - has anyone done it, and will consumer dvd players handle it? best, jörn

Music Made With Linux: Are You Washed In The Blood?

by Josh Lawrence

I was brought up in a southern protestant church (southern = bible belt in the usa), and this is a hymn that we used to sing very frequently called are you washed in the blood of the lamb. the only difference between this and what I heard growing up is that we had no instruments in our church - it was all 4-part acapella singing. everything you hear is run through rakarrack into ardour (even the vocals). honestly, my vocal tuning sucks and the mix sounds like shit, though I kind of like the guitars. however, I can tell you that bad tuning is nothing new when it comes to southern hymns :) http://www.hardbop200.com/misc/washed-in-the-blood.ogg someone said (it might have been johnny cash) that all you need is three chords and the truth. this song takes me back to my youth. for reasons I can't explain, I keep thinking dave phillips might like this one too, but I don't know why. enjoy. be gentle. -- Josh Lawrence www.hardbop200.com
