USB has power even when PC is shut down?

by Florin Andrei

I upgraded my home PC to AMD64 dual core and the motherboard is ASUS M2N-E Socket AM2 NVIDIA nForce 570 Ultra: http://www.newegg.com/Product/Product.aspx?Item=N82E16813131022 I've an M-Audio Midisport 4x4 MIDI box connected to the PC via USB. On my old system (AthlonXP 2000, I forgot what kind of motherboard), when the system was turned off, everything went dark. But on the new system, the Midisport stays powered up even after the PC is turned off. I can tell it's up because the green LED is still blinking. The PC really is off, the disks are stopped, no moving parts move, everything is cold. Well, I guess this is more of a hardware question, but still, what's the deal with USB on these new motherboards? Is the bus still powered even after the system is turned off? -- Florin Andrei http://florin.myip.org/

qmidiarp??

by James Stone

I am having some trouble getting qmidiarp working. The log displays a lot of "unmatched event" messages, and if I select "discard unmatched event" nothing seems to go through, if I deselect this option, the midi seems to pass through, but no arpeggiator :( Any clues? James

Re: [LAU] USB has power even when PC is shut down?

by Thomas Ilnseher

Yes, usb power may be supplied via +5VSB (5V Standby power), even when the PC is powered down. This is in order to support "Power On By Keyboard" (when one is using a USB keyboard). All Mobos i came across that support that feature had some jumper(s) to select wether power is supplied by +5VSB or by the normal +5V rail. if that power is a concrn to you, RTFM to find this jumper. -- "Feel free" - 10 GB Mailbox, 100 FreeSMS/Monat ...

A program to chop up samples?

by Ken Restivo

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I remember stumbling across a tool-- or maybe it was a script in Python or one of the music languages-- that would take a WAV file and chop it up into a bunch of individual samples, with a way to adjust the hysteresis for threshold and length. I have used jSamp for making soundfonts, but it assumes that its input files have long silence between them. And that they have pitches to be assigned to note numbers. What I stumbled on, and am trying to find again, is one that did something similar but for shorter, noiser, percussive samples. Haven't been able to narrow down a Google search to anything useful. Anyone know of a program or script which does this? I suppose I could write it, but I'd rather not reinvent the wheel. - -ken -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFGPjiWe8HF+6xeOIcRAi5fAKCABJbFGgnK1stv0FQC87iDOwIw2gCfQyGK ckZN9WMFvKSSKBog8W4Zad0= =Xuob -----END PGP SIGNATURE-----

ANNOUNCE: PHASEX v0.10.0

by William Weston

Announcing the latest release of the Phase Harmonic Advanced Synthesis EXperiment (first release featuring a GUI), available for download (source tarball and FC6 RPMs) at: http://sysex.net/phasex/ PHASEX is an experimental softsynth for Linux/ALSA/JACK systems with a good mix of standard and experimental features. Here's a quick overview of what PHASEX offers: * GTK GUI: Every paramater is available through the GUI, with parameter names right-clickable for on-the-fly MIDI controller mapping and middle-clickable for parameter help. * 4 Osc / 4 LFO: Oscs and LFOs support multiple sources: MIDI key, tempo, envelopes, and inputs, all with selectable unipolar/bipolar scaling. Wavetable includes the basic wave shapes, both bandlimited and non-bandlimited. Per-osc and per-LFO transpose, pitchbend, and init phase. * Modulations: Full AM, FM, and PM (in this case, modulation of phase offset between left and right channels) routing with per-osc controls. Each osc can be modulated by any osc or LFO for AM, FM, of PM. Wave select modulation by LFO modulators is alsa available. * Filter: Modified Chamberlin filter with LP, HP, BP, BS, LP+BP, HP+BP, LP+HP, and BS+BP modes, distortion and retro (clean) types, keyfollow modes, ADSR envelope, and LFO cutoff modulation. * ADSR Envelope: Standard ADSR envelopes for amplifier and filter. * Chorus: Stereo crossover chorus with builtin phaser. * Delay: Stereo crossover delay with LFO modulation capability. * Key Modes: Mono smooth, mono retrigger, mono multikey (round-robin mapping of MIDI keys to individual oscs), and full poly modes are available. * Input Processing: Inputs may be routed to any combination of oscs and LFOs. Input boost allows weaker sources to be brought up to level of oscs. Envelope follower applies input envelope to output. * Sampling Modes: Supports undersampling and oversampling, giving control over the ever present quality vs. CPU tradeoff. Since this is the first public release of PHASEX with a GUI, feedback is highly encouraged. The project goal is to provide a synthesizer to experimental and professional musicians alike that is as easy and enjoyable to use as it is powerful. The next batch of new parameters and features will be a result of feedback from the community, so please, don't be shy. Cheers! --ww -- /* William Weston <weston(a)sysex.net> */

You've been a great help! > --ww Apologies for the delay in replying. I havn't used "patch" before, and have just edited the gtkknob.c file by hand, after doing a make uninstall for phasex. I don't know whether I needed to do a ./configure, and make again after patching the file, but I did, and after a make install, Phasex is working ok. No crashes. That's on Debian Etch, but as the change to that line has fixed the problem, it no doubt will fix it on FC5 as well. I don't think the problem was machine related, as I had the same problem with Phasex crashing when built on FC5 on the other machine. It would crash on the machine it was built on, but again, if I ssh into that machine from Etch, it works fine. The rpm for FC6 works fine, but jack-audio-connection-kit from Fedora extras appeared to be broken. I had to get an update from planetccrma for jack, before I could try Phasex on FC6. I've also got Kubuntu (breezy), and Slackware 10.0 on the same machine as Etch, which I've just put back onto testing/lenny. I suspect though there may be the same GTK problems as on FC2 with them. As I'm watching snooker at the moment, I'll have to check that out later. Nigel.

Re: [Freepats] Breaking silence and the road to free musical instruments

No need for spending lots of time making free | instruments, no need to care about fine tuning, and no need to wait | forever. | | But they are NOT FREE. And I'm not referring to the PRICE, I'm referring | to the FREEDOM. And yes, this is an annoyance for me, much more than the | price. They come with a license agreement: | | "you are NOT obtaining OWNERSHIP of the sound samples - you are in fact | purchasing a LICENSE to use the sound samples within your musical | composition" [...] | | I can only use them on the operating system imposed by the manufacturer. | I can't share modifications. My own compositions are a derived product, | so they are also infected, there is also a list of conditions which are | passed to my own compositions, I'm required to use loops "in a musical | context with at least two other instruments that contribute | significantly to the composition", just to mention one particular | condition. I can't publish my compositions under certain free licenses | of my choice, because they may be incompatible with the requirements. | | The requirements themselves are common to proprietary sample collections | and digital instruments (including hardware instruments).

(and retouch some things). I am too busy on making Musix GNU/Linux for now, but maybe I could help.

Alsa Modular Synthesizer 1.8.8 RC1

by Malte Steiner

You might read this several times, sorry for crossposting. In 2007 Karsten Wiese and Malte Steiner resurrected the AMS project to continue development. Now we proudly present the first release since 2004, the version 1.8.8 RC1. Everything runs fine on our computers but we would like AMS users to try this version and to report, maybe on the ams-user mailing list or bug tracker at sourceforge, when something is broken or patches sound suddenly different. Alsa Modular Synthesizer is a free open source realtime modular software synthesizer for Linux without compromises regarding sound quality. Its Jack compatible and can include LADSPA plugins.

I'm getting used to the way you talk :-) So you mean that the dramatic thing isn't expressed well with the guitar? Do you talk particularily about the guitar solo part? Julien.
