Hey,<br><br>Oops! I didn&#39;t know you were using Alsa Modular Synth! I assumed you were using AMSynth (Another linux synth)!<br>Thanks a lot Gabriel for that diagram! I will admit I&#39;m useless at modular &#39;synthesis&#39;!<br>

&gt; Hey Patrick,<br>

&gt;&gt;&gt; Basically your signal chain should go:<br>
&gt;&gt;&gt;<br>
&gt;&gt;&gt; Oscillators -&gt; Filter in -&gt; Output<br>
&gt;&gt;&gt;                         ^<br>
&gt;&gt;&gt;                         |<br>
&gt;&gt;&gt;                       LFO<br>
&gt;&gt;&gt;<br>
&gt; [snip]<br>
&gt;&gt;<br>
&gt;&gt; Not sure if the ascii came out correct. So what I need is a low pass<br>
&gt;&gt; that<br>
&gt;&gt; has two input connections? A CV input and a signal input?<br>
&gt;&gt;<br>
&gt;&gt; The LFO feeds the cv input and the oscillator/s feed the normal(?)<br>
&gt;&gt; input.<br>
&gt;<br>
&gt; Using AMS, here&#39;s a nice ASCII-art patch.  I&#39;m omitting<br>
&gt; unused ports, envelopes, and the MCV input, assuming you can<br>
&gt; figure that part out.<br>
&gt;<br>
&gt;    +------+<br>
&gt;    | VCO  |<br>
&gt;    = Freq |    +------------+<br>
&gt;    |      |    | Mixer 2-&gt;1 |<br>
&gt;    | Sine =----= In 0       |<br>
&gt;    +------+    |            |<br>
&gt;             +--= In 1       |      +------+<br>
&gt;    +------+ |  |            |      | VCF  |<br>
&gt;    | VCO  | |  |        Out =------= In   |<br>
&gt;    = Freq | |  +------------+      |      |<br>
&gt;    |      | |                  +---= Freq |   +---------+<br>
&gt;    |  Saw =-+                  |   |      |   | PCM Out |<br>
&gt;    +------+      +-------+     |   |  Out =---= Out 0   |<br>
&gt;                  | LFO   |     |   +------+   |         |<br>
&gt;                  |  Sine =-----+              = Out 1   |<br>
&gt;                  +-------+                    +---------+<br>
&gt;<br>
&gt; Note that at low freqs, the Sawtooth wave will easily overpower the<br>
&gt; Sine-wave, so you may have to play with the Mixer to get the mix you<br>
&gt; want.<br>

</div></div>Ok, There are a couple :-) of example ams patches to play with here:<br>
<br>
<a href="http://djcj.org/code/ams/" target="_blank">http://djcj.org/code/ams/</a><br>
<br>
Specifically:<br>
<br>
<a href="http://djcj.org/code/ams/dubstep-synth1.ams" target="_blank">http://djcj.org/code/ams/dubstep-synth1.ams</a><br>
<br>
You will need the full set of ladspa plugins from the default fedora repo<br>
to work with them. No beta versions in this lot.<br>
<br>
