seriously I always thought Lunettas where all about bleeps and buzzzz but this has certainly changed my way of thinking. If this was released on 12" I would play it, crazy stuff
Edit: are those samples unprocessed? |

Yes, unprocessed, just straight into my sound card. |

Great work, and great sound !
I just wanted to ask for a little bit more informations about this :
Quote: | 1x swing generator.
a swung clock is outputted at 1/4 the speed of the input clock. there are 5 values to be chosen via a rotary switch. I believe the values are 25%, 37.5%, 50%, 62.5% and 75%. reset in, clock in, and swung clock out.
|
I think this is your secret weapon, why you have a nice swing feeling in your rythms ! Is it true ?
Can you explain how this works ? _________________ My Scoopit DIY Synths and Schematics curation |

What chip is used for the swing generator? Schems? _________________ What makes a space ours, is what we put there, and what we do there. |

I know it's been almost a year since the last post on this thread, but I was wondering if the schematics were still available for this. The sound samples are amazing, and I'd really love to build something like this for myself. Thanks! |

no problem. i have pcbs that i've made that contain the 4 drum oscillators on it, if you are interested.. right here http://electro-music.com/forum/topic-52854.html
im working on getting a page set up to sell it from, in kit and pcb form. |

Hi Psyingo.
From your 4011 PCB thread:
Psyingo wrote: | baudrate wrote: | The board and a surprise chip showed up today. Thanks a bunch! |
yeah, i was worried that it wouldnt work with certain chips, so i sent it with chips that i tested...
don't hesitate to shoot me a pm if you have any questions |
I've been playing with your original circuit on a breadboard and I've had rather variable results. Sometimes I get decent percussive sounds and other times constant low frequency oscillation (even with differences on two gates on the same 4011). I've tried several 4011s and failed to get everything working. Do you know what the problem with some chips is caused by, or which ones are likely to work? Of course, it's possible that I've just screwed up, but I've been checking/rechecking/rebuilding and I'm still having problems...
Thanks,
Gary
BTW: This is a great machine! |

Hey, sorry for the belated reply.
one chip that i've found to work is the STMicroelectronics 4001BE (thats right, buffered...!)
I'm not certain why some chips work, and some don't. the internal circuit design of CMOS ic's varies wildly between manufacturers.
but ive found usually that if it works on one gate it works for the rest. although, im sure thats not the case for every ic.
i've gone between using 100k resistors and 47k resistors for R1/2, although i don't think this would cause the differences.
you could also try using 4069 NOTs as your gates instead of NAND/NOR... the only reason i used 4011/4001 was because thats what i had in the random cmos bag .
I do wish the chips werent so variable, but we are trying to build analog audio devices using stuff meant for digital logic. its not going to be ideal by any stretch.
FUN FACT: the suzuki omnichord OM-84 uses a similar set up to get its drums, as shown in this schematic http://www.voxinfinitus.net/~psyingo/OM-84_schematics.jpg at IC15. although,that one is a bridged-t, as opposed to a twin-t.
anyway... sorry i dont have any more concrete advice to give you. i have found that some ic's will give just humming, or distorted bips, or just clicks while some will give the proper percussive sound... :/ |

Thanks for the reply Psyingo. I'll have to give the 4001B a go. I've got quite a few of those from 3 different manufacturers (but none are STM ). I did try 4069s out, but still had problems. I've been playing with the old Elektor twin-T design posted by YuSynth here:
http://electro-music.com/forum/viewtopic.php?highlight=twint&t=28541
This does work, but I'd like to try your idea again, as it has separate pitch and resonance control. I'll let you know if I have any success (and with what).
Cheers,
Gary |

here is the schematic i used to build the drums... maybe this will help more than my crude sketchbook one? http://www.voxinfinitus.net/~psyingo/electronics/schematics/rw_quadrum.png |

Thanks a lot for that Psyingo - that's much easier to read than the sketchbook . I'll have another try at this circuit (probably tomorrow, as I'll be out most of today). As I said, I'll let you know how it goes.

Sorry for the delay - I haven't given up on this. I tried an HEF4001BP which did seem to work a bit (but not as good as yours did). Many of my other 4001/4011s gave very poor results.
At the moment I'm cheating (Lunetta-wise) and I'm using an LM324 with part of a modified CGS drum design (which I've changed to a single rail supply to make it Lunetta friendly) - see Ken's design here:
http://www.cgs.synth.net/modules/pic/schem_cgs18.gif
I'm still triggering with your 4503 circuit. Would this work with more conventional buffers (e.g. the 4050)? I'll probably give it a go and see what happens. Anyway, I'm getting quite good (tom-tom) drum sounds from this Frankenstein circuit. If it is good enough, I'll post my schematic (making sure to credit everyone involved).

oh wow! This sounds just fantastic. I had no idea CMOS stuff could actually achieve anything like this. I'm dreaming of drum machine of my own |

awesome sounding (the drumsounds but also the sequencer section is very tight!)
->perfect for electropop!
this is very inspiring to me, COOL diy!!! |

It looks like the etsy shop is empty and that the conversation ended while trying to get instructions together. Are any kits or boards available? A tested schematic? I usually build full MOTM analog modules, but really loved the sound samples and would LOVE to build this thing. |

can't say nothing more than wow!!! abolutely amazing cool device you've built... sounds awesome...
put this one on my to do list as well...
any more detailed schematics available maybe your Hand drawn schematics just scanned for better reading??? |

I dont know if Psyingo is still looking in this thread, or if someone else may answer my questions. This Drum Machine inspired me, to do one myself, loosely based on the ideas in this thread.
Question 1: I want to build the Gate to Trigger Converter from your sketch. i never worked with buffer before. i think i can just put the "dis"-input to ground, right?
Question 2: A question wich i was asking myself since day one, but still couldn't answer. Whats the use of the Pulse stretcher. I see the Gate to Trigger Converter is there, because of the logic-gates. One still needs long gates for passing through them, and afterwards convert it to short triggers for the drums. But the other way round? Is it just for playing the drum modules in a more "experimental way"?
here is my project, but no results so far http://electro-music.com/forum/topic-62462.html _________________ https://soundcloud.com/ruebezahl |
