<br />
NOTE: Highest Video Resolution is 720p<br />
<h4>
Step by Step Instructions</h4>
<br />
1. Open the “Opportunities by Rep” report created in Lab 7-2 (Report builder design view)<br />
<div class="separator" style="clear: both; text-align: center;">
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi7AD-KGsKHRoxLr35v_zL-WxqbRO0m_D-_r3tYdxSLolKwxSQcij9dZ0wTXDH2OmAqB4rCLW5UAcfCiV6zPVX5TaC0NmL19iyFD9y-wc_xty6FzwLxTQpcaiaTxeTmwtVHgQ-dB9iXbV8q/s1600/01+L7-7+Dbl+Click+Add+Formula.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="450" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi7AD-KGsKHRoxLr35v_zL-WxqbRO0m_D-_r3tYdxSLolKwxSQcij9dZ0wTXDH2OmAqB4rCLW5UAcfCiV6zPVX5TaC0NmL19iyFD9y-wc_xty6FzwLxTQpcaiaTxeTmwtVHgQ-dB9iXbV8q/s640/01+L7-7+Dbl+Click+Add+Formula.png" width="640" /></a></div>
<br />
2. To Add a new formula column in the last column of the report:<br />
Double click on the “Add Formula” field in the Field Panal.<br />
(This opens up the “Custom Summary Formula” Dialog box)<br />
<br />
<br />
<br />
3. To Enter the formula to calculate the Win Rate: WON:SUM / CLOSED:SUM<br />
Use the [Summary Fields] and [Operators] buttons to construct the formula<br />
<div class="separator" style="clear: both; text-align: center;">

<br />
<br />
<br />
4. Run the report to see the result.<br />
<br />
Tips:<br />
i) You may need to filter the “Status” to see only “Closed” opportunities<br />
ii) Sorting by “Status” column should make the report easier to understand<br />
iii) Verify the result by comparing with your manual calculation<br />

<br />
<br />
5. Click [Save As] to save the report as “Opportunity by Rep with Win Rate”.<br />

Hi Guys,<br />
Introducing Linux Mint Simply Beautiful!<br />
Well, I have decided to start a new series in Bite-Size Linux, Day-by-Day to capture the beauty of using Linux Mint, its simple and elegant experience.<br />
All these while we are still Celebrating our Chinese Lunar New Year in Singapore.<br />
It has been a rewarding experience learning more about Video Editing in Linux. Jumping from a variety of tools to get things done up: RecordMyDesktop, XVidCap, PiTiVi, Kdenlive, and how Xdamage affect Video Editing.<br />
And most importantly, it's been a joy to be able to present you the finish product.<br />
May your quest in Linux made more enjoyable and interesting!<br />
Yours sincerely,<br />

