<p>If you take a look at the PLUGIN GUI, you will see several parameters. The most important are the ATTACK and RELEASE....which sets the RISE and FALL time of the cw note. The 2nd to last PATCHVALUE is also interesting, you can vary the "hardness" of the keying by selecting one of the other options here, ie EXPONENTIAL . Send a cw file and adjust these 3 parameters while listening LIVE, to get everything set to your desired sending cw "sound"</p>
<p>NOTE:</p>
<p>Please find attached the download link if you are interested in testing this VST PLUGIN on your computer system. This is a 32 bit only VST PLUGIN. Place this dll file into your VST 32 BIT folder and rescan your VST HOST to pick it up...</p>
