=== Intro ===&lt;br /&gt;
&amp;#039;&amp;#039;&amp;#039;This is [[User:Noxiouspluk|NoxiousPluK]]&amp;#039;s Roland U-20.&amp;#039;&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
According to [http://www.vintagesynth.com/roland/u20.php Vintage Synth]:&lt;br /&gt;
* &amp;quot;The U-20 is nothing special. It is a digital synthesizer that uses ROM samples of pianos, brass, strings, bass, drums, etc. However it is built for professional use and is truly a quality instrument, even though its sounds may seem like dated-eighties synth pop cheese. It&amp;#039;s got nice piano sounds, but they&amp;#039;re not the real thing.&amp;quot;&lt;br /&gt;
&lt;br /&gt;
=== Issues ===&lt;br /&gt;
The U-20 has issues with it&amp;#039;s carbon conductive pads.&lt;br /&gt;
It is fairly simple to clean them using alcohol but this is a short-term solution and only really works if you play it often.&lt;br /&gt;
&lt;br /&gt;
A better solution is to apply a new coating.&lt;br /&gt;
[https://jimatwood.wordpress.com/2014/02/28/roland-u-20-synthesizer-key-contact-repair/ You can find a good writeup/tutorial on doing so here.]&lt;br /&gt;
&lt;br /&gt;
I (NoxiousPluK) cleaned this synth a few times with alcohol, and I&amp;#039;m happy to help repairing it again during a NURD-Inn, but I&amp;#039;m not willing to do it on my own :)&lt;br /&gt;
&lt;br /&gt;
It also seems to have some ESD damage, but when the firmware crashes its quite easy to reset it. I&amp;#039;ll document how to do this here asap (prolly the same NURD-Inn where it&amp;#039;ll get fixed).&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;If the synth is no longer in use, I&amp;#039;d like to see it returned to me including the flightcase!&amp;#039;&amp;#039;&lt;br /&gt;
&lt;br /&gt;
=== Sounds ===&lt;br /&gt;
{{#ev:youtube|Wkacf2TKAQQ}}&lt;br /&gt;
&lt;br /&gt;
&amp;#039;&amp;#039;This video is using a U-220, which has the same sounds.&amp;#039;&amp;#039;&lt;/div&gt;</summary>
