Y-ellow All. I know this is unlikely but I thought I'd better ask before I dismiss this notion too lightly. But has anyone managed to get any creamware DSP platforms working with ALSA? I've got a couple of old Creamware cards. A scope fusion and pulsar if memory serves. Between them there are 9 SHARC DSPs. Which would be very nice should they be able to be pressed into service under linux. I don't suspect so. Even under windows these things are locked down and locked out. I can find a lot of chatter about this but nothing conclusive. I even recall someone talking about running csound on one of these things many years ago. So I thought I'd tentatively ask just in case I'm missing something. Thanks in advance.

livecoding question

by Gregory Joyce

I like puredata for sound design because usually once that is set up it's fairly static. I don't really like "composing" in puredata though. So what I am asking is this: Is there some sort of nyquist-like program that will allow me to edit a text file which will send OSC or midi data to PD (or anywhere). Ideally you could have your 'score' up in vim and then the program would watch the file and apply the new information at the start of the next measure. I looked at CM but as I understand it, it is not real time at all.

Hello! And sorry, but this is not exactly ontopic. But does anyone else get Sandor's mails as SPAM/ I think all of them, for some time now, arrive as SPAM, and somehow every answer from the list to them, also gets marked as SPAM. Just wondering...

alsa sequencer port numbering

by Bob van der Poel

I've recently updated my system from Ubuntu 9.10 to 10.10. One unresolved problem I have now is the sequencer port number assignment. On a boot, sometimes it comes up as 20:0 ... other times as 16:0. I do have 2 audio cards on the system, but only one has a seq. bob$ aplaymidi -l Port Client name Port name 14:0 Midi Through Midi Through Port-0 20:0 Ensoniq AudioPCI ES1371 And in my /etc/modprobe.d/alsa-base.conf file: bob$ cat alsa-base.conf # autoloader aliases install sound-slot-0 /sbin/modprobe snd-card-0 install sound-slot-1 /sbin/modprobe snd-card-1 install sound-slot-2 /sbin/modprobe snd-card-2 install sound-slot-3 /sbin/modprobe snd-card-3 install sound-slot-4 /sbin/modprobe snd-card-4 install sound-slot-5 /sbin/modprobe snd-card-5 install sound-slot-6 /sbin/modprobe snd-card-6 install sound-slot-7 /sbin/modprobe snd-card-7 # Cause optional modules to be loaded above generic modules install snd /sbin/modprobe --ignore-install snd $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-ioctl32 ; /sbin/modprobe --quiet --use-blacklist snd-seq ; } # # Workaround at bug #499695 (reverted in Ubuntu see LP #319505) install snd-pcm /sbin/modprobe --ignore-install snd-pcm $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-pcm-oss ; : ; } install snd-mixer /sbin/modprobe --ignore-install snd-mixer $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-mixer-oss ; : ; } install snd-seq /sbin/modprobe --ignore-install snd-seq $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-seq-midi ; /sbin/modprobe --quiet --use-blacklist snd-seq-oss ; : ; } # install snd-rawmidi /sbin/modprobe --ignore-install snd-rawmidi $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-seq-midi ; : ; } # Cause optional modules to be loaded above sound card driver modules install snd-emu10k1 /sbin/modprobe --ignore-install snd-emu10k1 $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-emu10k1-synth ; } install snd-via82xx /sbin/modprobe --ignore-install snd-via82xx $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist snd-seq ; } # Load saa7134-alsa instead of saa7134 (which gets dragged in by it anyway) install saa7134 /sbin/modprobe --ignore-install saa7134 $CMDLINE_OPTS && { /sbin/modprobe --quiet --use-blacklist saa7134-alsa ; : ; } # Prevent abnormal drivers from grabbing index 0 options bt87x index=-2 options cx88_alsa index=-2 options saa7134-alsa index=-2 options snd-atiixp-modem index=-2 options snd-intel8x0m index=-2 options snd-via82xx-modem index=-2 options snd-usb-audio index=-2 options snd-usb-caiaq index=-2 options snd-usb-ua101 index=-2 options snd-usb-us122l index=-2 options snd-usb-usx2y index=-2 # Ubuntu #62691, enable MPU for snd-cmipci options snd-cmipci mpu_port=0x330 fm_port=0x388 # Keep snd-pcsp from being loaded as first soundcard options snd-pcsp index=-2 # Keep snd-usb-audio from being loaded as first soundcard options snd-usb-audio index=-2 I'd love to fix this one way or the other ... either get a reliable value for the port (which I always did under 9.10) or figure a way to set the value to something I want.

