PLS-21 Pitch/Depth Computer Logic Demo
I'm creating a Pitch/Depth Computer for my PLS-21 Turnkey Cutting System. Currently working out the logic in simple to code C#. The final logic will be ported to C++ embedded in a VST Effect. You will place an instance on your master output track in your DAW of choice. It will handle delay time, so you'll hear silence after hitting play for the correct amount of time as determined by your selected cutting speed (33.3/45/78/22.5/16.6). No need for a delay or doubling tracks in your DAW. Since all pitch and depth control messages can be sample locked to the audio there is no need for a platter strobe assuming your platter motor is relatively accurate. USB connection to the lathe is implemented as a HID Input device requiring no drivers to be installed. Direct digital control of both Pitch and Depth, calculated by the VST, all motor controller changes are sample locked to the audio/DAW's clock. Diameter Events for lead in and lead out are communicated to the VST from the lathe over USB. I already have the VST and USB Device code working and communicating with each other, including sample locked communications.
A separate MIDI VST control can be added to a MIDI track in your DAW which will allow you to sequence lathe control message. Notes of specific values automate things like start/stop/echo/head pop/etc. You could also turn off the Pitch/Depth computer and draw depth as a Continuous Controller or Pitch as Pitch Bend MIDI data.
For my own lathe to start. But, I can also make a USB breakout box which could be used with a Neumann or other lathes. Stay tuned!
