my first multi-track recording project on linux

by Rusty Perez

Hi folks, I submit this to you with great trepidation because I know there are lots of problems with it, but, here is the first multi-track recording I've ever made with nama/ecasound. First, each of these four tracks were a first take of a song idea I had. The bass and percussion parts were basically composed on the fly. This is the first thing ever recorded on my linux box, so levels ETC. were untested. It was also the first time I've ever mixed with nama. Finally, there is some distortion in the mix and I'm not sure of its origin. Anyway, with all that said, here's my first baby step. Hopefully I've reduced your expectations to nothing so that you'll find something good here. :-) https://dl.dropboxusercontent.com/u/30068518/invisible-friend-first-mix.ogg Rusty

Shouldn't be, at least not for what I heard there. I have an old P4 (single core)2.4Mhz and 2.5G ram. and I could handle that (I've done 12 or so tracks) on Ardour. I do slide the latency, going low for recording and higher for mixdown. I use a delta 66 which looks the same to the computer as your 1010. System tweaks may help. I record with no effects of filters at all, just direct sound. On the plus side the levels were good, and the sound natural. -- Len Ovens www.OvenWerks.net

Transmittance #2.5 episode - live telematic online & offline hybrid performance, from Ljubljana

by Luka Prinčič / Nova deViator

Hi LAU's, we're doing this again, with slightly changed team then before. perhaps this is of interest to you. all music, half of the video, streaming, and more, produced using linux and free tools. if you have nothing to do on friday evening, you can help us shape an online performance! (sorry for ><, please >>) This friday a specially selected team will engage on-line with _you_ who will select and suggest various scenes to performers, musicians, programmers and visual artists. Transmittance is an interdisciplinary telematic framework, research and performance. It explores collaboration which is local, global, networked and broadcasted. It involves an artistic group of performers, visual artists, musicians and computer programmers to research performative possibilities of streaming, broadcasting and telepresence forging new types of performance and audience. With focus on critical and socially-aware artistic languages this work is based on asking questions about body, self, technology and society - in an effort to iniciate non-dualistic perspectives. Please join us on a three-hour journey with a modern (HTML5) browser (Firefox & Chrome preferred) Friday 21. june, 20:00 CET at http://transmittance.emanat.si or on-site at MSUM, Ljubljana with you will be the #2.5 live team: Loup Abramovici, Maja Delak, Claudia Fancello, Matija Ferlin, Janez Janša, Luka Prinčič, Maja Smrekar, Maja Šorli Programming: Jakob Leben // Light design: Urška Vohar Photography: Nada Žgank // Executive production: Saša Rakef see also: http://emanat.si/en/production/?tag=transmittance http://u3trienale.mg-lj.si/en/program-2/ Transmittance is produced by EMANAT institute Co-produced by MG-LJ/MSUM.

Re: [LAU] hardware midi control--footswitch? or Jack audio transport

Space is pretty much default for start/pause. (works in qjackctl and jack.transport anyway) Jack.transport seems to have the easiest batch of one key commands to use: "s : Start and stop transport. Aliased to [space]. l : Locate to entered time. Starting to type a number will also enter locate mode. i: Set skip increment to entered interval. z : Locate to start (zero). r : Erase and refresh screen. > : Skip forwards. Aliased to . and [right-arrow]. < : Skip backwards. Aliased to , and [left-arrow]." So looking at other programs where a foot switch might be handy and trying to fit more than one might be an idea. space and left and right arrow happen to be very common (space is used in unix all over the place). z is the odd one out. -- Len Ovens www.OvenWerks.net

hardware midi control--footswitch? or Jack audio transport

by Rusty Perez

Hi folks, If this seems like a stupid question, it's because I'm very new at this. Is there a way to control the jack transport system start/stop with a hardware controller or footpedal? I want to control jack, thereby controlling other jack aware applications which do not have implementations of start/stop via midi. Thanks so much! Rusty

I agree. Also, one generally wants system feed back as to where the knob is adjusted to. The keyboard interface doesn't really provide a way of doing that. The rasp pi GPIO is probably a better interface for that. DIY does allow the exact layout the user wants though... sometimes that is worth spending more on. Sometimes you just can't get what you want from the store. -- Len Ovens www.OvenWerks.net

Inside is a tiny circuit board and lots of switches. Figure out the lines that go to the space, left arrow, right arrow (or whatever you think would be useful). Most programs will deal with key strokes. If you want it to be separate from your desktop KB there are ways of doing that probably in X or use a raspberry pi and run netjack and jack_transport or jack.transport... Or no jack at all on the pi and just have it ssh into your computer and run jack_transport. The same thing can be used for making a foot switch to advance impress/lyricue/or other presentation SW for displaying lyrics or a chord chart for that matter. Very simple project... put pc board in box, put how ever many 1/4 inch jacks you want foot switches for. Get epiano sustain pedals to plug in (make sure they are normally open or changeable). The pc card will have two sets of contacts for scanning, so each switch will be connected one contact on each set. I normally follow the traces back that go to the switches I want. I don't know about now, but it used to be Yamaha and Roland switches were opposite... One being NC and the other NO. Take an Ohm meter to the music store :) (this one would work for sure: http://www.sweetwater.com/store/detail/KSP20/ as it is switch-able) Don't worry about running out of switches... 101 should be enough to keep your foot tapping happily. -- Len Ovens www.OvenWerks.net
