Meaning, you can drag a blue square around and the events in the pattern are sequenced into it (when you release the mouse button that is). As you should by now know, the position of the events is translated into pitch and velocity. It's enough to play around with for a few minutes :) I recommend Will J Godfrey's 'Sweep Saw' Zyn/Yoshi patch. Try it out: git clone git://github.com/jwm-art-net/BoxySeq.git && cd BoxySeq && make && ./boxyseq Just don't expect too much. You cannot edit the pattern unless you're willing to experiment with C code (lines 63 to 84 of main.c for event pattern, lines 87 to 105 for boundary settings) and recompile and restart the program. you'll need jack, glib, and gtk development packages installed beforehand. still very early days here. Cheers, James.

New blues and soul-esque tracks, need recording, mixing and mastering hints!

by Loki Davison

Hey all, after listening to Roberto Suarez Soto's track I thought I should ask for some advice for my latest stuff too! :) This is the first time i've recorded the drummer or my new bass so i'm looking for hints. I'd like to get these tracks sounding really good. At the moment i've just got the our first recordings, no studio magic applied. http://yoyo.its.monash.edu.au/~loki/moons_of_saturn-three_weeks_in_albania.… http://yoyo.its.monash.edu.au/~loki/moons_of_saturn-frustration.mp3 Drums are recorded using two condenser in recorderman config. All recorded at the same time except the bass as we still don't have a bassist and so i'm playing guitar and bass. :) Bass is recorded from the line out of my bass amp into my sound card. The guitars are a Rickenbacker 620/12 string, 650C and 4004 Laredo bass. The ric bass is my latest purchase and i'm pretty excited with it. :) Any hints? How does it sound? Are the drums recorded ok? What would you do with compression, reverb, EQ, anything else to these tracks? Thanks Loki

JACK scope?

by allcoms

Hi LAU! Instead of just turning dials and moving sliders randomly, I decided it was time to actually learn how to do it properly and study sound synthesis via bristol and yoshimi and the help of manuals and guides (like the arp2600 user manual). To that I end I went looking for a good oscilloscope that supports JACK yesterday and was very disappointed to find out there isn't one, not one that I was content with at least. meterbridge has a scope but it has no display options and you can't resize the window. The only other jack-supporting scope I found that I got to work was ll-scope which required I run it through the dssi-jack-host. This had a couple of limited display options but again there was no option to resize the display/window. qoscc didn't want to compile under lucid ("Don't know how to handle this Qt major version" vs QT3- is it really a QT 2 or older app?) so I doubt it would work under squeeze or other modern distros and xoscope doesn't support JACK. Seems like a fundamental, gaping hole needing to be filled in the linux audio toolkit but hopefully there is a good one that is evading me or someone may be able to explain how to compile qoscc under lucid? I've already wrote to the xoscope author and requested he add JACK support. Thanks, Dan

does a pci-e x1 to pci adapter work with Linux soundcards and existing drivers?

by Niels Mayer

I'm just curious if something like this will work with Linux audio cards? http://www.beaglesoft.com/pcie2pci.htm ///////////////// PCI Express to PCI Adapter featuring PLX Technology PEX 8111 PCI to PCI Express bridge PCI Express x1 cards have been scarce since the introduction of the bus several years ago. We now offer a PCI Express x1 adapter for server or desktop PCs that converts PCI Express x1 bus to PCI. The adapter utilizes a PLX Technology PEX 8111 PCI to PCI Express bridge chip. It will accept standard or low profile PCI cards. As a generic PCI to PCI Express adapter it should work well with most PCI cards. This adapter allows you to use your existing PCI cards in the PCI Express slot of your mother board. It can accept one of the half height cards designed for 2U server chassis environments, such as a Fire wire or Gigabyte Ethernet card. The 32bit 33MHz adapter’s 4 pin connector is connected directly to the power supply of your PC. The heat generated by the card is very low. The adapter has a bracket with a large gap to allow you to plug things into the card. The adapter will also accept a full height PCI card if your case has the extra headroom to accept a higher card. ///////////////// the above cards, however, seem overpriced given they're available for about $28.00 w/ shipping from Hong Kong: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=220652485942 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=320574364611 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=220595038826 Niels http://nielsmayer.com PS: one useful additional feature such cards might provide -- since the pcie x1 riser uses an ATX-style 12&5v power connector, that means you could use a separate power supply from the main computer's to help isolate the analog section from computer noise.

SalamanderGrandPiano_V2 Released!

by alexander

Here's the changelog * Re-exported all notes with all lowcut filters removed and eased off some eq on some notes around C4 * Replaced all pedal noise samples, there are now two down and two up samples. * Increased ampeg_veltrack on release harmonics from A0 to C2 * Increased ampeg_release to 0.850 * Introduced a 44.1khz16bit and an ogg vorbis version Sfz for LS still hasn't come out of cvs just yet but hopefully soon.. I just got a mail from Andreas on the LS-devel list and he said that he has started to implement on_lo/hiCC# wich means pedal action noise soon works! The ogg vorbis version doesn't seem to work with LS either... Jeremy Jongepier has put the cvs version of LS on his PPA so ubuntu users should get it going fairly easily; ["Better late than never, I've uploaded a CVS checkout of LinuxSampler to my PPA:https://launchpad.net/~autostatic/+archive/ppa/+packages So Ubuntu users can now enjoy this great sounding sample pack without having to compile LinuxSampler from CVS. A little tutorial on how to set it up: http://wootangent.net/2010/05/the-salamander-grand-piano-and-linuxsampler-c… Thanks for this great sample pack! Best, Jeremy"] And, the links; http://freepats.zenvoid.org/Piano/SalamanderGrandPianoV2_48khz24bit.tar.bz2 1.3gb http://freepats.zenvoid.org/Piano/SalamanderGrandPianoV2_44.1khz16bit.tar.b… 466mb http://freepats.zenvoid.org/Piano/SalamanderGrandPianoV2_OggVorbis.tar.bz2 74mb and a Demo, the reverb is called mverb:http://h.imagehost.org/download/0388/SalamanderDemo

Rosegarden Program Change dialog box?

by Andrew C

Hey all, I came across this post while googling stuff about Rosegarden and Program Changes: http://www.mail-archive.com/rosegarden-devel@lists.sourceforge.net/msg12791… Was this ever implemented back into the main codebase of Rosegarden or does a patch exist for it outside of Chris Cherret's OpenOctave fork of Rosegarden? Thanks, Andrew.

rtirq and hardware

by Gabriel M. Beddingfield

I'm using Rui's rtirq[1], and when I boot into my system the audio card is /not/ properly prioritized. However, if I do `/etc/init.d/rtirq restart`, then it /is/. It also works OK if I force the script to sleep (e.g. `sleep 10`). For some reason, rtirq is being run just before the kernel creates 'irq/16-HDA Intel' (the sound card). Does anyone know how I can wait for that without throwing in random sleep times? Thanks, Gabriel

changing pattern in hydrogen through seq24

by Renato

Hi list, is it possible to write patterns in hydrogen and then sequence them in seq24? (Instead of sequencing single basedrums/snares or whatever directly in seq24) thanks renato
