ARP with RI (Random Intelligence) - Melody evolver

Hi Nic, anyone.

A few weeks ago I saw a video where someone named Lanthan O'Ide used an Arduino board to trigger a blofeld (Waldorf Hardware Synth).
He described his Arduino logic as follows:

As I was searching for informations about a Waldorf blofeld - yes, I want one - i was fascinated by that idea.

A few days ago I was reminded of StreamByter and what it should be capable of and I thought this was a perfect test to give it a spin.
So i was heading into the App-Store and bought a copy - as I did not want an Arduino board beside my iPad

After running into some trouble with loops inside StreamByter (Thanks Nic for letting me access the beta - where this is solved!) I put this script together.
I mainly resembled the same logic:



#arp with random intelligence - loop 004

# user definable presets are G0, G1, G10
# G0 = amount of repetitions per generated notebatch
# G1 = amount of notes in the generated notearray (size of G40+)
# G9 has to be the size of the amount of notes in G10 (missing a real array function here)
# G10 contains the hex values that are the source of the note generation. these get randomly selected.

There could be a few more checks for minimal number of notes given and stuff but software is never final

One additional check i will implement is this:
In the first randomly generated batch of notes it is possible that the first and last note of the target array are identical.
I will enhance that when I have a little more time.

All in all - if you feed logical numbers you'll get logical results and no crashes.

You just have to feed some permanent note stream into StreamByter and get an evolving melody of randomly selected and generated notes within your selected note-range.

I did a setup like this - StreamByter is fed with the ever identical notes from StepPolyArp Unit and sends the generated notes to SynthMaster ONE:


and the melody-generation started.
To have a demonstration I made a small, non-fancy, song and hosted it on SoundCloud:
StreamByter Demo on SoundCloud


Edit: The SoundCloud Link seems not to work properly...dont know why.
This is the plain Link:
https://soundcloud.com/user-842912842/streambyter-demosong-20180911


The "Bell-type" sound is initially randomly generated and evolves over time. So every time I start AUM playing that song it is different and evolves differently

I hope you like it and get some use for it.
I am very happy with my first StreamByter project.

Thanks Nic for the loop-problem support, again
