WX5 MIDI mapping

by Milan Lazecky

Hi, I am sorry for a beginner question, but your advice would be helpful.. I have an electronic saxophone, Yamaha WX5. I use with MIDI->USB, using Qsynth (through jack), the sound is working well, but every time I try to record midi footage, using either rosegarden or ardour3, the midi record is: - in strange tones (the melody is there, but notes are transposed for +32 or -32) (note that using Qsynth, or connecting with virtual keyboard, the notes are ok...) - when I try to transpose the recorded melody to normal scale, it doesn't play anything (yes, I map some midi instrument there, but it seems like if there is some strange volume=0 was set, or I don't know - but I haven't found a way to set it to other values) I know it is very messy question. But maybe you know what is wrong in my case.. maybe to try another software, or I miss some settings there? Thank you very much. Milan

3.10-rt kernels unusable

by Ralf Mardorf

Hi :) on my machine 3.10.6-rt3 and 3.10.9-rt5 x86_64 don't work properly. Linux 3.10.9 doesn't cause issues. The last kernel-rt I used before the 3.10-rt kernels was 3.8.13-rt14, not used for audio production, but for daily desktop usage without issues. When running 3.10.9-rt5 even a terminal can't be opened anymore. Xfce-terminal and xterm open without a prompt, Ctrl+Alt+F-keys don't work. A shutdown does start delayed and then takes an hour without completely finishing. Does a 3.10-rt kernel work for someone on x86_64 architecture without issues? The mobo is an ASUS M2A-VM HDMI with an AMD Athlon dual-core 2.1 GHz, BE-2350 and 4 GiB RAM. Only tested with Arch Linux, perhaps I should test linux-3.10-rt on Ubuntu Studio too, not done until now, because building takes around two hours. Regards, Ralf

You can learn something about waveguides here : http://en.wikipedia.org/wiki/Digital_waveguide_synthesis I confess that the maths are beyond me, my evaluation of the filter is empirical, i.e. I use my ears.

Do have all versions off Matrix-1000, 6, 6R have the same MIDI implementation?

by Ralf Mardorf

Hi :) since Wiki mentions that the "Matrix-6R and Matrix-1000 are both rackmount versions of the Matrix-6" and I'm writing a command line tool for editing the Matrix-1000, I wonder if sysex remote parameter edit parameters and values are equal for all three synths? At least the device ID for all three synths is the same, 06 hex. If there should be minor differences for parameters and/or values I could add a Matrix-6 and Matrix-R6 mode. I also wonder if regarding to the MIDI implementation different versions of the Matrix-1000 were released. AFAIK there are no different versions off the Matrix-1000 regarding to the MIDI implementation and sysex remote parameter edit parameters and values are equal for Matrix-1000, Matrix-6 and Matrix-6R. Is anybody aware about differences? Regards, Ralf

Asus/Ubuntu/Audacity searching a reliable usb-recordig interface.

by Jose van Rooy

Linux-friends,i hope you can help me soon with the find of my desperate long-time wish. I include here my letter in a HTML-code, because at first i mailed this letter to the wrong adress, so to get rid of all the headers on the Gmail, i found an app (BasKet Note Pads, Ubuntu)that can do that, but till now iḿ not able to get the entire visible text at-ones pasted into the writable Gmailbox-space, then till now i ownly know this HTML-method with the BasKet Note Pad. Wish you luck in searching your own free spaces in life and the support to other good-harted people in this rude world. And thank you.. Jose.*

MusE: Transforming midi foot controller programs to toggled CC values

by Tim E. Real

This may be of interest to anyone who has a midi foot controller which only sends out program change messages, who also has an effects unit or SW which can map CC to effect parameters/bypass/etc, and who has a desire to use the foot switches like a regular 'stomp box chain' for *TOGGLED* control of individual effects. MusE's "Midi Input Transformator" plugin now allows you to do it. I pushed a wee mod and some fixes to our SF git repository. It should appear next release. The repo may change soon. Here's an example setup which maps Program Changes 0 - 3 to CC num = (Program + 10) and CC val = (TOGGLE 0 / 127): https://dl.dropboxusercontent.com/u/53315356/Patch2ToggledCCTransform.jpeg The neat thing is, you can KEEP program changes that are above a certain number (Program 4 and above in the example), so that the very same foot controller can be used to change patches AND control individual effects. Common foot controllers have four Program switches and two Bank up/down switches, so by going to the next Bank (Programs 4 - 7 in the example), it can be used to switch Programs, then go back to Bank 0 (Programs 0 -3) and the switches act upon the individual effects again. Note that MusE currently allows mapping midi controllers to any LADSPA Rack Plugin parameters *except* the 'Bypass' switch. So if MusE *itself* is to be the effects unit, properly a 'Bypass' controller should be added. Cheers, Tim. www.muse-sequencer.org/

Custom UI development in Pure Data

by Heikki Ketoharju

Hi everyone! I don't know if this should be asked in LAD, but I'm fed up with Pure Data's own gui components, and would like to develop my own gui with something else (GTK? QT?). I don't have earlier experience with any UI toolkit, so I don't have any favourites. What is easiest approach to custom gui development with PD? I need something like list boxes and buttons with custom text. Nothing too special. Heikki -- http://heikki.ketoharju.info/en/ <http://heikki.ketoharju.info>