Denemo insisting on inserting drums

by Ken Restivo

I'm enjoying Denemo so far. But there are annoyances and frustrations too. For one, when I use the keyboard to input notes by typing "3" to input an 8th note, I get DRUM notes, not the instrument intended. And the notes are grey, not black. Why? http://restivo.org/misc/denemo3.png Is this a bug in Denemo or am I doing it wrong? -ken

Re: [LAU] Sampler project. First volley of questions

by Batz

Y-ellow Paul, Ronald 'n' all. Thanks for that. I can't quite tell what the CPU is on the tiny boards without powering them up. I don't have a manual for them or anything. However the slightly bigger one is a brand new ASUS I220GC. In box with all the bits. This thing apparently sports a celeron 200. I can't glean the speed from the manual but I gather it's at least 1.2 Ghz. The board has S/PDIF out which at least ticks that box. Apparently the celeron 200 is 64 bit? I'm not sure this would be fast enough for a fully fledged sampler but it might make a fairly wicked little synth. So excuse my ignorance but which would be the best audio distro to use? I was about to download slackware13. Slack has been my weapon of choice for years but if there's something better I should go with, then I'm all ears. Thanks in advance.

Text-based editor for Gigasamples?

by Ken Restivo

I'm going clicky-draggy crazy trying to edit a Gigasample with Gigedit. Hundreds of samples click, click, click, click, tedious, aauuugh!! Please, someone rescue me, with some kind of text file I can edit, and which will compile into a gigasample. I'm trying to edit a bass gig that I found. I want to change the release time on every sample. It should take 2 seconds with any text editor, and be 100% perfect. It's taking forever with this gooey thing, and is error-prone. -ken

OT: Italian University

by Renato Budinich

Hello list, sorry for the way off topic, but it's quite important... Italian university may not be here anymore, as we know it, in very few years. At my university in Trieste there will probably not be enough funds *next year* to pay wages, let alone heating, light and toilet paper. We have made this video which we would like to spread as much as possible... here it is: http://www.youtube.com/watch?v=IVHGFMR_N6o unfortunately it was done with propietary software, but it uses CC music from newgrounds.com spread it! cheers renato

Sampler project. First volley of questions

by Batz

Y-ellow All. Seems I've exhausted all hope of getting the A4000 running so I need to start planning out a system for a linux based sampler, sooner rather than later. So I'm hoping I can glean some initial answers here. Firstly I need to know if it's wiser to go to a 64 bit or 32 bit distro of Slackware? Assuming of course I get a suitable 64 bit capable mo-bo. Second question. Is it possible to get extremely low (read real-time) latency from an on-board or el-cheapo sound card, or do I have to look for something specific? If so is there a list of preferred sound card/devices? I have some older Hoontech DSP24 cards kicking around if they would suffice. These were quite a respectable card in their day and have more than what I need. IE: S/PDIF I/Os. Although if I end up using a lap top mo-bo then I'll need to buy a USB or PCMCIA or something? It would be nice if I could get away with on-board sound though. You can't do that under windows even using ASIO drivers but perhaps there's a trick under ALSA? The reason I ask is that I've got a bunch of teensy, tiny VIA based mo-bos. All-in-one. And they'd make a great little synth. Even if it was only a mono-synth. Obviously not powerful enough for my immediate needs but it would be somewhat cool to press these things into service as a small linux based synth. Thanks in advance. Very much appreciated. be absolutely icebox. ________ _ _ / ____|| | // Disgusting -> http://all-electric.com / /| |____ | |// The trusted _-_|\ / __ ____|| < name in / \ / / | |____ | \ \ non-sequitur \_.-*_/ / / |______|| |\ \ entertainment v All Electric Kitchen Music-> http://all-electric.com/music_downloads.html

edirol fa101 on differant rate that 48k ?

by Thomas Hedegaard

I have a fa-101. To change the samplerate you have to turn the knob choosing samplerate, then turn off the card on the back side wait a little while and turn it on again. Then change the samplerate in settings in jack and then start jack. Hope it helps.. I record in 88.2Khz on Ubuntu 10.04 via Jack, works very well Kind Regards Thomas Hedegaard 2010/11/16 Lorenzo Sutton <lsutton(a)libero.it> Hi try: > > - stopping jack > - unplug the card > - change the sample rate knob > - replug the card > - change the sample rate in jack settings (or in jackd command line) > - start jack > > Does it work? > > Lorenzo > > > Dragan Noveski wrote: > >> hallo list, >> i borrowed yesterday an edirol fa-101 in order to try if it will work on >> my sidux/aptosid mix. >> after some tweaking around and reading errors in qjack's messages window i >> get it to work really nicely in 48kHz mode. with all other sample rates >> which the card seems to be providing ( and is providing on my friends >> mac...) i could not get it to run. >> on a ffado page the card is listed as 'full supported', so i understood >> that also different SR should work. i also realized that turning the SR knob >> on the card does not changes nothing and that the SR is given in jackd's >> command line. >> could someone who is using this card please make some comments on this? >> >> cheers, >> doc >> _______________________________________________ >> Linux-audio-user mailing list >> Linux-audio-user(a)lists.linuxaudio.org >> http://lists.linuxaudio.org/listinfo/linux-audio-user >> >> _______________________________________________ > Linux-audio-user mailing list > Linux-audio-user(a)lists.linuxaudio.org > http://lists.linuxaudio.org/listinfo/linux-audio-user >
