strangebuttrue's synthesis sandbox

I’m throwing myself headlong into learning Rack and accumulating a few demo vids in the process, so I’ll post them here. I don’t think I’ve accomplished anything Earth-shaking, but several of these make me laugh, so that’s something. I’m not really a techno music fan so a lot of what I do with Rack is aimed in a direction oblique to most demo vids I see posted.

Here’s one I just finished - a six-channel, six-sequencer simulation of a guitar’s strings, programmed with common finger-picking patterns for the five open-voicing major triads (C, G, D, A, E). This patch has a a lot of potential - you could program it to do anything a guitar can do, short of setting it on fire or jamming it headstock-first into your speaker cone.

that’s cool! I love the Impromptu sequencers, but for something like this you might find mine is easier to use - and one polyphonic sequencer with a visual display will do the job of those 6 perhaps. Not sure. anyway nice to hear the finger-picking. Now just learn how to make some more appropriate sounds :wink:

I will certainly check that out. As far as sounding like a guitar’s tone, versimilitude is not really the main goal - I wanted to see if I could sequence Rack using guitar tablature as a mental model. A variation of this that might be amusing would be to double the whole construction, raise the three lower “strings” an octave, and detune everything, thereby simulating a 12-string guitar…

Here’s another. In the song “Ain’t No Woman Like The One I’ve Got” the Four Tops tell us that the subject of the song “can make the birds sing harmony”. Rack can also accomplish this. Here is a very dumb vocoder trick made with a Freesound recording of a nightingale. I’m hoping to build an audience for my tweets -

Here’s a slick little trick - Four sine oscillators read an array on which is written the sum of four sine oscillations oscillating at octave ratios to the oscillators reading them. A chord playing itself and voicing itself :sunglasses:


Here’s a pretty large control structure I spent a week or so working on. It’s a set of three array scanners that distribute control voltage in particular patterns across two banks of four channels. Why do I need this? It’s complicated. Does it work? More or less, though one part is a little shaky and it probably needs another mechanism to focus the voltages and etc. etc, etc,


I found a way more economical method of handling harmony than the above. This one is a fraction of the size and CPU demand and makes way better and more controllable harmonies. It all runs off a single 02NAGOL. Of course, the pitch selection system doesn’t appear in this video, but you can hear it…


Ok, so that sounds really good! What you’re doing there is probably a bit too clever for me to understand, :laughing: but the harmonies are lovely. :+1:
