Nevertheless, I gave a little try to an VST synth using WDL-OL libraries some time ago, following Martin Finke's blog, but I finally came to the conclusion that there wasn't a considerable difference (compared to FS) in terms of latency and sound quality, to continue using archaic and tedious ways of programming.

Now, to be honest, I don't own a business and I'm not selling VST pluggins; at least, right now. I'm just learning how to use this beast called flowstone because it's the most productive development environment I've ever had the chance to use in my life. It's so "straight-forward" that I didn't even need the documentation to create a complete synthesizer with it, for the first time.


Well, yes, I can agree that FS is really cool and moreover, opens the universe of software development even for very poor skilled coders like me. But it still suffers from the not-existence of cross platform plugin rendering (for mac, linux, andorid, etc) and yet doesn't support a decent sample adopting method (like disk reading) nor advanced midi handling (for instance, working with midi files), so knowing other languages still has it's strong x-factor.

About your plugin: I tested it and it's sounds full of potential, but still needs a hard cooking. The syncing with the DAW bpm is yet not perfect and the step sequencer GUI is quite confusing. Also, the virtual keyboard doesn't respond to pressing ( I have no idea if that what you've been meant to do or just a bug...)

But overall it creates powerful and very musical note combinations and that's a huge reason to wait for a progress.

Thanks for sharing and keep it coming 8-)

I could not agree more.

This one is a little better and it includes help in some presets.
I tested it with 5 instances playing different arpeggios at the same time.

Yes, lot better now :D
Syncing work just fine and it sounds very "Nexusic" now. I wonder if the "random seed" option can be somehow integrated. I mean it generates a random seeded arpeggio and the note combination is automatically translated to drawn notes in the piano roll. That would be lovely as a feature.

Thank you, Halon!

And yes, that's the idea , Kortezzzz.

:idea: A kind of "discovery arp" and "discovery seq" modes with the possibility of transferring the sequence you like to the "piano roll". It would be very inspirational and useful.

Good luck, Josevo. I would love to see the results. Anyway, another idea: Your random arpeggios generate 8 notes sequences. You can somehow make it generate upto 32 pure random notes and you're making something supreme ;)

Fractal formulas are better than random values for music creation.
I just came up with a formula based on Z[n+1] = Z[n]^2+C
I made C = constant value (aka discovery) + position index
"...Et voilà, un universe de possibilités." :idea:

P.S :arrow: Now, even more editable.

It's definitely is! The editing aspect makes it much powerful now. The combination of generating thousands of randomized arpeggios with zero programming efforts + editing possibilities would make it even greater.

I have another question: I saw that your original code keeps generating 8 notes arpeggio combinations, no matter what is the actual selected speed \ numerator. I guess what it's actually doing is to play the first notes before it resets to zero according to the numerator (for example, in 1\6 mode, the time signature is actually set to 3\4 and only 6 of the 8 generated notes will play before it resets to zero).

I tried to do something interesting and increased the number of the generated notes to double size by changing the line "(step == 8) to "(step == @a)". then connected a knob to the ruby module which can change @a to 16 and back to 8. It worked and the arpeggiator started generating 16 notes combination seeds which is awesome! but when I went back to 8, it doesn't goes back to the original combination smoothly but kinda freaks out and looses the it's focus.

Perhaps it needs some kind of pos resetting or something every time the number of the steps get changed so it would go back to the original sequence? There is any way to do that?

Thank you once again, J.

I'm expecting that if the comparison regresses to step==8 while it is surpassed (when playing 16 steps), the counter doesn't reach the value and keeps growing forever.

Try this:
Code: Select all
if (@step >= @a)

instead of
Code: Select all
if (@step == @a)


That's why I don't like using == for stopping or resetting counters; although it's good for explaining concepts.
