DAW REAPER : creating variation on Jingle Bells theme

DAW REAPER : variation on Jingle Bells theme
DAW REAPER : variation on Jingle Bells theme

Let us continue studying of DAW REAPER, today we will create small variation on Jingle Bells theme. As components we will use the same drums sounds and VST-synthesizer Genobazz 2, which is created by TEK’IT Audio. You can download archive with REAPER project, all sounds files and completed FLAC file of composition via this link : variation on Jingle Bells theme in DAW REAPER. For main melody I used preset Default of synthesizer and for basses Acid Tweet Arp preset. First lets create main melody with use of MIDI notes, then copy their block needed amount of times on its track; then we will use it for basses, by copying and replicating block on their track.

Next we will add accords to main melody : they are 3 notes, which are played together; additional notes are taken through the white key from main note or already placed note, they can be located in the same octave or in different from main note. They can be chosen by the ears, so that they will sound in unison with main melody; also, there is ability to read additional information about accords and their classifications. Then we add drums sounds to composition with use of snares and hats WAV files, which we place in needed places. After arrangement of composition, it starts to sound and now there is ability to continue work on it, making it more interesting. If you have questions about creation of variation on Jingle Bells theme in DAW REAPER, then ask them in comments, I’ll answer on them as soon as I’ll have free time. This is all for today, see you in the next lessons.

Sunday’s 130 km bicycle ride from Polevskoy to Snezhinsk

Birch forest on the way to Itkul lake
Birch forest on the way to Itkul lake

Yesterday I rode from Polevskoy to Snezhinsk, through Poldnevaya, Dautovo and Itkul villages. At the morning it was dry and warm, so it was nice to ride on the bicycle. Roads in Polevskoy at this Autumn day are covered with dirt, so at the exit from city bicycle was already also covered in it. In the direction of Poldnevaya road is clear, has small amount of traffic and has lots of downhills and uphills, so, there is ability to upheat yourself and gain higher rate of pedaling. Poldnevaya is readying for winter : fields are fertilized and plowed before intensive snowfall, for better harvest on next Autumn. Road upto Sverdlovsk and Chelyabinsk regions border is clear and dry, as before Poldnevaya village; after it and to Itkul lake it was not only broken this day, but flooded and covered with dirt, which quickly moves on to the bicycle.

Itkul lake between pines in Dautovo village

On the turn to Upper Ufaley this time I rode in the left direction, instead of right one. In this are asphalt is intact and mostly not plowed by heavy cars. I did not rode in these areas, first stranger on my way is Dautovo village, in the pine forest on the shore of Itkul lake, views here are picturesque : low leaden clouds run above surface of lake, Sun sometimes looks through them and sends its rays to surface in the half-darkness, on the distant hills unmelted snow still lays after recent freezes and snowfalls. Further on the way is Itkul village, in which there is ability to stray and make some turns in deadends and find right way. After it another small village lays, with steep downhills and uphills, on which stealthy cars riding from behind cannot be heard due to wind, playing in the ears; I did not remembered its name, because I flew through it very fast. 5 – 10 km forward it becomes clear, that serious closed area city is in front : there are straight electricity pillars on the sides of road with intact wires, clearness and tidiness on the road itself and on the area around it and roadblock in front with iron fence with barbed wire above it and, maybe, electricity current connected to it. This is Snezhinsk. Entrance in the city is strictly via permittances, because there is research and development nuclear center located in it. I heard and read about this, now I know this by myself. So, road to Vishnevogorsk lays around Itkul lake through Upper Ufaley city.

Near this road block I turned and rode back to my home, way went without problems, only near Polevskoy small rain started to pour and it became colder, before the darkness I was already at home. Overall I rode 130 km in around 8 hours at this day with all uphills, downhills, broken road areas and stops for bicycle tweaking and food eating. Next time I’ll rode to other area, where I was not before. 次の自転車イベントでお会いしましょう!

ESI U46 XL – professional external audio interface, that is designed for majority of studio tasks

External sound card ESI U46 XL
External sound card ESI U46 XL

Lets review professional external studio audio interface ESI U46 XL, which is designed for majority of sound recording tasks. It is created on base of preceding model ESI U46DJ. Card’s frontal panel has : balanced XLR microphone input ( this allows to neutralize all noises, which are added to signal during its movement in the cable ) with ability to switch +48 V phantom pwer, switch for choosing of linear or microphone work mode of the input, phantom power button and amplification level control knob; instrumental TRS 6.3 mm ( 1/4″ ) jack Hi-Z input, its Hi-Z or linear work modes switch and amplification level control knob; TRS 6.3 mm ( 1/4″ ) jack output for monitor headphones, their volume level control and power button. Back panel of sound card has : USB port and power adapter input; analogue TRS 6.3 mm ( 1/4″ ) jack mix inputs for left and right channels; 6 analogue RCA outputs ( which can work as 6 independent analogue outputs or as outputs for 5.1 channel audio system ); and 4 analogue RCA inputs. Sound card works on 48 kHz sampling rate with 24 bits precision and 100 dB range of digital-to-analogue and analogue-to-digital conversions. Body of card is produced from aluminum to increase its durability and to reduce electro-magnetic interference on its electronics.

For it drivers are released for Windows XP, Vista, 7, 8, 8.1 and 10 ( with MME, WDM and ASIO 2.0 interfaces and DirectWIRE support ) and Mac OS X 10.3 and newer ( with support of Core Audio ) operating systems, with which it can tightly integrate with modern DAWs : FL Studio, Cackewalk Sonar, REAPER, Avid Pro Tools, Ableton Live, Steinberg Cubase and others. Card is bundled with DAW Steinberg Cubase LE for PC and Mac systems. Package contains : ESI U46 XL sound card itself, USB cable, optical disks with drivers and software and user’s guide. All in all, this a good professional studio sound card, which supports majority of functions, except of MIDI and digital connectors; its other minuses are support of only 48 kHz sampling rate ( this is due to big channels amount and USB 2.0 bus speed capabilities limits reaching; but higher sampling rates are not always needed, for example, if sound will not be processed too much after recording ) and lack of volume level and clip indicators on its body. So, this interface should be bought only if it will be used exactly for functions, for which it is designed; if there is need to simply buy studio level or fully functional audio interface, then it is better to buy device, which has full spectrum of audio connectors and functions, for approximately the same price.

Its is very good light photo lens, which is produced in variants for majority of mounts of modern cameras and which has adequate price. For novice photographers and for video recording difficulties can be caused only by lack of auto focusing, electronic diaphragm settings and image stabilization ( which can be performed be camera itself, if it supports such function ). So, this photo lens is the most suited for experienced photographers.
