Hello. Convolution reverb might not be a best approach. The impulses I have seen (including at Noisevault) are puzzling. One impulse has square wave impulses. Another has exp decaying step impulse. Third has something close to sinc impulse. What is the "correct" impulse type? How the reverberations differ in the above examples if all have sampled the same device? Worse: The big Eventide impulse response archive at Noisevault has a sample with good impulses in left channel but fuzzy impulses in the right channel. -*- I will code Dattorro's plate reverb first, because it is close to Lexicon plates. I have coded it already but controls are missing. I'm sure it can be already found as a plugin written by somebody else (google it) but I will spend time in matching the response with Lexicon plate responses found at Noisevault. One of Creative's reverb (the one described in DAFX 2000) is similar to the plate reverb. I will write that kind of plate reverb as well.

Well, PureData might be what you need. see puredata.org cheers, Peter Anthony Baxter <anthony(a)interlink.com.au> wrote: >Hi there, >I'm looking for software for driving a sound system during a live >performance (of a play).

[linux-audio-user] Re: DeMuDi unusable on widescreen nVidia

Possible, but not without a struggle. Does anyone know how to get nvidia drivers loaded for the 2.6.9-multimedia-686 kernel? I've tried 3 or 4 methods and haven't gotten it. Says something about VMALLOC error. I've made significant progress though. At this rate maybe I can restart all over again with just DeMuDi and get the video working from the start... Jon

RE: [linux-audio-user] Switching from a MOTU828mk2 to RME Cards?

by Reuben Martin

This is quite a big leap your making. As much as I like to promote Linux based pro-audio, you should make very sure that changing out your entire system like that won't cause you problems. >I am gearing towards an RME Hammerfall card >and a behringer A8000 adat interface. I would rather recommend buying the Alesis AI-3 if you want to use the ADAT interface. This gives you more freedom to use various preamps. (IMO, berhringer's preamps suck) If you've got money you may want to invest in a nice preamp. http://www.soundpure.com/browseProductType.do?id=5 -Reuben

[linux-audio-user] [OT] disk recovery problem

by David Cournapeau

Hi there, It is a kind of OT, but I couldn't find any useful information, and I already wasted half a day on this problem, so I thought someone here would be able to help me. It seems like my partition table is messed up, and I am not able to mount all my partitions. For example, mount refuse to mount /dev/hda12 on any directory: when I do a mount -r /dev/hda12 /mnt/tmp, mount tells me that hda12 is already mounted, or that /mnt/tmp is busy. The partition is not mounted for sure, and I tried several other tempory locations, without any success. The "funny" part is that a fsck.ext3 /dev/hda12 doesn't give me any error when I check the filesystem (which let me some hope about the possible recovery). Basically, I think the problem is only coming from a wrong partition table, but I don't know how to recover the good beginning/end of the partitions (the partitions used for the OS itself seem OK, my linux is works flawlessly, "only" my last data partitions are not accessible anymore). All my partitions are ext3. Thank, and my apologies for the OT, David

[linux-audio-user] Using Midi Controller with the kamix (qamix) Mixer

by Esben Stien

By mistake, I first sent this to alsa-user I'm trying to use my bcf2000 controller to control qamix (kamix). My problem is what to put into the different fields. I've tried many combinations without luck. The physical FADER_TRACK_1 on my bcf2000 gives me this data with amidi #amidi -p hw:1,0,0 -d BA 09 01 BA 09 02 BA 09 03 .. and qsynth and ardour reports channel 11 input: Channel 11 Controller 9 Value 1 input: Channel 11 Controller 9 Value 2 input: Channel 11 Controller 9 Value 3 So far, great, but midicsv reports: 0, 0, Header, 0, 1, 384 1, 0, Start_track 1, 0, Tempo, 500000 1, 859, Control_c, 10, 9, 1 1, 920, Control_c, 10, 9, 2 1, 952, Control_c, 10, 9, 3 1, 1838, End_track 0, 0, End_of_file What is strange is that midicsv reports events happening on channel 10 while qsynth and ardour reports channel 11. I have no redirects set up anywhere. So I'm left with either channel 10 or 11, controller 9. I would assume putting something like this into the element part of the config file. <midi index="0" type="10" ch="10" param="09" sign="1" /> or <midi index="0" type="10" ch="11" param="09" sign="1" /> I've tried very many combinations, but none gives any effect to kamix (qamix) Type 7 is volume control according to the standard midi controller cc numbers. In the docs of kamix (qamix) it states that this number (7) is used for "note off". Well, I gave standard midi cc numbers a shot: <midi index="0" type="7" ch="11" param="09" sign="1" /> .. to no luck. I used qjackctl to connect the midi ports after each config change. I'm missing something fundamental here; do you have any idea? -- Esben Stien is b0ef(a)esben-stien.name http://www.esben-stien.name irc://irc.esben-stien.name/%23contact [sip|iax]:b0ef@esben-stien.name
