maybe i jumped too early

the simple addition of "-O2" to cflags made (a lot of) a difference ;)

Re: [LAD] ALSA Sequencer timestamp on event without scheduling

Thant's what I am doing[1] but I would like to know if there is a proper
method of doing so.

I suggest us to use this method as a standard way of doing it. This is
*necessary* for MIDI-BLE at least, where the packet provides timestamp
information.

If that's the case, we can patch some main libraries to use it if it is
available, and update ALSA Sequencer documentation.

You could set the timestamp field of the event, but why bother when
nobody is ever going to read it?

[LAD] ALSA Sequencer timestamp on event without scheduling

2016-09-16 Thread Felipe Ferreri Tonello 
Hello all,

I have a question. I would like to send sequencer events without
scheduling but with a timestamp information associated with. Is that
possible?

Thanks,
Felipe

hmm..

been trying converting the linkhut example to jack and ...

it plays well, links well with peers over the W/LAN, but dang it does 
draw upwards any cpu load chart over here :/~

who's willing to try this?

here's my (early) test code:
(please note that it includes the needed ableton::Link stuff verbatim):

nb. you also need asio-dev(el) installed (http://think-async.com/)

cheers

Re: [LAD] Tascam US-16x08 0644:8047

2016-09-16 Thread OnkelDead 

On my UbuntuStudio 16.04 (4.4.0-36-lowlatency) the streaming interfaces
(16xin & 8xout) works perfect with the stock driver / JACK.
The intention of my custom snd-usb-audio is to offer the build-in DSP
features of the US-16x08.
So I didn't made changes to the streaming interfaces but added some mixer
quirks to the stock driver.
Add. I did coded a custom mixer application (QT5) to control the EQ and
compressor function via those new mixer interfaces.

If you have problems with the streaming interfaces, I guess my driver wont
help you.

You may investigate the diff-file based on my changes in Ubuntu 16.04 which
you'll find  here   .

Note! Because I'd never investigate Fedora sources, I assume you should NOT
apply the patch to your kernel source directly.
