Subject description: How about a Lunetta Radio Show?
Reply with quote  Mark this post and the followings unread

Hi folks,

As you may know, I do a weekly broadcast on electro-music.com radio called The ChucK Show. I've given some thought to doing an occasional show about other aspects of our forum, and a Lunetta show seems like a good thing to try.

Depending on interest and amount of material, I may be able to create a prerecorded Lunetta show. If you would like me to include some of your Lunetta songs on the show, please post them to this thread. I'll take your posting to this thread as permission to broadcast your material.

Thanks,

Les

I'll throw my hat in. I -just- stapled this together. A few doubts though.
First: this isn't -really- lunetta stuff (man, there's a mood killer). The clock signals I'm using are standard cmos, but the noises are, for the most part, being generated by discarded antique microcontrollers (the brain from an old Cannon bubblejet for the first part and an Intel chip (circa '82!) from some bizarre keypad assembly for the second part). Whether this falls under circuit bending or lunetta is not my call to make.
Second: I used some Soundforge editting, this is assembled from three different nights worth of recording. Almost every part is composed of three different chunks mixed down (channels occasionally swapped). Other than that there's no external processing.
Third: This isn't fully autonomous or environmentally controlled. For the most part it's just the machines running amok, but a lot of the samples I ended up using caught me redhanded with my fingers on the potentiometers.

For lunetta purists, my lurking turned up 2 points of design philosophy: Components should be standard cmos logic chips. User involvement should be limited to turning the thing on.
Both of these are endlessly debatable, but both also strike me as noble design aims, especially the second. From pretty much any angle I trounce all over the first. My incursions against the second are however, I think, excusable.
That I multitracked likewise bothers me from a purist standpoint. If you want a tech demo of what a device is capable of, then recording a few hours worth of it making noise, trimming it up and layering it just seems like cheating.

Regardless, intro's a little slow but I think it's a fun track overall, especially considering the turn-around time in putting it together. I present "decaying orbit"

Great idea Les. Here's a bunch of mine

Flight of the oscillator
Just a bunch of clocks and loads of knob twiddling

Soundscape
Self playing patch with a ton of reverb

Whirlygig

Steampump
Messed up Lunetta + guitar mashup

Thanks for the material sizone and slacker, I'll wait to get some more Lunetta artist's work before putting together a pre-recorded show.

Hi Les
Here's some autonomous patches with my Lunetta. Luna11 is posted elsewhere on this board so some may have heard it already... but it's one of my fave's.

The machine is 4XXX CMOS except for 2 555 VCOs and some op-amps for mixing/summing (ie R/2R ladder) These are recorded in one pass, no knob twiddling and some light effects - delay and reverb for a little depth.

These things are addicting - my modular has sat mostly unused for the past 6 months as I spend my free build/music time with the Lunetta.

I've apparently got to finagle a little more upload space here.... so here's a link to Luna 15

http://deathlehem.com/php/download/file.php?id=416

and a quite recent - fresh and juicy, moist and tender Luna17
http://deathlehem.com/php/download/file.php?id=427

EDIT - Adding one more (just one, really!) from the archives. This one has more FX (delay and 'verb) than I usually use... but has some really great sounds, I think like the soundtrack chorus in your favorite sci-fi/steam punk/ancient action adventure modern mystery movie horror thriller. With Vikings.
Wink
http://deathlehem.com/php/download/file.php?id=69
I mixed several voices of the Lunetta in and out on this one...but it's otherwise autonimous...autonamous...automatomitonimouse...ahem..playing itself.

I realize there's more than you can use, but it might be nice to have someone else choose what they like rather than me - I'm a tad biased.

Good idea Les, thanks ! Here are a couple of recordings for ya.

-Birth of a Lunetta
My first recording of the machine when it was still housed in a cardboard box. The machine at the tme consisted of a 555 timer clocking a 4040 divider which was clocking a 4094 shift register, as well as some NAND, NOR, and XOR components.It was recorded and edited in Audacity.

The piece is meant to feel like a nightime chase through a busy city on foot. A normal day turns bad when our hero spots the bad guy coming toward him. A chase ensues where the hero comes closer and closer to being caught, in more and more dangerous situations. He finally loses the bad guy in a crowded nightclub.

http://droffset.com/sound/birthOfALunetta.mp3

-Coin Toss
The key module is taken from a novelty coin flip simulator, so there's a gate in, and when it's high the VCO oscillates like a madman, then when it's low there's a big capacitor that discharges and the oscillations slow down the flipflopping of these two LEDs for heads and tails until it stops and there's your coin flip result.

It's is a soundtrack of common sounds you'd hear in a casino on some alien cruise liner. Think Carneys with tentacles and big eyeballs.

