RE: [linux-audio-user] midi filter to convert NRPN's to CC's

by Matthew Allen

The problem will actually be getting the NRPN's into PD. There are built in pd objects for [ctlin] which gives you 3 outlets, one for the Value, one for CC# and one for channel. There is a [midiin] object that might give you raw Midi info that you can parse, but like I said in my first email, I have never really used NRPN's so I don't know how you would go about getting them into PD. You could search the PD list archives here: http://iem.at/mailinglists/pd-list/ Or just join the list its self. It is full of a bunch of very helpful folks (many of whom are also here). David Mccallum has done a couple of abstractions dealing with NRPN's including it appears [nrpnin] and [nrpnout]. So this would be a good place to start. http://mentalfloss.ca/sintheta/html/downloads.html m. > -----Original Message----- > From: linux-audio-user-bounces(a)music.columbia.edu [mailto:linux-audio- > user-bounces(a)music.columbia.edu] On Behalf Of Chris Pickett > Sent: Thursday, May 20, 2004 10:53 AM > To: A list for linux audio users > Subject: Re: [linux-audio-user] midi filter to convert NRPN's to CC's > > Matthew Allen wrote: > >>-----Original Message----- > >>From: linux-audio-user-bounces(a)music.columbia.edu [mailto:linux-audio- > >>user-bounces(a)music.columbia.edu] On Behalf Of James Stone > >>Sent: Thursday, May 20, 2004 12:07 AM > >>To: A list for linux audio users > >>Subject: Re: [linux-audio-user] midi filter to convert NRPN's to CC's > >> > >>I think you should be able to do it with pd fairly easily..

[linux-audio-user] Steinberg The Grand

by Carl Hetherington

Hi, Has anyone had any luck running Steinberg's The Grand under vstserver? vstserver works beautifully for the Native Instruments B4 and the Steinberg EP, but The Grand gets close and then wine starts complaining. I'll post more details if people are interested, but I'd just like to know if anyone has managed to get it going. Cheers Carl

[linux-audio-user] alsamixer and the audiophile 2496

by luis jure

ok, i guess you can tell me the truth now: does anybody really understand all those "items" appearing in alsamixer for the audiophile 2496 ? or am i the only ignorant? i only use the analog input and output, by the way. the card is simple enough, and for me it "just works", but i really have no idea about these: IEC958 --> you can switch between IEC958 I, Digital and H/W In from 0 to 7; what's all that supposed to mean? IEC958 Multi and IEC958 Multi 1 --> two sliders that don't do nothin' i can see/hear... IEC958 1 --> similar to the other one above, and equally mysterious. DAC and DAC 1 --> well, at least i understand those two... Deemphasis --> hmm... i don't understand this one either, but i don't care much for whatever it is. i think. H/W and H/W 1 --> switches between PCM Out0, H/W In 0 to 7, and IEC958 I; if i choose H/W In 0 i can monitor while recording but no playback, choosing PCM Out0 it's the opposite. H/W Multi and H/W Multi 1 --> sliders, no idea what. Multi to Multi 9 --> a series of sliders, also no idea. Multi Track Internal Clock --> switches between different clock rates, don't know what's its use. Multi Track Peak, Multi Track Rate Reset, etc --> another set of sliders of unknown nature. as you can see, alsamixer is mostly a complete and obscure mystery for me. could anyone explain what does all that mean? or point me to a document where it's well explained? what i would like to do, if possible, is: - being able to monitor both while recording and playback without having to change the mixer configuration - record (with arecord, for example) from soundcard output; that is, capture what's being reproduced. - control analog input volume while recording (i can only see playback volume). please excuse me that i'm being so ignorant and stupid, but i've been using linux for only six years, alsa for only five, and this card for only one year, so i'm still a newbie. best regards and thanks for your attention, lj --

