Re: seeking basic info on making sounds and recording

You can adjust things with jackd settings. The -p value before -d is number of portS and the -p after -d is size of ports. Both must be powers of 2 afaik. The -p before helps with stability, if it's too low you can have notes that don't happen like what you described. The -p after can help with late...

Re: seeking basic info on making sounds and recording

I tend to use multiple soundcards. You almost can't avoid it. Your motherboard has a sound card, your video card, and you probably have a USB mic that functions as a soundcard. And if you're an audio type a USB or PCI audio device in addition to all that. A lot of times you have to select the card, ...

Re: seeking basic info on making sounds and recording

Audio via RCA, red is right, the rule of thumb. Therefor left is white. You need to set your software mixer levels. ADC for analog to digital converter (INPUT) and DAC for digital to analog converter (OUTPUT). Via something like alsamixer. Pulse is pretty default these days. If you don't want it, th...

Re: Any Suse/Rosegarden/MOX8 tutors?

After the ten minute mark I show some of the gui options, no CLI needed. Except that I was using cwm which doesn't have a menu to select things from, so I had to launch them from the CLI. And I mostly used the virtual keyboards for the eye candy. The MOX8 should appear like the virtual / software ke...

Re: Any Suse/Rosegarden/MOX8 tutors?

I don't know if this is what you were looking for. But something I did this morning in debian under cwm. http://www.youtube.com/watch?v=68dNginMNKY Just the basics to get you started. A/V sync gets off as I try to use larger and larger apps on that old box. And various annoying cell phone handshakes...

Re: Noise through JACK on MacBook

It could be that the USB device is drawing more juice than your USB bus can provide. Laptop USB bus's tend to be under powered to conserve battery life. Perhaps a powered USB hub with a higher amp rating could quiet the beast. http://www.native-instruments.com/en/products/komplete/guitar/guitar-rig-...

Re: Noise through JACK on MacBook

On one of my old laptops, the mic input and headphone output had shared elements. As in I could not multi-track, record something new while playing something old at the same time. Because the something new (input) would have bleed over from the something old (output). Perhaps this is part of what yo...

Re: M-Audio MidiSport 2x2 Problem

It could be that the standard usb power isn't high enough amps to fully power the device. You might try a powered usb hub to see if the blinking improves. But as you've seen midi events are reaching your system, so it works per say. Pulseaudio is a whole other topic. Suffice to say that you don't ne...

Re: M-Audio MidiSport 2x2 Problem

http://usb-midi-fw.sourceforge.net/ There's different chipsets and stuff inside, even though those many variants have the same outsides. So you might have to do some trickery, or it might work out of the box. The device page on the m-audio site shows OS X support, so it should work in linux. I have ...

Re: Doing a workshop for kids on making music using FLOSS

That sounds like a neat project. Just thinking to myself, that maybe it could be like a $60 per participant workshop. That does all that on a raspberry pi and at the end of it, they get to keep the pi. There's more spec-y devices out now than pi. But I'd jump on something like that just because I ge...

Re: Fender Mustang amp barely audible when recording[solved]

I really don't know, but I'd guess mic level vs. line level. In case you have to run it through a board that only has mic preamps. And there's a voltage difference between mic and line inputs. I guess it depends on what connectors are in use and all that. And I'm basically guessing as to why.

Re: Fender Mustang amp barely audible when recording

Has it worked the way you want before and nothing is different hardware wise? If you're using fluidsynth / qsynth as the input sound, there's a gain option there. The default gain on fluidsynth is barely audible in some distros. And make sure the volume from the keyboard is appropriate, changing my ...

Re: Separate host for Midi keyboard

Alsa is the driver for the soundcard. Jack is a layer on top of that. You can use both at the same time, from a technical standpoint, as long as nothing locks the device. Not much of an issue with current versions of stuff. You can even have the pulseaudio layer over jack over alsa. And various comp...