First, I'd like to add my nod to the general consensus of this being a good idea. I've heard most of this stuff before, but it's nice to have it all in one thread. A few general compliments.
slacker: Soundscape's fantastic. I think I caught it on matrixsynth. Incidentally, on second listen, I'm pretty sure I used the 4017/4051 on a few parts in the last track.
bruce: -really- nice to have all of your stuff in one place. Put any more thought into setting up a stream?
droffset: 'till today I thought it was "droff set", like the set of all "droff" numbers. Anyway, the coinflip example came out nicely, hadn't heard it yet. More?

Tonight's effort's something on the drone/ambient industrial side. Work on the propositional logic circuit is temporarily halted, so I decided to mess around with some of the other chips I've been meaning to play with. The resulting song, while a bit dull, satisfies my purist leanings. First, it's nothing but cmos (though I guess the 40106 and 755s could be considered exotic) and passives, oh and some transistors. Second, there's no user involvement beyond the initial settings (well, and the mixing and editing). Again, it's a bit dull as I didn't have any real sequencer type circuits in the mix. This took about 4 or 5 hours to put together. Almost half of that was gobbled up in the editing phase. Only the oscillators and the OR gate were prewired. Everything else was breadboarded at the start of the project.
Adding tracks one at a time is still necessitated by a lack of clock signals (no, 10 isn't enough).

This is the hardware breakdown.

oscillators:
synthmonger's 40106 narrow pulse/falling ramp (5 voices stuffed, all with linear cv. Caps ranging from .01 uf -> 10uf)
555 fixed frequency/adjustable pw *5 (caps ranging from 1uf -> 10uf though I think I'm going to swap in some higher values)

1st track: The fuzzy bass drone
4015 shift register.

2nd track: Most of the sound
4089 rate multiplier (droffset, aren't you to blame for bring this chip up?)
and some of the oscillators being fed into a 4051 multiplexer.

3rd track: Midrange drone
4071 OR gate being fed by the pulse outs of the 40106. The cv ins of which are being modulated by the ramp outs.

Thanks again, folks! I've got enough material for one show now, but keep 'em coming if you like. I am particularly happy with all the descriptions and remarks because that makes for interesting things to read when introducing each song. This is only enhanced by sizone's detailed documentation of the circuits behind his last piece, which tells approximately how to reproduce the sound if one wanted to.

By the way, I was wondering if anyone had a link or some text about Stanley Lunetta. It would be good to say a few words about the originator I suppose, lol.

Cheers,

Les

I'm excited about this, Les! I fired up my lunetta for the first time in awhile this past week and have been experimenting with some modules I didn't much use before. The first clip is the result of these efforts, and it is very NOISY. The second clip is some audio-to-midi stuff I did in Bidule.

Thanks telstar, I enjoyed your songs. There is so much material here that I will have to select just one song from each artist, and save the rest for a second show. It will take me a while to let things percolate in my head, review the songs a few times, and compose a show so please be patient.

Les

I daresay you are breaking new ground here, Les. This may well be the first Lunetta Internet radio show in the history of the planet.

Woohoo! Heh, never thought about it that way. Tonight I will finally prepare for the show, reviewing the songs and compiling some text descriptions. Tune in to the show, it will be Friday at 7pm EST.

Les

Well, the show turned out very well, thank you to all who contributed. The recording is available here:

http://electro-music.com/forum/post-257840.html#257840

Keep those contributions rolling in and when we have enough material we'll do another show!

Here's a couple more from me, Les...
Maybe we can prod a few more submissions out of the Lunetta-Lurkers Smile

EDIT to add a pic as requested further down the thread...
What the heck - here's a vid as well.

Thanks bruce, I'm listening to StillStream right now, so I'll listen to these later. This brings the total for Lunetta Show #2 to 25 minutes, or in other words about half of a show. Hopefully we'll get some more contributions sometime soon, in the meantime I'll use these on The Game Show. Maybe if we do another show, Howard can summon Stanley to the chatroom again? I hope so, it was great to honor him the first time.

Les

p.s. I could always fill in the second show with a few songs from the first show, we'll see how it goes.

Man, that Luna7 is a nice patch. Is that your Lunetta box running solely on autopilot, or were you patching as it played?

Thanks clarke68 -
I kind of like the 'chorus' of voices sound that happened on this one...
Most of the Lunetta patches I record are just playing on their own. On this one I faded in the channels on the mixer at the start - and I may have faded a voice or two out and in again in the middle. The patch itself didn't change, and I think the clock speeds were left alone...

To me, the Lunetta is still fairly unpredictable. I don't know that I could improve the composition by messing about - and would probably make it worse.

I'll look forward to hearing some of your clips as you put things together...each persons Lunetta recordings seem have a unique character.

bruce
