			<content:encoded><![CDATA[<p></p><p>After I finished the 9700 I was looking for a way to test it as a whole. The one thing missing from the PAiA website was a test patch with a sound file, so that you can check to see if all the bits are doing what they should.</p>
<p>I think that my synth is actually working OK, and all the problems I had were just down to bad patch cables.</p>
<p>Here&#8217;s an image of my latest test patch, that tests the MIDI, OSC, modulators, filter, trigger, gate, and ADSR.</p>
<p><a href="http://www.stephenhobley.com/blog/wp-content/uploads/2009/08/patch.jpg" target="_blank">Click here for the patch image.</a></p>
<p>This patch uses the VCO modulator to create the rhythmic PW pulsing effect, then the VCF modulator in cycle mode to create a simultaneous slow rising and falling sweep. The MIDI Trigger and Gate outputs are patched through to the ADSR in the VCA.</p>
<p><strong>Note: I accidentally wired the switch backwards on the VCA, so even though it is set to &#8216;Cycle&#8217; it&#8217;s really in ADSR mode.</strong></p>
<p>And here&#8217;s the patch in action&#8230;</p>
<p><object width="560" height="340" data="http://www.youtube.com/v/6Uz_L9aLnpk&amp;hl=en&amp;fs=1&amp;" type="application/x-shockwave-flash"><param name="allowFullScreen" value="true" /><param name="allowscriptaccess" value="always" /><param name="src" value="http://www.youtube.com/v/6Uz_L9aLnpk&amp;hl=en&amp;fs=1&amp;" /><param name="allowfullscreen" value="true" /></object></p>
<p>I&#8217;m really impressed, this is with no effects or anything, just the synth. Even the Juno&#8217;s needed a bit of chorus to liven up the sound.<strong>Similar Posts:</strong>
