perfect install.....won't start

Hi :) if you just have less experiences with programming in any language, you might be able to program it yourself. The code has to compare the received data, if the first 4 bits of each received byte are set to 1001, resp. if the byte is > 8f hex and < A0 hex. After doing that you need to compare if the note is the key number that does the wrong velocity. A "note on" event looks like that: - first byte 1001 nnnn n is the channel - second byte 0kkk kkkk k is the number of the key - third byte 0vvv vvvv v is the velocity If you wish to have half velocity you need to shift the bits for velocity to the right, that will be faster than dividing by 2. There is a MIDI norm that's called "running status" which makes it a little bit complicated, but as far as I know ALSA MIDI sequencer intern don't use "running status" and as far as I remember it has a function that enables to detect note on events without testing bits. I have no experiences doing that stuff for Linux, that's why I can't write you such a rout, but someone should be able to do this in a few minutes, if you will ask in a special forum for stuff like that. You can get information about ALSA MIDI here: http://www.alsa-project.org/alsa-doc/alsa-lib/seq.html If I will find some time, I'll try some programming for ALSA raw MIDI. IMHO you seems not having done a lot of research for Windows, I guess stuff like that is default for non-free sequencers, you will have more trouble with Linux MIDI sequencers. Don't get me wrong, I'm only using Linux, resp. I have to repair my Atari ST because of the endless list of troubles that Linux MIDI sequencers will cause. If you will run all that MIDI applications Linux has got, first take care if it's possible to sync them, the way you need them to be synced, that will save pain. JACK transport isn't working very well. HTH, Ralf

We have some real linux oldtimers on the forums here that might be able to guide you though the hardware issue. It might be memory or temperature issues. I'll see if I can get them to give you a hand. Regarding the keyboard problem, there are many ways to skin a cat... none of which I have played with personally. You might be able to create an AMS patch, or similar to scale that single midi event. I'll look into it, but the best way is to play with it, and see what you can get done. There are some informative demo patches you can use to model your creation.

OK, I'e still not bothered fixing the graphics card, since it all works fine on the vesa drivers, but I have another problem now: I can use everything fine, all works smoothly, and then suddenly it dies. And I mean everything. Everything locks. I can't ctrl-alt-f1 to terminal. I can't even ping the computer from the network - it doesn't respond. It just freezes, for no apparent reason. It certainly seems like a hardware problem, since it happens no matter what software I'm using, and does it even if I'm not there. However, it seems unlikely to be related to the graphics card, since it's my understanding the vesa drivers are pretty bulletproof. So, any suggestions? Next problem then....I have a keyboard controller with a broken key - it outputs midi data with a higher velocity than it should. When using windows, I just grudgingly accepted there was nothing I could do about it, but the way linux is with everything so open, is there anything I can do to intercept the midi data and alter the individual velocities of keys? A jack compatible program? It still has touch sensitiivity, so it's really nothing more than dividing the velocity by 2. I realise I can do it afterwards in any midi sequencer, but I thought there's a chance there might be some way to hack it in linux Thanks again for all the help

Jajaja, lol Linux is not that difficult, you'll see. Take it easy! I often scratch my head after 2 years or three of using Linux, or GNU/Linux as you want. But that's because you never stop learning. Read the realease notes and believe it, it's very easy, well, let's say reachable. Don't worry about those things, people in 64Studio forums are very friendly and helpful. And some of them know an incredible lot. Pablo

oh, and apologies, I feel a bit rude having let you go to the trouble of writing instructions and not acting upon them. Sorry, but I'm still new to linux, and so I'm still in "if it ain't broke don't fix it" mode thanks again

thanks for getting back so soon. I changed xorg to use a higher resolution, still with the vesa driver, and I'm having a ball. I don't play games or have any other use for 3D, so I will probably keep using the vesa driver for a while, as the resolution is fine and I've had more than enough pain for today. Maybe I'll try Quentin's instructions tomorrow, or perhaps I'll wait till the new 64 studio comes out (end of the year?) to do a complete reinstall and try again. For now....I have midi in linux! Hurrah! I'm off to play Thanks for all the help

Hi again!

So,your graphic card is
GeForce 7300 GT, isn't it? Confirm with $lspci
I almost sure that this should work by installing packages from the 64studio repositories and changing the driver nv to nvidia in xorg.conf. I don't think what you suggest is a good idea, unless you are an advanced user and you know exactly what you're doing.

