yesterday I saw a youtube video by “look mum no computer” where he was using a TV as an oscilloscope to get some of those Lissajous type things.
looked like fun, and i wondered what I could do with ETC modes…, and came up with this
what im doing here is the X/Y directly from my AE Modular using the audio stereo signal , where left = x , right = y. for course given the audio input on the ETC/Organelle is DC couple you cannot drive it in the same way as an oscilloscope, so here its just a similar concept where wiggling a modular can give you different patterns
a) I had to extend the ETC code base a bit, as audio_in is just a mono input, so I extended it to have an audio_left and audio_right
(ok, I admit, ive wanted to do this for a while, as I think playing with the stereo field generally can be useful for modes, even if its just to create ‘panning effects’)
b) im using alpha channel to create the trail, so it has a similar effect to a oscilloscope.
of course, truth be known for Lissajous effects on a etc, you dont even need an audio signal, you can just do it with some sin/cos functions… but wheres the fun in that
another option of course, is to driving it via midi, assuming the data rate can keep up… might be fun with a midi sequencer, like the pyramid, which can do midi LFOs.
anyway, just some fun, and perhaps might be interesting to others.