[linux-audio-user] midi filter to convert NRPN's to CC's

by Chris Pickett

Hi, I have a synthesizer whose knobs send out NRPN data. They only have a 12-bit range (0 - 4095), not the usual 14-bit range. I'd like to be able to turn one of these knobs, filter the NRPN data into CC data (range 0 - 127), assign it to some arbitrary CC, and then send it to either some running MIDI-capable software or out to my CC-accepting drum machine, with as low latency as possible. So far I've found Div's MIDI Utilities for Unix. Are these tools the most appropriate for the job? Or are there other more recent things for me to look at? It looks like I'd have to write some code to get what I want with Div's utils, so I just want to check I don't do something totally redundant. In windows, MIDI-Ox handled it fairly well, but I don't need anything so complex, just a filter is fine. http://www.sreal.com:8000/~div/midi-utilities-for-unix/ Cheers, Chris

[linux-audio-user] Quick question about envy24control and the Delta 66 soundcard.

by Luke Yelavich

Hi all Just wondering whether it is possible to change the inputs and outs to either -10, consumer, or +4 in envy24 control, like you can with the Windows delta control panel? Thanks Luke -- Luke Yelavich http://www.audioslack.com luke(a)audioslack.com

The "generic driver mode" descriptors aren't fully compliant with the USB MIDI specification, because it doesn't have an AudioControl interface, which is mandatory. You can say that an AudioControl interface is meaningless here because the UM-880 has no audio function incorporated, only MIDI. That is true, but in this case the class-specific AC interface descriptor will only contain the header descriptor. Did you see a kernel/syslog complain about "cannot find HEADER" or something like that? The usb-midi OSS driver doesn't look for AC descriptor, so it can handle it. But as Clemens said, that driver is not supported by Rosegarden. Regards, Pedro

[linux-audio-user] S/PDIF input on M-Audio Dio2448

by Anahata

Believe it or not, I've only just (bothered to) get ALSA working on my system (Debian Sarge snapshot a couple of months old) I have a M-Audio DiO 2448, and the primary reason for choosing it was for S/PDIF digital input. That worked with the OSS drivers (paid for...) - now how do I control the S/PDIF input with ALSA? The driver module is snd-cmipci. -- Anahata anahata(a)treewind.co.uk -+- http://www.treewind.co.uk Home: 01638 720444 Mob: 07976 263827