So my suggestion is that you should follow the last post by Quentin in this thread:
http://www.64studio.com/node/106

And hopefuly it will work, 3D and all.

Post back your experience

Cheers
Pablo

EDIT: Sory Quentin, I didn't see your message. I hope the issue is solved

I just saw your GPU model number. The nvidia driver that is included in 64studio as a post install option should support that card. Use Synaptic to install the nvidia-glx driver, and then manually change the line driver "vesa" line to driver "nvidia" That should do it...

is it a good idea to try to copy the driver and xorg configuration from my existing ubuntu intrepid installation?

hello again, I've decided to have another go at 64 studio, since the new ubuntustudio doesn't have a realtime kernel, and to be honest, judging by their website, the project isn't exactly buzzing with life. So, I've installed 64studio, same problem as before, but this time I tried changing the driver in Xorg.conf to vesa, and it worked fine. Graphical interface, though only 1024 resolution, but still enough to play about with. And guess what, knock me down with a feather, midi works with my EMU 0404 usb! I tried everything to get it working in ubuntu studio, to no avail, and it worked straight up in 64 studio. So, I'm pretty pleased with it so far, but....I can't work at 1024x800, obviously, so I've been trying to sort the drivers out. Endless problems. Nvidia installer is a waste of space. I'm doing my second reinstall now...and I'm wondering if it's possible to get the drivers from the ubuntu repositories? I've never had a problem with my nvidia card in ubuntu, so surely I should be able to download the driver from there? Any advice? Thanks

I have many times managed to resolve X-server problems in (Debian) Linux with this command - as root and in a text terminal (ctrl+alt+F1): dpkg-reconfigure xserver-xorg The blank screen is usually caused by faulty horizontal/vertical frequencies. Is your monitor a CRT tube? My monitors are and by default I am getting a horrible 60 Hz frequency which is a killer on my eyes. With the mentioned command I have been able to make the frequencies match at a reasonable 75 Hz frequency. The trick is to set the latter number - for example horizontal freq 31-75 and vertical 50-75 - to match. Even the "vesa" driver can be configured to use these frequencies - that is, if you're not into fast frame rates aka. games. After using dpkg - still as root user - give the command: init 1 You will be prompted for root password and logged in while the system is in single user mode. Then this command: init 2 X should start normally along with the entire system - audio, network etc. I hope this helps. Cheers, Tuomas

A bit of free time and I've given it another go. After trying to sort the problems with the nvidia drivers, and being so far out of my depth, I decided to do a complete format and reinstall....with my fingers tightly crossed. For some reason the first attempt died at 91%, so I tried again and this time it went all the way through. Got the blank screen again, and so tried dave's keycombos. Yes, I got into a terminal, and the message that comes up is 'Error: Microcode "bcm43xx_microcode5.fw" not available or load failed' then "core_up for active 802.11 core failed (-2)" Wonderfully descriptive error messages! God bless linux. I'm guessing from the 802.11 bit that it's a wireless problem and is probably irrelevant to the graphics situation. So, I tried apt-get update, but it's obviously not connected to the internet as it just says "reading package lists...done" instantly. It's a bit frustrating as ubuntu has no problems connecting to the internet, since I don't actually use the wireless card but am connected straight to the router by cable. So...anyway, to cut a long story short, a wise man always knows when to cut his losses, and so I have reluctantly decided to keep going with ubuntu studio until the next release of 64 studio comes around, since all I want to do it make music. Thanks for everyone's help, and if anyone wants me to check anything for bug fixing purposes, just reply here.

for not getting back sooner - I've been busy. I haven't had time to go near 64 studio, but sometime over the next few days I will try reinstalling and then booting into the console and doing apt-get. Thanks for all your help, I'll let you know how I get on. Oh, and I can't test on what those key combos do to the blank screen, since I don't get the blank screen now after installing the nvidia drivers from the website.

