<p>2. midiCW from: <a href="https://github.com/recri/keyer" target="_blank">https://github.com/recri/keyer</a></p>
<p>what is notable about this setup, is the extremely low latency for CW REGENERATION...it only takes @300 micro seconds to re-create a raised cosine cw element from the "original sidetone"</p>
<p>here is a picture demonstrating this: The GREEN waveform is the "original sidetone from a 555 timer chip being keyed by a typical cw keyer, the RED waveform is the new recreated cw sidetone from midiCW...</p>

<p>Basically, the audio output of the 555 goes to the mic jack input and then to the first Linux audio app called TRIGGER MIDI MONO, TRIGGER MIDI MONO only has to measure the incoming volume levels of the 555 cw sidetone....then it takes the top peaks of those 555 cw elements at their start and finish, keyDOWN, keyUP, etc...and converts them into a midi message data output, that keys the second Linux audio app....midiCW.......midiCW operates just like a hardware cw keyer... the waveform output of midiCW is a raised cosine set to whatever rise & fall time you desire.... </p>
<p>here is a picture of what the setup looks like inside the JACK AUDIO CONNECTION BAY - Catia </p>

</strong></span></p>
<p>This video demonstrates how to use some vst plugins and FLdigi to create your own customized QRQ CW code practice oscillator. FLdigi QSK Right Channel audio output, is used to "key" a specialized software VST INSTRUMENT called MPowerSynth which creates a very clean and high fidelity code practice oscillator.</p>
<p>The morse code sending text is from W4BQF's famous article:<br/><a href="https://sites.google.com/site/tomw4bqf/copyingcwover70wpm" target="_blank">https://sites.google.com/site/tomw4bqf/copyingcwover70wpm</a></p>
<p>MINIHOST MODULAR VST HOST is used for this to input the RT CHANNEL audio from FLdigi and send it to "key" MPowerSynth.</p>
<p>MPowerSynth is very accurate in qrq cw timing, and has a great sound that you can customize to your preferences for QRQ CW in pitch and rise/fall time and even weight by percentage and weight by "compensation" using the FLdigi QSK CONTROLS.</p>
<p>Reagate VST plugin receives the RT CHANNEL audio output from FLdigi and then creates an extremely accurate conversion to a midi message which then "keys" MPowerSynth.</p>

<p>NOTE: an extreme qrq speed is used to demonstrate and show how effective this setup is for producing a very good QRQqCW note. FLdigi of course can send great cw on its own, but you can not adjust COMPENSATION using FLdigi by itself, and for QRQcw, sometimes being able to use negative "compensation" is helpful to bring out better copy...the MPowerSynth also has a final polishing AUDIO BAND PASS filter , which makes a huge difference in edge noise at the higher speeds.</p>

<p>HERE IS A COMPARISON PICTURE OF AN ORIGINAL FLdigi WAVESHAPE of the LETTER "R" on TOP and a recreated LETTER "R" via this AUDIO to MIDI technique(SATYR CPO)on the bottom- -also THE SATYR CPO is using the FLdigi RT CHANNEL QSK function to trim off a tiny increment of time via negative compensation - a few milliseconds, the same amount off of both the dit and dah. At your top copy speed I have found this to be a great feature to help "fine tune" the QRQq cw sending to make for better copy.…</p>
<p>HERE IS A COMPARISON PICTURE OF AN ORIGINAL FLdigi WAVESHAPE of the LETTER "R" on TOP and a recreated LETTER "R" via this AUDIO to MIDI technique(SATYR CPO)on the bottom- -also THE SATYR CPO is using the FLdigi RT CHANNEL QSK function to trim off a tiny increment of time via negative compensation - a few milliseconds, the same amount off of both the dit and dah. At your top copy speed I have found this to be a great feature to help "fine tune" the QRQq cw sending to make for better copy. The AUDIO to MIDI technique (using SATYR as the CPO) followed by a software BESSEL FILTER effectively "clones" the original FLdigi wave shape. The AUDIO to MIDI technique for regenerating FLdigi cw tones, also allows one to use the RT CHANNEL FLDIGI QSK function to further dial in some desired characteristics of the QRQq sending.</p>

<p>HERE IS THE LETTER "R" at 125 wpm, FLdigi by itself on TOP and SATYR's regenerated cw on bottom</p>

<p>HERE ARE THE FLDIGI SETTINGS THAT I LIKED for this experiment using QSK RT CHANNEL only</p>

<p>THE SETTINGS WERE MODIFIED ON SATYR to these, all TIME to bottom, all LVL to top</p>
