A 4 SIDcog polysynth sounds very interesting; when will we see it?
I hope soon... polyphonic play from MIDI it's working, one voice per chip (dual osc), with voice allocation and pitch bender. But I'm a little stuck with modulations and patch management.
Maybe it's better to just implement ENV3->[EnvAmt]->Cutoff and OSC3->[ModWheel]->Pitch for a first version.
I'm doing global mix with StereoSpatializer object, it works great with a tiny mod to SIDcog mixer code:

BTW, you must be kidding when you say you're not a graphic artist: that logo it's fantastic and perfectly fitting the theme, IMHO.
I had also PM'ed him last night asking a similar question. Hopefully he'll skip my PM and just answer here. I'm betting he's come up with an "ideal" configuration for Propeller audio.

I am not kidding when I am saying that I am not a graphics artist; I think this was my first logo ever!!!
And I am very interested in your SIDcog project. How about starting a new thread and post your progress??
Great work guys! We've been planning to reanimate this old two level organ that we saved from the dumpster couple of years ago with propeller
and Ahle2s cogs (ie SIDcog and AYcog played from different levels) and in the same day i got the Propellers I notice this post.
I'm definetely interested for beta testing and because we're planning to make it first be playable with midi keyboard I'm very interested about
that polyphonic SIDCog project too.
BTW Retronitus sounds like a tinnitus in a nice way. Like some sid playing always on your head .
Actually we have this saying with couple of old sid geeks that if you have some **** playing in your head that you cannot get rid of just listen couple seconds of airwold.sid
I am just coming off of a work project. Checking in to find the video I was waiting for. That is very good sound! We SO need a nice tracker, and a feed from SD card. Hearing that makes me want to compose chip tunes!
If you remember the turbulence demo linus coded - including a special code-compression and linking algorithm -
I guess you can send him uncommented code and he will see it as a challenge to disassemble it by hand.
He is a musician like you and did a lot of projects about electronics, software and music.
I hope you guys did not think that is my rig. That was a "random" clip I found on Youtube.
I do have two subtractive synthezisers, but not a wall of them.
@StefanL38
I'm quite familiar with Linus work, and I do know that he is a code wizard.
So I know that he is able to read the code. But it's still not very readable.
All the sound files have been edited in "Retronitus Sound Editor".
It will, however, take some more days/weeks before "Retronitus Sound Editor" is completely finished and Retronitus is released.

I'm curious, how did you come up with the name Retronitus? I get the first bit Retro, but nitus???

sonitus = noise, sound
Retrosonitus didn't sound quite right!
Can you share with us the schematic for this as well (I'm guessing it's pretty standard except the audio portion).

Yeah, it sounds like you'd need a tablet for that!
Logo is looking good too!

I am not a gamer otherwise I would offer, though I will be glad to test on my new h/w.
I guess what I should have asked is how you're filtering the output.

100 ohms / 0.1uF will give a good result and have a cut off frequency of: 1/(2 * Pi * 100 * 0.000001) = ~16 kHz.
Thanks fo the kind words!
And I am very interested in your SIDcog project.

Thanks Ahle2!
Firstly I just want to say; Welcome to this forum !
Yet another interesting project based on SIDcog.(and Aycog)
There are currently three interesting projects going on based on SIDcog.
1. porkotrons SIDcog/AYcog organ
2. Toymakers SIDcog organ
3. AntoineDoinels midi driven subractive synthesizer based on SIDcog
It seems like people are enjoying my contributions to the Propeller.

Can't wait to have a look at the code...
I have tinnitus. The only nice thing about it is that it almost drowns out the voices :-)
Long time no seen! What have you been up to lately? Any new Propeller based project?
(The code isn't very readable, I used every trick in the book so to speak.
The tune is familiar to anyone following this thread.
wow impressive studio.

I haven't done very much using propellers recently, although I made a slide projector for a seminar. Right now I'm learning my way around FPGAs.
By the way, I assumed the code would be full of trickery. That's what's going to make it an interesting read.
Deadmau5 is hardly a random clip...
The main point of this teaser is to demonstrate how easy Retronitus is to use.
