Is there an existing script or app for Linux that will recurse through my MP3 archive and check to see that the samplerate of every file is 44.1KHz so it only re-encodes those that don't match my spec?

Problem uploading sysex data to hardware synth

by Julien Claassen

Hello everyone! I've got a problem uploading some sounds to my Waldorf Microwave XT. It's an old device, but it's made to receive patches and wavetables. I downloaded a couple of MIDI fies containing the necessary SysEx data from the web. But when using aplaymidi to upload them like this: aplaymidi -p 24:0 bank.mid I get nothing for a few seconds and then messages like this get repeated a couple of times: [1393510.800523] dump_midi: 20 callbacks suppressed In the end I don't find any difference in my synth. question: is it the synth, the MIDI interface or ALSA/aplaymidi. My MIDI interface in this instance is a USB -> MIDI adapter, just shown as "USB MIDI Interface". It's twin is called "USB MIDI Cable". So I can't tell you it's make and model. So far they've both served me well. Any suggestions? Kindest regards Julien ---------------------------------------- http://juliencoder.de/nama/music.html

Anyone have any anecdotal experiences like this to share (horrible singers in the studio)

by Bearcat M. Şándor

http://youtu.be/OWoQpzdB5gs Has any of you had experiences like this in the studio? I realize this is exaggerated but i fear it may not be as exaggerated as i hope. -- Bearcat M.

Creating evenly spaced sample chains?

by Janus

Greetings, I'd like to chain samples into one new sample such that each input sample starts at a multiple of a given time value in the output sample (basically an evenly spaced concatenation). All input samples share the same format but differ in length. If a sample is longer than the given time interval it's tail shall be cut off (overwritten by the next one), if it's shorter, silence shall be added to it's end. Do you know of a tool or can you think of a command pipeline that would establish this (putting the samples on the grid in a DAW to export the result is too much work and also would make me feel stupid!)? I tried sox so far but it seems that it's not up to the task. Thanks vvd

OT comment on "band in a box"

by Pete Wright

On the escalating GUI vs command line troll-bait “discussion.” Interface concerns present to past: Voice and other “natural” or “semantic” approaches: Hal is breaking the surface; fully emergent soon. GUI (any kind): Now how am I going to keep an eye on Hal lurking just below the surface? Vi and Emacs: Wait a minute! It's the '80s again! Hal was lurking about in the shadows. I could sense it even then but was far too unclever to catch him. Bottom line: Hal is upon us. Do whatever you want to; it will seem fine. Be happy. Even more personal note: One of the advantages of advancing age is the many new flavors of paranoia to savor. Grins Pete

I will love to use it as an outboard effects unit for Front Of House in concerts, some questions: - Weight of the Quadra? - Will be a ExtraQuadra or Deluxe Quadra with multiple I/O's ? for multiple sends in console. - MOD Chain will support some ethernet protocol? regards, Federico PD: I write a small entry about it in : http://opensourcefoh.meteor.com/posts/JDiaz9TJYJWjwFW2P

Nepalese Song - improving mix?

by James Stone

HI Everyone, Here is a song I recorded with a friend of mine who is a Nepalese singer, and one of his friends who played the guitar and bass on the track. It has taken me ages to get round to finishing it, because I was having real troubles coming up with some drums that fitted the song OK. This is the current version, mixed in Mixbus. I would appreciate any thoughts on the song, and also the mix. https://soundcloud.com/jmstone/roughmix2/download/s-qgo8P James

Soundcard DSP2000 is not recognized any more

by Chris Bungue

Since two weeks I have a problem with my soundcard DSP2000 C-Port.(Hoontech) When I start the computer the soundcard is not recognized by the system. Sometimes it works when I restart the computer. But today I try to reboot the machine four times and the card is still not recognized. I haven't hat those problems before. The DSP2000has worked without problems for the last two years. I'm on ubuntu 12.04 kernel 3.8.0-14-lowlatency with KX Studio. The power LED is on, but the other four LEDs for the channels are out. I have try to start the driver in terminal: sudo modprobe snd_ice1712 but nothing happens. Any ideas? thanks for help chris **

delta 1010 (yes) / delta 2496 (no)

by David Santamauro

Hi, although sidetracked by life for a while, I finally got around to rebuilding my linux audio box. It's a stock fedora 18: Linux faure 3.8.5-201.fc18.x86_64 #1 SMP GIGABYTE GA-Z68X Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz 16GB RAM According to lspci -v, recognized are ... internal HDAC 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) Subsystem: Giga-byte Technology Device a102 Flags: bus master, fast devsel, latency 0, IRQ 48 Memory at fbff4000 (64-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel ... an HDMI HDAC (nvidia) 02:00.1 Audio device: NVIDIA Corporation High Definition Audio Controller (rev a1) Subsystem: Device 196e:0877 Flags: bus master, fast devsel, latency 0, IRQ 18 Memory at faffc000 (32-bit, non-prefetchable) [size=16K] Capabilities: <access denied> Kernel driver in use: snd_hda_intel .. the delta 1010 and 2496 05:00.0 Multimedia audio controller: VIA Technologies Inc.

Could it be because they share the same bus (05) that somehow they don't work together? Also, regardless of which slot the physical cards are inserted into, only the delta 1010 is ever exposed by ALSA. To be sure, I also confirmed that the 2496 does indeed work by inserting it into a different test box. Any insight would be appreciated. David

aseqdump without sensing FEH

by Julien Claassen

Hello everyone! I wondered, if there was a simple way to get an aseqdump style output without sensing information. I can only work on the console, so the clever GUI apps are not for me. I've seen, that arecordmidi can filter out active sensing, but it will display everything in hex. I can get this information, but I'm looking for a solution, that not only works for the learned brethren. :-) Any quick ideas on that? Thanks and warm regards Julien ---------------------------------------- http://juliencoder.de/nama/music.html