Hi cclofton. When you get to the blank screen, does. [ctrl] + [alt] + [f1] [ctrl] + [alt] + [f4] [ctrl] + [alt] + [f7] [ctrl] + [alt] + [backspace] do anything at all? being dropped into a teminal is one thing but a blank screen is strange. If you could get into a terminal you could install nvidia like this # apt-get update # apt-cache search nvidia You should see what you need now, amd64 or 486, I use! # uname -r 2.6.21-1-multimedia-486 # apt-get install nvidia-glx nvidia-kernel-2.6.21-1-multimedia-486 (or -amd64) matching your kernel. and accept what gets added. # edit /etc/X11/xorg.conf change "nv" to "nvidia" shutdown or reboot. I expected to look and find the Single user mode had worked. It's a new method to me but it looked fine. If you can follow Quentin's howto we will know if xorg.conf is there? If you can't follow the howto, can you get to xorg.conf from ubuntu? Did you get the the 64studio livecd? I am starting to wonder if xorg.conf there at all. I wouldn't give up, even if you have to download another image, It will be worth it. Cheers, dave

On the other hand, GNU is all about choice, and the freedom to choose. I know my choice, and I have played with the alternatives to make sure my choice is valid. If this issue is really giving you grief, then wait a bit for the 3.0 release... We should have it before the end of the year if all goes well (Debian wise) I have tried the drivers installed from the nVidia site, and it did not work for me the first time. Rather use the driver bundled with 64studio. Follow the instructions: http://www.64studio.com/install_guide_6 and do not miss the comment: http://www.64studio.com/install_guide_6#comment-54 to keep you in the graphical interface you understand for the installation of the correct drivers... If this doesn't work, you might have to reinstall 64 Studio to get rid of the drivers you injected into your system the nVidia way... Good luck

Hi cclofton. There is "single user mode" option in GRUB. You'll get no GUI, but you can solve your problem from there. We'll try to help you. But first: You have Ubuntu, right? In the same PC, right? So you have a dual boot, don't you? Boot Ubuntu and show us the output of cat /proc/partitions (~$cat /proc/partitions > thesearemypartitions.txt) Paste here the contents of thesearemypartitions.txt. (You can call these file p.txt for short) Also, paste here the contents of /etc/fstab Hopefully, we'll know something more about your install and give more precise instructions. Then, you'll have to do the following: (I know this is not the "64Studio way" and that you'll end up with a proprietary driver but this has worked for me and I think it's the easiest way to go). My proposal is that you should follow these steps: 1) Boot Ubuntu and download the nvidia driver to the Desktop. (Google: www.nvidia.com download drivers and choose the correct for your card under Linux). 2) Gain access to the Ubuntu System from 64Studio (single user mode) and install the nvidia driver. Further explanation to step 2 when you provide the above mentioned. Then you'll have it right, hopefully Pablo

I went to the faq, question 14, but without sounding stupid, how am I supposed to install a driver when I've got nothing but a blank screen in 64 studio? I don't even get a command prompt. I still have ubuntu studio on there, so I don't know if I should somehow copy files manually or what, but it's way beyond my experience - I'm a linux neophyte. Hope there's an easy solution, and thanks for the reply

follow the FAQ section regarding the nvidia drivers. 64 Studio uses the "nv" open source nvidia driver by default, but the 7### cards don't like it so much... The need the "nvidia" driver. Cheers,

Hello, I sent another comment about 10 minutes ago saying thanks for the replies, and that I'm downloading dsl, but my internet died and I don't think it went through. Anyway, I installed sysinfo on my ubuntu studio and that seems to give me most everything I could need, except I'm not sure about the motherboard. I'll just cut and paste what I've got 1 - AMD Athlon(tm) 64 X2 Dual Core Processor 5200+ 2 - My guess is "micro star international" - but as for model it says it's unknown 3 - GeForce 7300 GT I downloaded the install version - the 800mb iso file. I'm trying to download the live cd now, but my internet connection keeps dying. It happens whenever it rains! Therefore, if I don't reply, its not because I'm being rude, it's because I can't Thanks for the quick replies...again

If you have any problems finding out about your system download dsl, its only 50mb, and the livecd will print a verbose message as it boots, Graphics card, etc. Post info back including Pablo's request. http://www.damnsmalllinux.org/download.html I couldn't log on to 64 studio last night? when I did, I was getting lots of error messages on the page. It's fine today. I think the site might have been down for maintenance? edit: Cheers, dave.

First, welcome to this forum! I am a 64Studio user. Honestly, I don't think someone here can give you a simple solution if you don't provide some information about your hardware and the way you installed 64Studio. Hardware: 1) Your CPU model (type: cat /proc/cpuinfo Give the model name) 2) Your motherboard model 3) Your graphic cards model Installation: 1) The version you have installed Are you running Ubuntu or Windows right now? If you are running Linux it's easy for you to know about your hardware. I'll explain to you in the following post if you want. A very good test would be to run 64Studio-Live and check if it runs or not. For starters, tell us least H1) and I1) Cheers Pablo
