five that comprise a set of modules from CGS.&nbsp; It contains three different functions:<\/p>\n<ul>\n<li>A group of four passive attenuator pots<\/li>\n<li>Two <a href=\"https:\/\/pugix.com\/synth\/wp-content\/uploads\/2015\/07\/cgs64_vca.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">CGS 64 VCA<\/a> modules<\/li>\n<li>Two <a href=\"https:\/\/pugix.com\/synth\/wp-content\/uploads\/2015\/07\/cgs81_proc.pdf\" target=\"_blank\" rel=\"noopener noreferrer\">CGS 81 Voltage Processor<\/a> modules<\/li>\n<\/ul>\n<p>The panel format is a new one that I designed.&nbsp; It uses MOTM form factor (5U high by 2U wide), so that it can be mounted on standard MOTM rack rails.&nbsp; The vertical spacing of four columns is also the same as MOTM, but horizontally there are ten rows, spaced at 0.8 inches apart.&nbsp; These accommodate the banana jack format like I used on my previous CGS Serge panel.&nbsp; The panel is blue to match BugBrand.&nbsp; I ran into one hitch, not with this panel, but with others in the group that have pots in the top row.&nbsp; The pots protrude into the space needed by the rail, necessitating filing the rails a little.<\/p>\n<h4>Jack Colors<\/h4>\n<ul>\n<li>Yellow &#8211; Signal Input<\/li>\n<li>Green &#8211; Output<\/li>\n<li>Blue &#8211; CV Input<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h4>Knob Colors<\/h4>\n<ul>\n<li>Yellow &#8211; Signal attenuator<\/li>\n<li>Blue &#8211; CV Attenuator<\/li>\n<li>Red &#8211; Initial setting or Offset<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<h3>Passive Pots<\/h3>\n<p>As simple as it gets, these are just four independent passive attenuators.&nbsp; The pots get a ground wire to the power supply.<\/p>\n<h3>CGS VCA<\/h3>\n<p>I wanted a few more DC-coupled VCAs and chose the CGS VCA, which is based on the VCA3+ by <a href=\"http:\/\/www.schmitzbits.de\/\" target=\"_blank\" rel=\"noopener noreferrer\">Ren\u00e9 Schmitz<\/a>.&nbsp; Ken Stone added op amp buffers to the Schmitz circuit.&nbsp; I had expected to see the standard unity gain happening at around +5 volts of CV at the CV input, but it was only about 0.2.&nbsp; After some discussion with Ken on the CGS email list, I changed two resistors in the CV section to get the unity gain.&nbsp; My panel design has two signal inputs, which mix.&nbsp; These are easily patched from the Pots just above on the panel, if attenuation or input mixing is wanted.&nbsp; The red knob is the initial gain, and the blue knob attenuates the CV.&nbsp; The response is linear, and the signal quality is excellent.<\/p>\n<h3>&nbsp;Voltage Processors<\/h3>\n<p>Built with CGS81 PC boards, these are similar to other processors I&#8217;ve made with the board, but yet a bit different.&nbsp; There is one normal attenuated input, one bipolar attenuated input, an unattenuated auxiliary input, a bias knob, and normal plus inverted outputs.&nbsp; These are DC-coupled unity gain mixers, but of course will pass any audio signal, as well.<\/p>\n<h3>Construction<\/h3>\n<p>The three PC boards are mounted on two sides of an aluminum panel that fastens under a center row of banana jacks.&nbsp; Once again I used 4-40 nylon hardware to mount the boards to the panel.&nbsp; The power is distributed by jumpers, so that only one header is needed for the whole panel.<\/p>\n<p><a