[linux-audio-user] edirol um-880 configuration help needed

by Chris Pickett

Hi Clemens (or others, if you can help), I am trying to get my Edirol UM-880 to work with Rosegarden-4.0.9.7 and alsa-1.0.4. This is a rackmount USB 8x8 MIDI interface. I have a gentoo-2.6.5-r1 kernel with USB support compiled in. ------------------ /usr/src/linux # grep -i midi .config CONFIG_SND_RAWMIDI=y # CONFIG_SND_VIRMIDI is not set CONFIG_USB_MIDI=y ------------------ The first thing I noticed is that it doesn't work with the default Edirol driver, about which the manual says: ------------------ FPT technology will be used to perform high-speed MIDI transfer. We recommend that you normally use this mode. FPT = Fast Processing Technology of MIDI Transmission -- this optimizes MIDI data processing by making efficient use of the USB bandwidth according to the amount of MIDI data being transferred. ------------------ I get the following in /var/log/messages when I plug in a USB cable with this driver enabled in the hardware: ------------------ usb 1-1: new full speed USB device using address 2 midi: probe of 1-1:1.0 failed with error -5 ------------------ To change this, you have to follow the instructions in the manual to use the generic driver mode. Ok, fine. I'm guessing Edirol isn't likely to release specs for the fancy one, but I haven't gone about asking. Now /var/log/messages shows me: ------------------ usb 1-1: new full speed USB device using address 3 usb-midi: Found MIDISTREAMING on dev 0582:0015, iface 0 usb-midi: Found MIDIStreaming device corresponding to Release 1.00 of spec. usb-midi: Found IN Jack 0x10 EMBEDDED usb-midi: Found IN Jack 0x11 EMBEDDED usb-midi: Found IN Jack 0x12 EMBEDDED usb-midi: Found IN Jack 0x13 EMBEDDED usb-midi: Found IN Jack 0x14 EMBEDDED usb-midi: Found IN Jack 0x15 EMBEDDED usb-midi: Found IN Jack 0x16 EMBEDDED usb-midi: Found IN Jack 0x17 EMBEDDED usb-midi: Found IN Jack 0x18 EMBEDDED usb-midi: Found IN Jack 0x20 EXTERNAL usb-midi: Found IN Jack 0x21 EXTERNAL usb-midi: Found IN Jack 0x22 EXTERNAL usb-midi: Found IN Jack 0x23 EXTERNAL usb-midi: Found IN Jack 0x24 EXTERNAL usb-midi: Found IN Jack 0x25 EXTERNAL usb-midi: Found IN Jack 0x26 EXTERNAL usb-midi: Found IN Jack 0x27 EXTERNAL usb-midi: Found IN Jack 0x28 EXTERNAL usb-midi: Found OUT Jack 0x30 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x31 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x32 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x33 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x34 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x35 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x36 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x37 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x38 EMBEDDED, 1 pins usb-midi: Found OUT Jack 0x40 EXTERNAL, 1 pins usb-midi: Found OUT Jack 0x41 EXTERNAL, 1 pins usb-midi: Found OUT Jack 0x42 EXTERNAL, 1 pins usb-midi: Found OUT Jack 0x43 EXTERNAL, 1 pins usb-midi: Found OUT Jack 0x44 EXTERNAL, 1 pins usb-midi: Found OUT Jack 0x45 EXTERNAL, 1 pins usb-midi: Found OUT Jack 0x46 EXTERNAL, 1 pins usb-midi: Found OUT Jack 0x47 EXTERNAL, 1 pins usb-midi: Found OUT Jack 0x48 EXTERNAL, 1 pins string descriptor 0 found (length = 4) usb-midi: langid(0) 0x0409 usb-midi: langid(match) 0x0409 usb-midi: fetchString(2) usb-midi: fetchString = 13 usbmidi: found [ EDIROL UM-880 ] (0x0582:0x0015), attached: usbmidi: /dev/midi01: in (ep:81 cid: 0 bufsiz:64) out (ep:01 cid: 0 bufsiz:64) usbmidi: /dev/midi02: in (ep:81 cid: 1 bufsiz:64) out (ep:01 cid: 1 bufsiz:64) usbmidi: /dev/midi03: in (ep:81 cid: 2 bufsiz:64) out (ep:01 cid: 2 bufsiz:64) usbmidi: /dev/midi04: in (ep:81 cid: 3 bufsiz:64) out (ep:01 cid: 3 bufsiz:64) ------------------ Which looks a lot more promising.

If I disconnect the USB cable, there is no change in the rosegardensequencer messages. alsa-patch-bay doesn't show me the UM-880 either, and there is no change with or without the cable connected. Finally, '/etc/init.d/alsasound restart' doesn't fix things. So ... what am I missing here? I looked in various places but couldn't find any information about what I need to do. Cheers, Chris

[linux-audio-user] Realplay 8.0 and sfxload; life is strange

by Marv Smoak

On my system, I using Planet CCRMA vintage March 2003. Realplay version 8.0.3.421 and sfxload version 0.4.3; when I need to boot my system, I must follow the procedure below to get realplay to work when I load a soundfont to my sblive card. Today I had to re-discover this sequence for the N-th time so I wrote it down. I'm posting it here in hopes it will help someone; I don't understand why it works, but it does, on my system. How to get realplay to work after using sfxload to load a soundfont to a SB-Live card. (Assume you've done a reboot of system, logged in as a user to KDE.) 1-- Before using sfxload, start realplayer first. Connect to internet and open a location such as http://www.jazz.fm/liveg2.ra ; realplay plays the stream. 1.1-- I usually start AlsaPatchBay and AlsaMixer at this point; it doesn't seem to matter whether this is done at this stage or later. 2-- While realplay is playing the stream, load the soundfont; on my sys sfxload 4marv/soundfonts/FluidR3_20GM.SF2 On my sys, the stream must be playing. During the loading of the soundfont the stream playing stops and and realplay says "Buffering". After the font is loaded, hit the stop button on realplay and re-connect to the location. The stream will start playing again. After this sequence, I can quit out of realplay and restart is without getting the dread "cannot open the sound device..." message. If realplay is not up and actively playing a stream when sfxload loads the soundfont, realplay will not find the sound device. And my system must re-booted. Logging out and back in, does not work. The soundfont load does not survive the boot.
