Version 1.2 of IR, an LV2 convolution reverb plugin has just been released. This release is the result of many hours of stress-testing, and corrects some small but unpleasant problems you may have run into while using an earlier version. IR 1.2 is intended to be production quality software you can rely on. Please do upgrade to this version. Changes: * fix ir.ttl typo: "doap:license" instead of "doap:licence" * visual feedback of the progress of resampling operations * resampling operations are interruptible; you can no longer crash the plugin by deleting it while resampling a long impulse file * correct GTK2 version requirement and check it in the Makefile: at least GTK 2.16 is needed Source code is available from the usual webpage: http://factorial.hu/plugins/lv2/ir I wist to thank everyone who provided me with valuable feedback. Have fun, Tom

looking for a USB soundcard

by Cedric Roux

Hi Linux Audio Users, I am looking for a "USB soundcard" (if that has a meaning at all). Here are my needs: I want to record myself. I want 24 bits / 44.1KHz. I want a basic device with one stereo input plug (minijack or RCA) and one USB output (fast enough to send audio digital data to the comupter in realtime). I have the recording gear. All I need is an electronic piece of hardware that would pick up analogical audio signal and send digital signal to the USB input of my computer. It should be as simple as possible. I don't care about effects, more than stereo stuff, blinking lights or whatever. Just a box with one (two if RCA) plugs and the USB connector and so be it. It should preferably work with basic linux distro (ubuntu preferred) with no configuration at all. I plug the thing in the USB port and ALSA sees a new input device (whatever that means, I don't know much about ALSA but I'll learn; I don't want to bother with something else than ALSA like JACK, it's already painful enough, OSS come back! open("/dev/dsp") was perfect... (yes I'm old and lazy)). Do you know any hardware that does that? or that is close to that? (I can compile a new kernel, install drivers, and so on, it's just that with age come laziness.) I of course would prefer something that does not add too much noise to the audio signal. Well, just like any musician I guess... I can relax my needs. 16 bits if 24 bits is not possible, 48KHz if 44.1KHz is not common anymore and so on. (What? yeah I come from the past.) By the way, does 24 bits add a lot of comfort when it is about recording music? By the past I struggled hard to avoid saturation with my old 16 bits soundcard, that's why I wonder if 24 bits is better, a lot better, a little better or not better at all. Thanks for your help / suggestions, and happy music, Cédric.

[OT] guitar pickups: how to get separate signals for each string?

by Jörn Nettingsmeier

hi *! a guitarist friend of mine is looking for ways to get six separate outputs from a guitar, one for each string. he has a godin multiac, which comes with a 13-pin connector meant for the roland gr series guitar synthesizers - i wonder what would be involved in using the signal directly? if you've tried this, or know someone who has, please holler! next time i can get my hands on the instrument, i'll try some hi-z preamps (i guess it's a more or less raw piezo output)... also, i'd be interested to learn of replacement pickups for other guitars in humbucker or single coil format that provide six signal outs... best, jörn

by Nathanael Anderson

You want a hex-aphonic pickup with a breakout box like this: http://www.unfretted.com/loader.php?LINK=/profs/breakout hex-aphonic pickups systems are available from roland, graphtech,rmc, and a few others I personally have a roland gk2, gk3,and graphtech ghost lb-63 bridge. any of those would work with the above breakout box. If your not one for building a breakout box can be bought, but all the ones i've seen usually sell for over $300 a piece. Nathanael

Cakewalk UA1-EX does exactly what you describe and is plug-and-play recording with Audacity in plain vanilla Ubuntu. Fritz

Klick with jack transport: strange issues

by Mike Cookson

Hi all. Sorry for bad english. I have two issues. 1. klick as slave. I start it with 'klick -j'. The thing is that it skips (doesn't play by sound) huge amount of beats, each after other (or "at a run" - not sure, what sounds more correct). 2. Klick as master. It plays beats with correct speed, according to tempo map (imho, in interactive mode it also should work), but doesn't affect jack transport itself. Of course, i started klick before any other apps, able to be master (for some just disabled this feature).