</span><br />
<br />
<span style="font-size: large;">简介
</span><br />
<span style="font-size: small;">当我开始这个视频教程,原本想提供个简短容易的方法,解决氢鼓机无声或发出怪音的问题。如果在Linux里,你也在其他MIDI程序中遇到类似情形,可作为参考。
<br />有关桌面音频和视频体验LinuxMint11,一切运作优良。
<br />所有电影, DVD, Youtube, Grooveshark和MP3都是即装即用,精简无比。
<br />除此之外,是一个复杂的音响系统架构。
</span><br />
<br />
<span style="font-size: large;">问题与挑战
</span><br />
我们在这个简单的教程所面对的问题和挑战是氢鼓机无声音或发出奇怪的声音。各位,氢鼓机是一个优秀的软件。我的福气,当审查各种不同的Linux发行版的Live CD时,曾经亲自体验过。所以,我知道它精美之处,尽管我不是什么音乐高手。
<br />
直到我开始我的视频画面捕捉,我才发现它比我意识到的怪异。
<br />
<br />
<span style="font-size: large;">简速修改:
</span><br />
<a name='more'></a>把氢鼓机“音响系统”(Audio System)设置为“ALSA”,而非“自动”(Auto)。这可以很容易在“工具”菜单上选择“首选项”项目。(Tools -> Preferences)
<br />
步骤:工具 - >首选项 - > [音频系统]选项卡 - >“自动”更改为“ALSA”
<br />
<br />
现在,请播放,坐稳,放松和享受...Linux Mint: 添加薄荷香味的Linux。
<br />
<br />
<br />
<span style="font-size: large;">背景
</span><br />
其实,我的实际应用体验和桌面录影后,播放出来的结果是相反的!当我回播捕获的视频屏幕,才发现原来设置“自动”(Auto)会把声音录制,虽然当时我根本听不到任何声音,而将其更改为“ALSA”后却静音,即使我的确有听到声音播放出来。在这种情况下,我编辑了视频教程,以反映我实际的应用体验。
<br />
在此留信息传达于程序设计员和你,以便日后做与参考。
<br />
如果你有类似的经验,又或这视频教程帮助你解决这个问题,请让我知道。Guruwannabehttp://www.blogger.com/profile/02455596761472617500noreply@blogger.com0tag:blogger.com,1999:blog-6623367444537996954.post-47945140754986407842012-01-26T22:55:00.000+08:002012-01-28T17:02:17.148+08:00Fixing No Sound or Weird Sound in Hydrogen Drum Machine or Other MIDI program in Linux Mint<object height="480" width="853"><param name="movie" value="http://www.youtube.com/v/N4Nqp7FoG-M?version=3&hl=en_US&rel=0">

LinuxMint 11 64bit 2.6.38-8-generic<br />
Hydrogen Drum Machine 0.9.4.2<br />
<span style="font-size: large;">Introduction</span><br />
When I started this video tutorial, I thought I was giving you a short work-around for Hydrogen Drum Machine if you also experience a similar weird encounter with MIDI and Sound in Linux.<br />
As far as Desktop Audio and Video experience in LinuxMint11 is concerned, everything works excellent.<br />
Movies, DVDs, Youtube, Grooveshark, MP3s all works seamlessly out-of-the box.<br />
Beyond that... a complex Sound System Architecture awaits.<br />
<br />
<span style="font-size: large;">Problem / Challenge</span><br />
The Problem or Challenge we are facing in this simple tutorial is Weird sound, strange sound or no sound coming from Hydrogen Drum Machine. Hey guys, Hydrogen is an excellent piece of software. To my blessings, I have personally tasted it when reviewing various different Linux Distro Live CDs. So, I know it works beautifully eventhough I do not have much musical experience.<br />
Until I started my video screen-capturing did I discover that it's weirder than I realised.<br />
<br />
<span style="font-size: large;">Quick Fix:</span><br />
<a name='more'></a>The quick fix is to set "Audio System" to "ALSA" instead of "Auto" for the "Audio System" in Hydrogen Drum Machine. This can be easily done in the "Preferences" item in the Tools menu.<br />
Steps: Tools -&gt; Preferences -&gt; [Audio System]tab -&gt; "Auto" change to "ALSA"<br />
<br />
Now, Playback, Sit-back, Relax and Enjoy... Linux the Minty flavour!<br />
<br />
<br />
<span style="font-size: large;">Background</span><br />
In the Background, my actual user experience was recorded differently! When I playback the video screen-capture, Sound was recorded at the original setting of "Auto", though I actually did not hear any sound from the system, and muted after changing it to "ALSA", even though I did hear sound playing from my speakers. In this case, I have edited the video tutorial to reflect my actual user experience.<br />
I have included this information here as a feedback to those kind developers and programmers and in case you are also recording your desktop <br />
Let me know if you have similar experience and if this have helped you to fix the problem.Guruwannabehttp://www.blogger.com/profile/02455596761472617500noreply@blogger.com4tag:blogger.com,1999:blog-6623367444537996954.post-7645395923202121452012-01-23T18:50:00.004+08:002012-01-26T17:37:18.181+08:00使得Rosegarden和Qsynthesizer的声音运作开来<object height="480" width="853"><param name="movie" value="http://www.youtube.com/v/rR-gDWL0sDo?version=3&hl=en_US&rel=0">

