[linux-audio-user] New Virtual Keyboard Proposition

by Carlo Capocasa

Hi there! I've been using the Virtual Keyboard quite often and it's great, a regular computer keyboard can be a great two-octave non-dynamic keyboard. I don't see why it couldn't be used in concert settings, especially for electronic/synth-samples based music. The currently available Virtual Keyboard does have its issues though: * No more than about three notes can be played at once * Sometimes it works anyway, and precision goes down the drain; varying latencies up to a couple milliseconds result (To be fair this could be also be ZynAddSubFX's fault) * Usability: No way of saving the status of the various toolbars * Usability: Changing the Window with the mouse takes away the keyboard focus; this is WAY too risky to do on stage (Well it could be done but it WOULD be risky... Like performing a Hard Rock concert head banging seated on a chair suspended on fine china) * Not usable without X-Window * No Low-Level keyboard access; hence difficulty with various key layouts * Cumbersome TCL/TK customization Here is my proposition for a Virtual Keyboard that can turn any computer keyboard that is halfway precise into a fully functional Musical keyboard. 1. Terminal based version (Priority 1) 2. Lightweight but pretty (compare XFCE) GUI version (Priority 2) 2. Must operate on low-level keyboard access due to international keyboards and precision (Priority 1) 3. As close as possible to hard real time in dispatching MIDI events (Priority 1) 4. Keep keyboard focus at all times, even when switching windows or consoles (Priority 1) 5. Must be based on a compiled language or even assembly, it's got to be VERY precise and VERY fast! (Priority 1) 6. Uses ALSA sequencer (Priority 1). 8. MIDI Controllers with 'analogue' values could be controlled by mouse; two mouse axis equals to ranges of controllers to control at once; Mouse buttons can be used to switch controllers: No button pressed= MIDI Controllers 5 and 7, left button pressed=MIDI Controllers 29 and 7, both buttons pressed=MIDI controllers 78 and 43, etc. This must be configurable. Two mouse axis offer same functionality as hardware MIDI controller knobs (to hands to turn controllers at the same time). (Priority 2) 9. Configuration: Two categories of configuration options. 'Performance relevant' and 'not performance relevant'. Performence relevant controls must be accessible by keyboard and mouse input at once (remember, mouse is mapped to controllers, so no pointing and clicking). A good way to do this would be the F1-F12 keys. Press for toggle and Press+mouse for analogue input/scroll. Not performance relevant options are configured in a dialogue, which is saved to an XML file, which can also be edited by hand. (Priority 2) 10. No drop-down menus, ever. (Priority 1) 11. GUI Version occupies very little screen space (perhaps even an XMMS style MINI-Version) (Priority 2) 12. GUI Version skinnable (Priority 3) Wow... This would be so cool. Carlo

[linux-audio-user] alsa 1.10rc1 with emu10k1

by Shayne O'Connor

just wondering, seeing as the latest kernel RC now includes ALSA 1.10 rc1, if anyone has this version working for an emu10k1 driver? from what i remember, the 1.10rc1 drivers make the master mixer channel for the emu10k1 disappear ... anyone know if this is still the case, or if there is a patch available? shayne

[linux-audio-user] which patch for 2.6.13

by Antonio

Hi to the list, now that I've a stable setup with the vanilla 2.6.13.2 kernel I want to try to patch it for low-latency. I'm a bit confused on which patch to apply. I think I have to apply this: realtime-preempt-2.6.13-rc6-RT-V0.7.53-11 and maybe this: patch-2.6.13-rt14 but I'm not sure. I'm taking the patches from: http://people.redhat.com/mingo/realtime-preempt/older/ Sorry for the banal question. Best Regards, ~ Antonio

Thank you for the link!

Amazing! If I purchase FA-101 earlier, than you finish, I'll try to help. Dmitry.

[linux-audio-user] if no more fighting then have a MWL WIP

by R Parker

This song is a Made With Linux (MWL) Work In Progress (WIP). The tracks are there but it's unmixed. The players are Bill, Dana, and Joey Bailey and myself. Licensing All rights are reserved. Please download, send it to a friend but do not post on any servers, remix or sample it. In time we will release CC licensed multitracks and mixes. Now is not the right time for us. I'm releasing it to express my eternal gratitude for all the misinformation and fighting that happens on this list. I love this list. It makes me happy. http://www.iaxs.net/~rparker/happy-wip04.ogg ron __________________________________ Yahoo! Mail - PC Magazine Editors' Choice 2005 http://mail.yahoo.com

[linux-audio-user] Live SuperCollider BBCut2 breakbeats

by Mario Lang

Hi. Since people have been discussing breakbeat creation on this list recently, I'd like to show you something neat. http://mozart.soundportal.at:8000/delYsid.ogg currently features a SuperCollider3 BBCut2 demo. The code in use basically iterates over a selection of 150 loops applying all sorts of effects and different cut procedures. BBCut2 is a extremely cool extension for SuperCollider3. Just listen in, endless fun for people fascinated by the rhythmic aspects of breakbeat sounds. I'll probably let it run for at least a day or two. Stream created with SuperCollider3, BBCut2, JACK, oddcastv3 -- CYa, Mario

It seems like http://bugtrack.alsa-project.org is offline during few last days. Is it for me only?

[linux-audio-user] Juli@ card

by Bengt Gördén

Anyone got experience with this card? I'm about to get me a new card for my small studio and I thought of buying a Audiophile 2496 but my normal dealer didn't have that one so he recommended Juli@. I saw that ALSA is about to make a driver for it. regards, - Bengan ----------------------------------------------------------- - KTHNOC/SUNET/NORDUnet | http://www.sunet.se/~bengan | 08-7906586 -

[linux-audio-user] Long time listener, first time caller says hi!

by Doug McLain

Ive been very slowly putting together a blog oriented website to follow my home studio and music making projects. I've become most definately one of the biggest fans of Ardour and Linux audio, and have built my studio around it. http://nostar.net/ I figured now was a good time to post the site on LAU since this week we took quite an interesting turn. My anti-digital, refugee from the 60's, guitar genius bandmate finally coersed me into the analog realm. The fact that he bought all this hi-end analog gear sure helped too, this stuff just looks cool! (insert Tim Allen grunt here). Not as a replacement though, but rather as an addition to the input chain; to be used as an 'effect'. We are going to beat this one to death, it's gonna get real ugly! We are going to do some totally digital free recordings; then recording all tracks to the analog deck, and output them track-by-track to ardour; then record direct to ardour, output track-by-track to the deck, and back to ardour again. I'm also going to experiment with driving the signal into the deck at various levels, trying to find the 'sweet spot'. With a little luck, this will help break down the barrier between these 2 technologies, and maybe even squash some of the stereotypes associated with the technologies used, and the people that use them. I got the ball rolling and started familiarizing myself with the machine by taking some simple exported stereo wav files, and playing them into 2 tracks of the deck, then recording back to Ardour. Samples are available on the site. I was pretty impressed with the outcome. As far as the music is concerned, for the past year or so, it's been the 2 of us doing drums and guitar live, in an improv fashion. We then screen thru the session looking for worthy jams to overdub bass, vocals, leads, etc. Thats the entire lineup to date in a nutshell. We just scored a bass player this week as well, so it's gig time soon! Doug -- http://nostar.net/
