Hi, I anyone is feeling creative and wants to take a stab at making a new animated gif logo for the quicktoots it would be very helpful. The old one is getting tired and I don't have any ideas for a new one right now. Cheers. -- Patrick Shirkey Boost Hardware Ltd.

I found with my Delta 44 card (which is great) that i couldn't quite get high enough levels recording guitar without some kind of pre-amp. mics definitely need pre-amping. Getting a mixer was my solution; its got mic pre-amps built in and there's plenty of gain available. > It seems like people are just using the ones > in the programs (like in Ardour). I use the mixer in Ardour to mix the playback of recorded material. I use my desk mixer to monitor the playback from Ardour and the sounds as they are recorded. there is a latency advantage here, too. You don't have to make the software do _all_ the work! I seriously thought about getting a MG166, looks like a good bit of kit and i like Yam gear, but i just don't need all those channels! (ended up with a rather cheaper Behringer, which is fine). > If I get a mixer with the "Delta 1010LT", will I need the ADA8000? > > Does the 1010LT already serve as an A/D D/A converter? As R.Wolff already pointed out, yes it does. Or rather, that's what it is, mostly. If you get one of these look for the "envy24control" soundcard software. ( its in the alsa-tools-gui package in debian). hope this was some help. Best wishes, G.

automated midi rendering to wav

by James McDermott

Greetings, I have a bunch of midi files, each containing some drums and instrumental parts, and I'd like to batch-render them to .wav. Any suggestions please? Obviously I'd like some nice-sounding results -- I've been trying out Apple's GarageBand to render some tracks and it does do a good job, but no automation unfortunately. Thanks! jmmcd

Intel-hda jack low latency howto

by Nathanael Anderson

A intel-hda jack low latency howto (by wirelessdreamer) I've seen asked many times on the list how to get intel-hda cards working with low latency, in duplex operation. Here is a full, step by step, on how I got 4ms latency. I'm using a Dell M90 with a Quadro fx 1500, attached to a docking station with a Maudio Delta 66 pci card (secondary card) in it, the binary Nvidia drivers and Compiz. So if you were wondering, it is possible. :) 1. Kernel (i'm not going to walk you through how to compile a kernel) (the last kernel before the big kernel lock regression) * wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.24.7.tar.bz2 * tar xvjf linux-2.6.24.7.tar.bz2 * cd linux-2.6.24.7.tar.bz2 (if you don't see it here look in the projects/rt/older/ directory) * wget http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.24.7-rt21.bz2 * bzcat ../patch-2.6.24.7-rt21.bz2 * wget http://pastebin.com/pastebin.php?dl=f6ad31838 * mv pastebin.php\?dl\=f6ad31838 .config.old * make oldconfig (build and install your kernel) 2. Module Options Add the following line to the file your distribution has its module options in (in ubuntu it is /etc/modules.d/alsa-base) options snd-hda-intel model=ref position_fix=1 enable=1 index=0 3. Mixer Options (VERY IMPORTANT ! ! !) enable capture/record elements in mixer without this jack can't play nicely with intel-hda cards 4. RT Permissions In most modern distros /etc/security/limits.conf is where realtime permissions are set, I added these 3 lines to it, and added myself to the @audio group in /etc/group @audio - memlock 1024000 @audio - nice -10 @audio - rtprio 99 5. Jack options I use qjackctl to set these put a check in Realtime Priority 89 Frames/Period 64 Sample Rate 48000 Periods/Buffer 3

Handling SF2 files and comparing sounds, feature requests

by Crypto

Hi, there are large collections of SF2 files that sometimes sound really great, sometimes do not. In most cases simply looking at the file size already helps to guess the quality of sounds, although it can be misleading if there are a lot of sounds stored in the SF2 file. But in some cases otherwise poor sounding collections contain real gems which one would not have expected. If I really want to get the sounds I like with the best quality I would have to dig through all collections I have and listen to all the sounds in them. Unfortunately, this takes a lot of time which is wasted in many cases as there are so many equal sounding sounds which were taken from one SF2 file and copied to another. Sometimes with very few if not no at all parameter adjustments. It is also very time consuming to handle all files manually, copy presets, listen, rate, re-arrange presets etc. Now I wonder if this could be done automatically. Firstly there would have to be a tool that extracts all sound presets (including drum kits) of a SF2 file and stores them to harddisc, then runs a kind of file compare tool on each sound preset. There are some tools that can create a graphical representation of what is in e.g. a MP3-file (moodbar and the like), so it means there could be something that creates a graphical representation of how "similar" sounds are. And if they are, label them as doublettes that need closer examination. If the presets are identical, doublettes could be deleted. If we can compare sounds by an algorithm then we can also do the following: "My sax sounds much too bright, I need a sax that is much softer sounding. I know I have it somewhere, but where is one stored and in which SF2 file is it?" We could have citeria for sound comparisons by labeling a particular sound as a reference sound that we rate "100% fuzzy" and another that we rate "not at all fuzzy", and when we let the tool examine all presets then we find all sounds that are "slightlier less fuzzy" or "similar" to our reference sound etc. These are things we do all the time with our ears and our brain: rate sounds, compare them. Do You know what kind of development is going on there? What could I do to make life simpler regarding comparison of SF2 sounds? Regards, Crypto.

Feedback on Phonic FireFly 302

by Petter Sundlöf

I'm considering picking up a FireFly 302 for my basic instrument/vocals recording needs at home. And I've not found any thorough info on how well supported it is besides "Reported to work. So I'd like to ask a few questions: - What kind of mixer interface will it have? Will it be usable? Properly labeled strips? Is it "ffadomixer"? - Does MIDI work properly? - Is there anything I can do to contribute? I.e. if I buy one, can I work with someone to improve support for it? Also, I've tried to find info on the difference between 302 and 302 Plus, and it seems it's only inputs. The chip should be the same, right (BridgeCo?)? The one I'm considering getting is a plain FireFly 302. Any feedback is welcome. Thanks in advance, Petter Sundlöf

[OT?] last night's gig

by Dave Phillips

Greetings, Had a gig last night with some old friends. Board recordings are available here: http://drop.io/ph4tpjw Songs are various, some blues, some originals, some Mose Allison, et cetera. The leads are by my friend Terry McClanahan, brush snare is played by my regular drummer Rusty Campbell. Some of the vocals are mine, some are Terry's. I play rhythm guitar and bass. No Linux involved, hence the [OT?]. However, *I* am involved with Linux, so maybe it's not utterly OT. :) Sure would be nice to have a Ken Restivo on keys... Btw, when I say "old friends", I mean *old*. Terry's the youngest in the group, he's 56. Rusty's known as El Viejo (he's 60+), I'm in the middle at 57. To paraphrase John Lennon, we may be old but we're not boring. (Well, we don't think so. Opinions will vary.) Best, dp
