Female Effects is a project consisting of new pieces for acoustic instruments and electronics, composed by female composers and curated by the harpist/performer Angélica Vázquez.

The musicians involved are: Yamila Ríos, Lula Romero and Maria José Belenguer from Spain, Kate Moore (Australia), Barbara Ellison (Ireland), Marie Guilleray (France), Fani Konstantinidou (Greece), Ji Youn Kang (Korea), Meiyi Lee (Taiwan), Wen Chin (Taiwan) and Marisol Jimenez (Mexico).

We made the second concert as a group, and this happened in Spain at 23~24th of November, 2012.

It was quite cool that all those female composers/performers got together and made a new music performance in combination between Acoustics and Electronics together. We played in two cities: first in Cadiz, and the second in Cordoba. I brought ‘Jing – A traditional Korean gong-like instrument-‘ and I felt good as well that I brought this Korean instrument there. The piece is called ‘Jing’ for Jing and Computer. 

This was also my first trip to Spain so that I wanted to look around too as much as possible, but this tight schedule was quite crazy. We slept almost nothing for two days because we needed to move all the time. The time for the soundcheck takes very long due to the technical needs and the amount of the pieces. But we had lots of fun.

When we perform at Cadiz, it was a part of the contemporary music festival Festival de Música Española de Cádiz. This means that we can expect the kind of audience who is quite interested in listening to the new music. However, the second concert was completely local concert. We played at Iglesia de la Magdalena, in a medium size old church. We were a bit worried if people would like this. One of my friends from Spain commented on my Facebook advertisement of the concert : “You play an electronic music in Cordoba??? ”

This scared me a bit, because we wanted to have some audiences involved. We worked hard to make this happen.

Then wow. There were tons of audiences from Children to Seniors. They really filled the whole church. No one left in the middle of the concert, rather they came closer and closer toward the stage. This made us so excited. People liked it very much and we had a very nice performance.

Of course we didn’t forget to have a party after all. Everyone was quite tired but we had some drinks and even went to a club to celebrate.

Now our organizer Angelica is making the second plan to Spain again. This time in Sevilla, and probably happens in April. I wish all of us to go, but in this moment we are not sure.

It is quite hard to survive as a woman Electronic music composer. There sill are prejudices that woman cannot handle computer and cables, and they would make a pretty music. This female effects throw a rock into that pool. We are very active composers mostly involving electronics to their works, have a new, charming idea on their works,  have knowledge and ability to realize it. So yes. We are female, but we are NOT feminists. We are those kind of people who just do what we’d like to do, and we met together in one field.

Should male involve in this group? Maybe and Maybe not. Not because we hate guys around here, but women composers would need a bit more of  support and more stages and opportunities to perform, and we believe that this group add a small action into that.

A Recent Piece performance “Hui-Mo-Ri” for a new instrument+Live Electronics

I haven’t taken care so much for few months of my blog, but I am happy to come back with this new video recording of my new piece, “Hui-Mo-Ri.”

The instrument was built by a friend of mine Wenchin. She’s a performer/artist, and this is the first instrument she has  ever built. Due to its complications that all the woods should have holes and metal strings/motors should be attached to them, and so on, it is quite fragile, but it worked at the performance. 🙂

The instrument itself should vibrate itself by the motor, but the connection was not strongly attached enough to do so. So the live electronics was quite essential. There are two microphones attached (a DPA and a Piezo) underneath the spinning wooden plates, and under the metal plate in the middles, there is a transducer that is supposed to create a feedback with the body.

I gave some additions to this: two sticks with the contact microphone attached. Those two sticks include metal pins and iron strings too that can interact well with the feedback.

Mainly you cannot hear the original ‘instrument’ sound there. I gave all additional processing with electronics. All are realtime processing programmed on SuperCollider(of course).

I was quite happy with the sound results and the structure. There is no very detailed score, but the entire structure that I composed.

In this première of the piece, I am playing with the percussionist MeiYi Lee, my dearest friend and we make a number of performance together as a duo.

Oh, and ‘Hui-Mo-Ri’ is one of the traditional Korean Rhythm structure, that is supposedly the fastest in tempo. It also means ‘blowing all together’ as a strong wind would possibly do.

I hope you enjoy.

**people who is around Utrecht in the Netherlands at 8th of Feb, This piece will be played by Sonolab Duo at RASA. Here’s the info.

