demo of taking the harsh square wave output of any kind of keyed CPO or CW Keyer's audio output - and RE-KEYING it exactly but transforming it to a pure sine wave CW NOTE with Raised Cosine edges (only takes 6 milliseconds from start to finish) uses ZAMGATE in SIDECHAIN MODE which has a pure sine wave TONE GENERATOR connected to Zamgate port 1, but the sine wave is held back from going through Zamgate to its output, until it is keyed by the harsh square wave keying Zamgate's port 2...once keyed, Zamgate also puts an adjustable amount of RISE/FALL time on its final CW NOTE output - it is trapezoidal until it passes through a very low latency HIGH PASS FILTER - LOW PASS FILTER combo from back to back FILTA plugins

Here is the same setup with PADDLES and a STRAIGHT KEY - also with all the APPs housed into one PLUGIN by the genius coding of the INGEN modular audio processing system APP
in this video CW PADDLES and STRAIGHT KEY are used to key all of the previous CW-RE-KEYER apps, that are now all put together as just ONE LV2 PLUGIN that was created using the INGEN modular audio processing system APP allowing you to bring it all back just the way you want to operate, after saving it the way you prefer...

Here is a live demo of using an MFJ 451 keying a TLC555 Tone Oscillator whose output goes to the input of the CW RE-Keyer system
this video is a brief demo follow up from the first video in this series here: https://youtu.be/ki5FbBIvAlQ
NOTE: the first video covers the CW RE-KEYER software APPs
this video shows the bread-boarded 555 circuit being keyed by an MFJ 451 CW KEYBOARD ...the output of the 555 goes to the PC's MIC INPUT JACK and then into the software RE-KEYING system as previously described in the previous video linked above NOTE: this particular 555 is powered from the MIC JACK VOLTAGE SUPPLY itself and no battery is needed...the TLC555 is operated at its lowest voltage supply region...
CW RE-KEYER setup for Windows 10 users
This is a follow up video from the previous one here: https://youtu.be/-MscxgmK9as - same setup, but for Windows 10, a different free BANDPASS FILTER VST PLUGIN is used - Mbandpass https://www.meldaproduction.com/MBandPass sine wave tone generator https://socalabs.com/developer-tools/tonegenerator/ ZamGate has a Windows VST PLUGIN version http://www.zamaudio.com/?p=976 CARLA VST HOST for windows https://kx.studio/Applications:Carla
Here is another example of using the CW RE-KEYER SYSTEM, with the YPLog CW keyboard at 60 wpm
similar to the previous video on this QRQ CW Re-Keying system https://youtu.be/ki5FbBIvAlQ this video uses the Engineers Filter VST Plugin for the CW bandpass http://www.rs-met.com/freebies.html ZamGate VST plugin in sidechain mode http://www.zamaudio.com/?p=976 SINE WAVE TONE GENERATOR VST PLUGIN https://socalabs.com/developer-tools/tonegenerator/ CW RE-KEYER SYSTEM PLAYLIST https://www.youtube.com/playlist?list=PLfFan4sDonOdFGeEDASG8tcadafH...
Here is another use for the CW RE-KEYER SYSTEM - practicing WHOLE WORD SOUND COPY using Fabian's QRQ APP

Specialized QRQ CW audio Raised Cosine filter by AD5DZ - 80 wpm test - LIVE demo using the CW RE-KEYER SYSTEM
demo of the filter module from AD5DZ's RECRI KEYER software APPs
https://github.com/recri/keyer
to demo this filter, a text file is sent at 80 wpm, with a harsh audio output to key the sidechain gate of ZAMGATE, which is one of the APPs used in the CW RE-KEYER SYSTEM :

https://www.youtube.com/playlist?list=PLfFan4sDonOdFGeEDASG8tcadafH... **************************************************
the output of the CW RE-KEYER SYSTEM, ZAMGATE, is a pure sine wave with TRAPEZOIDAL edges, at a certain RISE/FALL time that you select on the ZAMGATE controls ATTACK/RELEASE
this ZAMGATE OUTPUT goes to the input of the AD5DZ CW AUDIO FILTER where you dial in the bandwidth and the ORDER(length) until it suits your preference for COPY BY EAR...

Here is another development in this CW RE-KEYER - fine tuning the CW weight with better control
BRIEF demo of sending QRQ CW at 75 wpm, & showing the benefits of adding the ZAMGATE VST sidechain gate plugin before the reagate/sineCW64 plugin for CW REGENERATION, CW RE-KEYER SYSTEM setups.... the addition of adding ZAMGATE allows better fine tuning of the WEIGHT
- a 5 khz square wave tone was at the input of the CW RE-KEYER system for this demo
if you would like to test this sine64 VST3 plugin on your Windows 10 64 bit PC...you have to unzip & put this VST3 plugin folder into your - Program Files/Common Files/VST3 folder - and re-scan for vst plugins with your VST HOST
NOTE: not sure it will work without the synthedit 1.4 64 bit software installed and loaded once: http://www.synthedit.com/downloads/

good example of the harsh raspy square wave of a typical CW Keyer's audio output and then converting it to a pure sine wave CW NOTE with raised cosine edges - see and hear the difference
another demo using the CW RE-Keyer methonds from this playlist:
https://www.youtube.com/playlist?list=PLfFan4sDonOdFGeEDASG8tcadafH...
this video shows and plays the typical CW KEYER's harsh raspy square wave cw audio output and then converts it to a SINE WAVE CW note with adjustable, shaped, raised cosine edges and lets you see & hear it too...
using 3 VST PLUGINs
