MIDI KEYED - MORSE CODE SINE WAVE OSCILLATOR - with free software

This is an experiment in using free VST PLUGINS to create a MIDI KEYED morse code sine wave oscillator(software). It is "keyed" by MIDI INPUT. You can also use this midi setup to regenerate morse code audio tones from another source. FLdigi is used in the video for this purpose. Using MIDI to key a software CPO, shows great promise, since the accuracy of midi input keying is far superior to using a SERIAL PORT for this kind of a setup, in regards to accurate timing. Even at extreme QRQ CW…

Sending morse code over the internet with EhoCW

EhoCW has just released a new version which allows for multiple instances and the option of using WASAPI AUDIO.  WASAPI AUDIO DRIVERS are almost as good as ASIO DRIVERS in regards to cw timing accuracy and low latency.  Only EhoCW has the option to select WASAPI SOUND CARDS, no other software cw keyer was found that had this feature.  Two instances of EhoCW are used and setup exactly the same to send iambic morse code to two different sound cards - one instance to…
