Change MIDI controller's channel from PC

by Federico Galland

Hi, My question is exactly the subject's. The controller in question is a MIDIPLUS Origin 49, connected to my laptop through a usb cable. Qjackctl lists a midi input to the controller so I'm wondering if there is any way to set the midi channel from the computer. In case there is a workaround, what I'm trying to do is to have the 8 knobs and 8 sliders on this controller mapped to, for instance, all the controls in calf organ. Then I could assign one of the sliders to control the midi output's channel (or the keyboard's preset), and control other features of the synth in question. The controller does have a way to change its output channel, but one has to use the piano keys for that, which means one would have to stop playing. Any ideas? Thanks for everything, and for those attending the LAC, I hope you have a good time there, I wish I could participate too. Fede -- Federico Galland <federicogalland(a)gmail.com>

OT: Windows experience..

by James Stone

Hi everyone, Thought I would just post a little slightly OT post just as general interest. I have been doing some fortnightly recordings of my attempts at jazz improvisation on this forum: http://improvstudy.prophpbb.com/ which I and some other musicians set up as a follow-on from the Gary Burton Coursera Jazz Improvisation course - which, incidentally, is very good (particularly for free) - although somewhat tough! For the last 2 weeks, I have been away on holiday, and then our house was being decorated - with my linux box, piano, and everything else having been packed away.. So I decided that for my next recording, I would use my (work) windows laptop to record my assignment (instead of qtractor, which I have found to be excellent for this) - thinking it should be pretty much plug and play. I did manage to record the piece, but it was much more difficult than expected: 1) my soundcard (focusrite scarlett 2i4) needed extra drivers to work with Win7. Under linux it basically works out of the box. After installing these drivers, there was very little control over the settings - I coul change the "buffer" from 0-10ms, but it seems from what it was reporting, that with a buffer setting of 10, the input delay was around 32 ms, and output 24ms or thereabouts -meaning round trip of 50+ms, which is way more than I had been trying to push it to on linux. 2) Started out trying Podium DAW for a long time - lots of hassle. Wouldn't play. In the end, I found it wouldn't play at all with the ASIO drivers for my card. Did work with the built in sound on the laptop, but whats the point of that? 3) Changed to Reaper - found layout very confusing (despite having used it before). Realised have to click the fx box to add a vsti! However, Reaper was generally a good experience. The one glitch was that it only intermittently recognised my usb keyboard - not a problem I had ever had under Linux - it fortunately worked long enough for me to record the piece once, but when I reloaded it, the USB input no longer worked - despite showing up under hardware profile.. I guess I could trouble shoot it, but I am hoping the linux box will be back up and running before I have to record the next piece!! So, overall, I found the switch from Linux-> Windows unintuitive, difficult and spent more time trouble-shooting than playing.. Sounds quite similar to what people say about going in the other direction! James

OT: Karlsruhe

by Jeff Sandys

I had an awesome time visiting Karlsruhe last year to attend the live.code.festival, and am bummed out that I won't attend LAC this year. I wanted to share some findings from my trip. * ICE - you can travel the 100 miles from the Frankfurt airport to Karlsruhe in an hour, and the trains run hourly. * OFFI - If you have an Android phone you can get directions from where you are to where you want to go using transit with this cool app. * German Museum of Mechanical Musical Instruments - is at the Bruchsal Baroque Palace, has a great collection of interesting instruments including the calliope from the Coney Island carousel. -- Jeff

[ANN] Qtractor 0.6.1 & Vee One Suite 0.4.2 - A pre-LAC beta release frenzy!

by Rui Nuno Capela

Howdy! As a pre-LAC release frenzy, Qtractor 0.6.1 (bitsy sweet beta) is out! the change-log for this release are mainly fixes: - New user preference option added as View/Options.../Display/Transport/Hold auto-scrolling (follow play-head) on edits (after requests by Holger Marzen and Louigi Verona, thanks). - All color chooser dialogs were missing proper titles. - Audio peak file re-generation and clean-up has been hopefully fixed and cache optimized (re. drawing audio clip waveforms). - Fixed initial session snap-per-beat setting on main toolbar. - Clip/Export...'ed files are now made persistent, no questions asked (after a ticket by Oliver Kester, thanks). - Portuguese (pt) translation added (by Esteban Viveros, thanks). The Vee One Suite of old-school also gets an interesting update. changes for the third proto-beta release are: - Badly named 'Noise' wave-shape oscillators get their band-limited treat option and re-labeled as 'Rand' (synthv1 only); also a brand new wave-shape 'Noise' is then introduced (now for real :)). - New user preference option, cf. Help/Use native dialogs. - An anti-denormal regression applied to the Phaser fx stage (affecting early proto-beta >= 0.4.0). all still available in dual form, as usual: - a pure stand-alone JACK client with JACK-session, NSM (Non Session management) and both JACK MIDI and ALSA MIDI input support; - a LV2 instrument plugin. Remember that both Qtractor and the Vee One Suite are free and open-source Linux Audio software, distributed under the terms of the GNU General Public License (GPL) version 2 or later.

I must be looking at the wrong page (plain text no coloured tables). Ta muchly. P.S. I'll be travelling by Eurostar to Paris, then TGV.

Audio measurement at LAC 2014

by Fons Adriaensen

LAC 2014 wil start in less than 48 hours, with what looks like a fully charged program of papers, workshops, installations and concerts. For those interested in audio measurements, there will a paper by Robin Gareus about audio metering (in a production context), and yours truly will present a workshop about audio measurements (i.e. the more technical side). The workshop will start with some essential theory (no rocket science maths), followed by hands-on practice. If you attend the workshop you can bring your laptop and audio interface [*] and have it calibrated against a precision RMS meter so you can later use it to measure other things. Make sure to have jaaa and jnoisemeter installed in that case. The best audio interfaces for this sort of thing are those having fixed or at least exactly repeatable analog gains. I'll also introduce some python extensions and code I've been using to measure audio HW and SW. For this you will need python, numpy, scipy and matplotlib. I'm using python 3.4, but things should work with 2.7 as well. See you in Karlsruhe ! [*] Internal audio interfaces are usually not worth the effort. Also, we'll have an assortment of XLR, TRS and RCA cables but no 3.5mm jacks ! -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities. (Cory Doctorow)
