I try not to care about things like analog and digital and just focus on discovering sounds and areas of exploration that are usable to me (even if sometimes in a noisy/chaotic way.)
I like this attitude-- let your ears be your guide! Although the Karplus-Strong algorithm is inherently digital, it was approximating something that was previously done with analog filters & delays. Your creation seems less like an approximation of K-S than an expansion on the forms that K-S was originally mimicking.
Back in the mid 80s when K-S was devised, it was special because good digital filters couldn't be done in real-time with cheap general-purpose CPUs. In its simplest form, K-S is computationally inexpensive: All you do is take the average of two consecutive samples and feed them back into the delay line. It produces a decaying tone whose period is set by the length of the delay.
The first implementation of K-S I saw was in 1988 or 1989 on a NeXT computer!
Very cool stuff! I appreciate this bit of history. I deal a bit with max4live and this makes me think it would be pretty trivial to whip up a K-S device.
Nicely done, philroyjenkins! I love hearing the REV2 do unexpected things. I've gotten some similar sounds while using a Max for Live device I designed to degrade parameters over time. The timbral possibilities in this machine probably exceed the number atoms in the universe, or at least the number of atoms in a medium sized piece of fruit. :-P
Thanks bud. I've been meaning to check that device out from ya!
I'm working on an arduino midi patch changer for the Rev2 with a simple 9 digit keypad to enter the patch numbers instead of using the program knob. To be honest I really only need one bank of patches and I prefer remember a numbering system to a naming one. 1-9 will be my favorites, 10-19 basses, 20-29 pads etc etc.
Anyways, I plan on adding in a special code entry to the keypad that will completely randomize every midi cc. Thought you'd appreciate that bit.
Love that "Burnt" one. Sounds like playing an instrument made of radio tower guy-wires.
Thanks man! That wiggle in pitch is thanks to the audio out mod source. Its become one of my favorite ways to add a bit of organic interactivity to an otherwise static patch.
I've been following your efforts to better approximate VCO behavior on the Rev2 and I just think its frickin awesome that this synth has this much potential for such varied experimentation on seemingly opposite ends of the sonic spectrum.