How to install Archlinux on MacBook Pro 8,2[Part.2]

In Part 2, we are going to discuss how to install Xorg-server and work nicely with it. (Part 1) The problem is that, currently (if you have followed as Part.1) Xorg-server will run with framebuffer, not from the video card you have inside Mac. In Macbook Pro 8,2 there are two video cards ATI radeon and Intel. We are going to use ATI even though two graphical cards should work nicely with the strategy below.

The issue of not using video card without any tweak is because of KMSmode. On EFI system, it is using EFI system bootloader, which is different from bios one as in any os booting CD or Windows system. This will prevent the KMS mode to be on, otherwise the system won’t boot. Last time, we turn off the KMS setup by doing ‘nomodeset’ on the grub setting and this made the KMS to be turned off. However without KMS, Xorg-server won’t work with the video card, rather it will complain that the modeset is wrong for itself.

So what we need to do is
1. apply patches for Radeon video card on Linux kernel
2. compile the kernel for that
3. Create a vbios emulation which will be copied from any bootable CD
4. Set modeset to the other way around; turn on the KMS mode.

So I will go step by step.

1. Apply patches for radeon video card on Linux kernel.

Thankfully, there is a github of patches+kernel of ‘fooblahblah’ so that you can download.

There is PKGBUILD file included so that you can patch them. However I wanted to add some patches for macbook pro so that I
corrected the PKGBUILD a bit and added some patches. The patches can be found here with explanations.

2. Compile the kernel

Before doing this, make a back of your files /boot/initramfs-linux.img and /boot/vmlinuz-linux (no need if you compile those files with different name, which is recommended)

Now we can compile. If you have made the pkg correctly, then you can use

pacman -U filename.tar.bz

to apply the patch, and it will create a new linux-mainline img file for you.

3. Create a vbios emulation which will be copied from any bootable CD

Now we are going to make video bios from any of bootable bios cd.
I used archlinux liveCD for that.

This is how to;
-boot from the CD
-type 
 dd if=/dev/mem of=vbios.bin bs=65536 skip=12 count=1
 dd if=/dev/mem of=/boot/int10.bin bs=4 skip=16 count=1
-copy the vbios.bin and int10.bin into /lib/firmware/radeon and /boot
That's all.

4. Now we are going to correct the grub.cfg file.

This is a part of my grub.cfg file. Go down through the file and find the right place.

### BEGIN /etc/grub.d/10_linux ###
menuentry 'Arch Linux GNU/Linux, with Linux mainline kernel' --class arch --class gnu-linux --class gnu --class os $menuentry_id_option 'gnulinux-mainline kernel-true-a8ca6c35-c261-4b1c-9858-88a12804302d' {
 load_video
 set gfxpayload=keep
 insmod gzio
 insmod part_gpt
 insmod ext2
 set root='hd0,gpt4'
 if [ x$feature_platform_search_hint = xy ]; then
 search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt4 --hint-efi=hd0,gpt4 --hint-baremetal=ahci0,gpt4 a8ca6c35-c261-4b1c-9858-88a12804302d
 else
 search --no-floppy --fs-uuid --set=root a8ca6c35-c261-4b1c-9858-88a12804302d
 fi
 loadbios /boot/vbios.bin /boot/int10.bin
 echo 'Loading Linux mainline kernel ...'
 linux /boot/vmlinuz-linux-mainline root=/dev/sda4 ro loglevel=7 radeon.modeset=1 i915_lvds_channels=2 i915.modeset=1 i915.lvds_use_ssc=0 acpi_backlight=vendor vt.handoff=7
 echo 'Loading initial ramdisk ...'
 initrd /boot/initramfs-linux-mainline.img
}

Then you will be able to boot and your video card should work now with KMS mode. If you have an external monitor, your now it will
automatically work as well.

To install Xorg-server and setting up the monitor, there are many documents for instance, here

Some Remarks

– Do not update your linux kernel after you compile it. Freeze pacman into a certain date. I closed up ‘core’ repository on the mirror file for pacman. (/etc/pacman.d/mirrorlist)
– If anyone with another model of macbook pro with nVidia video card there is a patch for that too.
-Do not forget to install the video driver from pacman : xf86-video-ati, xf86-video-intel
-On the video card setup for Xorg-server, two videos are not working together so far. I use radeon.