</span><br />
我在LinuxMint11开始了Rosegarden(玫瑰园)的旅程,只是(要在不受版权所制止下使用MIDI软件作曲家)为我的视频教程,创造一些“独有的”背景旋律特效。
<br />
这任务有一丁点小挑战。在这个视频中,我记录了如何在Rosegarden和Qsynth里获得良好的成绩。<br />

<blockquote class="tr_bq">
<b>这个视频教程将向您展示变通的解决方案,让你在Rosegarden撰写音乐时能获得Qsynth为你播放。以便更容易的掌握Rosegarden和发挥你的想象与创作。</b>
</blockquote>
<a name='more'></a><br />
<br />
这都是一些基本的重要设置和故障排除指南。
<br />
<br />
<span style="font-size: large;">请记住:
</span><br />
首先:启用MIDI和选择ALSA _sequencer
<br />
其次:使用pulseaudio或ALSA
<br />
和
<br />
其三:在Qsynth装入SoundFonts - 例如FluidR3 _GM.SF2
<br />
<br />
并且:
<br />
在Rosegarden里
<br />
使用“管理MIDI设备”
<br />
把 “播放” 与 “合成器输入端口” 链接
<br />
<br />
稍后我们将看到如何进行此项目
<br />
<br />
<span style="font-size: large;">一些故障排除提示和技巧!
</span><br />
首先启动另一个音频视频应用程序,例:VLC
<br />
其次,启动Rosegarden前启动Qsynth
<br />
为了解决无声音问题,退出Rosegarden。再在Qsynth中:“还原”,"恐慌"和"重新启动" (Reset, Panic, Restart)
<br />
一旦解决了声音问题,不要重新启动或退出Qsynth
<br />
要修复Rosegarden里"回旋的“,“潜伏或落后的”,“有开裂和嘈杂的”声音,运行多个“音频”的程序,并调整它们的声音水平,或停止他们,又或退出并重新启动。
<br />
<br />
<span style="font-size: large;">请记住:
</span><br />
喝杯咖啡吧!
<br />
<br />
<br />
<span style="font-size: large;">解决问题时所用的技术:
</span><br />
“资源争夺”的规律
<br />
声音测试指标
<br />
压力测试/压力调整
<br />
压力的影响调整
<br />
均衡 /液平衡
<br />
<br />
<br />
<span style="font-size: large;">注:
</span><br />
问题/挑战:在前几轮的测试和实验,所有的设置都是正确的,但声音却没有播放,直到后来一些奇怪的声音传出。更多的测试和实验才获得更好的声音播放。但是声音却是不可预知的 - 它时有时无。可遇不可求!然而,更多的测试和实验揭示出一些技巧,我可以用它来播放声音。
<br />
<br />
1)VLC视频剪辑被当作一个声音测试指数,以测出Rosegarden可否通过Qsynth播放声音。在视频教程里,我启动了Rosegarden两回。第一回,VLC静音了,这表示Rosegarden不能通过Qsynth播放音乐。Rosegarden启动时的速度是另一种视觉指标 - 启动快是不利的。
<br />
2)使用VLC播放视频剪辑的另一个原因是启发资源争夺的目的,以压力测试音响系统,使不同程序之间产生协调。(这是一个观察,理论,结论的概念)。
<br />
3)Hydrogen氢鼓机是用于摆脱开裂,回音,滞后或嘈杂的声音。这是建于资源争用基础上的一个观察理论,使用压力测试和系统调整达到程序间的平衡,促使它们声音齐用。这类似校准。
<br />
<br />
<span style="font-size: large;">教程包括:
</span><br />
1)解决声音的问题
<br />
a)Qsynth和Rosegarden正确标准的设置
<br />
b)使声音播放 - 摆脱静音问题
<br />
c)调整系统声音 - 摆脱Rosegarden的回旋,滞后,开裂和嘈杂的声音
<br />
2)使用PulseAudio声音偏好,混合搅拌从各个程序的声音
<br />
a)单独控制每个应用程序的音量
<br />
b)控制整个系统的声音输出量
<br />
3)示范如何使用Rosegarden符号编辑器做撰写
<br />
a)绘入音符
<br />
b)循环重复播放音乐
<br />
c)循环重复播放时更改乐器,品尝不同乐器的音色Guruwannabehttp://www.blogger.com/profile/02455596761472617500noreply@blogger.com0tag:blogger.com,1999:blog-6623367444537996954.post-69783825870468087812012-01-19T01:14:00.000+08:002012-01-26T16:31:37.168+08:00Getting Sound to Play in Rosegarden and Qsynth<div class="separator" style="clear: both; text-align: center;">

