Steinway_IMIS2.2 soundfont (no loops fix)

by Roberto Gordo Saez

This is Steinway_IMIS soundfont, version 2.2. ftp://musix.ourproject.org/pub/musix/sf2/Steinway_IMIS2.2 This version fixes the issue with loops. I hope this is the good one and there are no more remaining major bugs. Marcos is a little busy right now, so he asked me to make this fix. He is thinking to make other improvements, so expect more updates soon.

[linux-audio-user] Sub-harmonic generator? (LADSPA or VST)

by Tim Howard

Hello, Does anyone know of a good plugin that will generate subharmonics? I would like to put a little more low frequency "oomph" into my bass track. Preferrable LADSPA, but VST would work, too. Thanks for any help! -TimH

Alternative FluidSynth GUI?

by Dan Capp

Research tells me that QSynth seems to be the only currently available/usable GUI for FluidSynth, but I get big xruns whenever I try and use it. FluidSynth itself doesn't cause me problems (I know because I'm able to use the FluidSynth-DSSI plugin fine in Rosegarden etc). The problem is that I want to use FluidSynth with Ardour3, but Ardour3 doesn't support DSSI plugins yet. So the only solution I have is to find a standalone interface for FluidSynth and then to link up using Jack. I looked at the old GUI 'FluidGUI' but it seems to be so old that it won't properly install on recent versions of Ubuntu. So does anyone know of: 1) A GUI for FluidSynth other than QSynth and FluidGUI?... or 2) An application other than the above 2 which would allow me to load soundfonts? Thanks in advance. - Dan

Re: [LAU] An appeal to famous artists?

by Aurélien Leblond

> My question/answer: "How much are you willing to do to make it happen?" Well I'm not exactly sure anymore to be honest, I didn't think my message would start such a rant! But after reading all the answered, two things seem to stand out: 1. A lot of the FOSS music software are not for the general public. I wouldn't agree myself (I mean, Ardour, Hydrogen or Yoshimi are as straight forward as a music software can be)... And for that, nothing much I/we can do but participate to the code (which I do when I can), make donations (which I do every year), provide feedback, provide bug reports, etc, etc, etc... And obvisouly use the software and produce some tunes! Which I do too: http://soundcloud.com/a-violent-whisper (Although now I realise that nowhere I say that it's completely recorded/produced with only FOSS softwares!) 2. More interrestingly, the "appeal to famous artists" didn't seem to be well received... What seems to come out though is that although the FOSS community seems to be good to produce software, we don't seem to be good at advertising it :) - Ardour has...49 followers on facebook... Nothing on the wall... - Hydrogen...94...and one entry on the wall... - Couldn't find a # tag for any of these on Twitter... I know I know, we are not advertisers, we are developers! But what if a small group of us (and yeah, including me :)) would do that? How do we go about that? We have loads of website/tools to share code and software (sourceforge, svn, git, etc..), but none to organise ourself into a community to create some kind of organised campagn of advertisement on social networks (or other tools)! What I have in mind is what was done by ThisOneIsOnUs... what they did for their production is exacty what we do every day for FOSS software...

[alsa] pci device ordering

by Tim Blechmann

hi all, (posted the same message on the alsa-user list, but without reply, now trying here) i have a machine with two pci devices of the same type. how can i ensure persistent device indices? the wiki [1] mentions a way for a way using vid/pid, but for pci devices it suggests to write a udev rule. [2] has an example, but it only describes how to set up the device names in /dev/snd. but how do i bind a specific device to an alsa device index (hw:X)? thanks, tim [1] http://alsa.opensrc.org/MultipleCards#How_to_choose_a_particular_order_for_… [2] http://alsa.opensrc.org/Udev

No duplex mode with the EHCI driver and USB hub. Is the problem solved?

by Pablo Fernández

Hi! A few days ago in the alsa users mailing list, Clemens pointed to a recent patch for the EHCI driver [1] [2] for solving the following problem: The current TT scheduling doesn't allow to play and then record on a full-speed device connected to a high speed hub. In connection with this, there was a discussion here some months ago [3]. Some users said that they were not able to get jack working in duplex mode . I also tried to prepare my sister's notebook with a UA25EX and duplex did not work either. I encountered the same problem in the laptop of a friend of mine. In both cases, the computers have an Intel 5 Series/3400 Series Chipset USB2 controller. Jack always says "broken pipe". I have not tried the patch yet but it seems to work if you read the whole thread in alsa-users. Has someone else tried? Joan? Jeremy?

What audio interface to use for a Linux-powered surround preamp?

by Johan Herland

Hi, (TL;DR: skip to "The main question...") I'm planning a hobby project to build an all-digital surround/hi-fi system. Regular surround/hi-fi systems convert digital input sources to analog in the surround processor/preamp, but I want to keep the signal in the digital domain as far as possible (by using all-digital class D power amps, aka. "PowerDACs" [*] that convert a PCM signal to an amplified PWM signal that is feeds the speaker directly through an LPF. The heart of this system is an all-digital surround processor/preamp that should do the following: 1. Switch between multiple digital inputs. (typically from HDMI or SPDIF) 2. Decode and/or upsample the input (if necessary) into a suitable format, typically 96kHz or 192kHz 24-bit PCM in 8 channels (for a 7.1 system). 3. Perform signal processing on the PCM signal, like room correction and volume control. 4. Output each of the 8 channels on separate digital outputs suitable for connection to the power amp associated with each speaker. AFAIK there are currently (very few or) zero preamps for sale that meet the above requirements. Requirement #4 seems especially hard to satisfy. I'm therefore planning to build my own preamp based on the following components: - A HDMI switch with audio split (SPDIF) and RS-232 control. - A Linux computer that controls the HDMI switch, and contains the audio processing software (e.g. a gstreamer pipeline doing the decoding and manipulation). - A suitable audio interface with at least 8 digital outputs. I believe this rig should be able to meet the above requirements. The main question at this point is what audio interface I should choose for the rig. Some points to consider: - Must work very well with Linux; bonus points if the vendor is Linux-friendly. - Must be able to output 8 channels of 96kHz/24bit PCM, preferably using AES/EBU or SPDIF (as that's what most digital power amps seem to accept as input). - USB, Firewire, PCI or PCI express? Which is more stable/supported? - Bonus points if it also has 8 analog outputs, as I want to prototype this on an analog power amp before investing in digital power amps. - Since this is still in a proof-of-concept phase, I'd like to spend not more than about $1000 on the interface. So far I've been browsing interfaces like: - MOTU 828mk3 (capable, but seems to be poorly supported by Linux) - RME HDSPe AES (very capable, lacks analog outputs, a bit pricey) - RME Multiface II + HDSPe interface card (has analog outputs, not sure if 1 SPDIF plus 1 ADAT can give me 8 channels of digital output in 96/24, pricey) - Focusrite Saffire PRO 40 (seems similar to RME Multiface II, but cheaper. Unsure how well it is supported by Linux) What other audio interfaces should I check out? Are there other things I should keep in mind when picking an audio interface? Have fun! :) ...Johan [*]: Examples of all-digital power amps include the NAD Direct Digital amps (M2 and C390DD), the Tact True Digital Amplification series, etc. -- Johan Herland, <jherland(a)gmail.com> www.herland.net
