Software and modules needed:
Reason Studios ver 12
Skope M4 by Lectric Panda
Skope by Lectric Panda
Polymodular System CV Splitter by Blamsoft
Little LFO by Little IO
The 3 oscillators (form Little LFO) are free running and can't be controlled by a MIDI keyboard, etc.
If you keep the "device view" open you can see the 3 oscillator waveforms in Skope M4.
The fourth window has the Filter waveform.
The Skope below that is the composite wave form of all the oscillators.
This combinator can be freely modified, reused, repackaged or whatever.