LinuxMint 11 64bit 2.6.38-8-generic<br />
Qsynth: 0.3.5<br />
Rosegarden 11.06<br />
Hydrogen Drum Machine 0.9.4.2<br />
<h2>
Backgroud:</h2>
I started my journey into Rosegarden in LinuxMint11 64bit just because I
wanted to create some "original" background sound (using MIDI software
composer) for my video tutorial.<br />
It was a little up-hill task and thus I have documented in this video how I get sound to work in Rosegarden and Qsynth.<br />
What happened was, I googled quite extensively to fix this problem but to no avail, wondering all the while if my configuration and settings were right. In actual fact, all settings and configuration were pretty simple and straight forward. Only thing is to repeat the 5 troubleshooting steps below. Be patient and take a break if necessary but don't give up. Sometimes, I only need to perform step 1 & 2.<br />

<br />
These are some basic important settings and troubleshooting guidelines.<br />
<h3>
Remember to:</h3>
Firstly: Enable MIDI, and select alsa _sequencer<br />
Secondly: Use Pulseaudio or Alsa<br />
and<br />
Thirdly: Load a soundfonts into Qsynth - FluidR3 _GM. sf2 for example<br />
<br />
Also:<br />
Use "Manage MIDI Devices"<br />
in Rosegarden to<br />
Map "playback" to "Synth Input Port"<br />
<br />
WE Will see how this is done in a minute's time.<br />
<br />
<h2>
Some troubleshooting Tips and Tricks!</h2>
<ol>
<li>
Firstly Launch another audio-video application Example: VLC</li>
<li>
Secondly, Launch Qsynth before Rosegarden</li>
<li>
To fix the No Sound issue, Quit Rosegarden to "Reset", Panic and Restart Qsynth</li>
<li>
Once the sound issue is fixed, DO NOT Restart or Quit Qsynth</li>
<li>
To fix echoing, lagging, cracking and noisy sound in Rosegarden, Run multiple "Audio"
programs and adjust their sound level, stop them, quit and restart them
again</li>
</ol>

NOTES:</h2>
Problem / Challenges: All settings are correct but sound failed to
playback the first few rounds of testing and experimentations until some
weird sound came through. A few more testing and experimentations get a
better sound playback. Sound was unpredictable - sometime I get it and
other times not. It was more like a hit and miss kind of experience. Yet
much more testing and experimentation reveal some technique that I can
use to get the sound playing.<br />
<br />
1) VLC video-clip was used as a Sound-test Index to see if Rosegarden
would launch with Sound Playback. If VLC become muted at start-up of
Rosegarden like the first time it was launch in the video, then there
won't be sound feedback when composing / playback in Rosegarden. The
speed of Rosegarden is another visual indicator - launching fast is bad.<br />
2) Another use of the VLC video-clip playback is for the purpose of
Resource contention to Stress Test the sound system and enable the
successful negotiation of sound between the different programs. (This is
but an observation, theory, conclusion concept).<br />
3) Hydrogen Drum Machine was used for the purpose to get rid of the
cracking, noisy and sometimes echoing or lagging sound. This is an observation
theory based on Resource contention, Stress Testing and Tuning for the
system to feel the impact and Equlise and Equilibrate the various
different programs to use sound in unison. Something like Calibration.<br />
